Accelerating Video Understanding for ad generation with Visual AI Agents

PYLER supercharges video ad safety with NIVDIA's DGX B200 and AI Blueprint for smarter, safer placements.
Discover how PYLER's real-time video understanding helps brands like Samsung, BYD, and Hana Financial thrive.


At PYLER, we leverage our platform, video understanding AI, which deploys visual AI agents to ensure brand safety by verifying that ads are never displayed alongside inappropriate videos and placing them in more contextually relevant settings to protect brand value and enhance campaign effectiveness.

With the explosive growth of generative AI, the sheer volume of content uploaded to video platforms has skyrocketed. In such an environment, displaying ads next to content that’s not brand aligned increases marketing costs to target the correct audiences, but also presents a risk of negative brand impressions and potential reputational damage.

Video Understanding AI is crucial for effectively managing and validating content in an era of massive, high-speed uploads. When properly implemented, it becomes a key asset in safeguarding and enhancing a brand’s overall value.

Video content processing is significantly more complex than image or text processing, demanding substantial computational resources from preprocessing to inference. To handle this real-time influx of video content effectively, a high-performance pipeline utilizing optimized computing resources is essential.

In this post, we’ll discuss how PYLER addresses these challenges by adopting NVIDIA AI Blueprint for video search and summarization (VSS) in conjunction with NVIDIA DGX B200 systems. We’ll explore how we pair NVIDIA software and accelerated computing, with PYLER’s proprietary Video Understanding AI, to help ensure brand safety at scale.


PYLER Boosts Content Safety with NVIDIA AI Blueprint for VSS and NVIDIA AI Enterprise

    • PYLER rapidly searches and verifies vast amounts of video embeddings, leveraging Context-Aware Retrieval-Augmented Generation (RAG). This supports automated summarization, indexing, Q&A, and content validation tasks, significantly improving inference speed, accuracy, and context-awareness.


Expected Outcomes for PYLER

With these integrations, PYLER’s Video Understanding AI software can provide:

  1. Maximized Brand Safety

    • Precisely filter, classify, and recommend safe ad placements, ensuring ads never appear next to inappropriate or harmful content.

  2. Enhanced Brand Trust

Why is "Storytime" Content So Popular on Korean YouTube? Understanding Risky Video Content for Brand Advertising

Korean YouTube’s “storytime” boom hides risky content beneath viral narratives.
Learn why brands must watch where their ads appear — before trust turns into backlash.


One notable trend on Korean YouTube is the immense popularity of what Koreans call "ssul punda" (썰 푼다), which translates to creators sharing "storytime" videos, or personal anecdotes, in a casual and engaging way. If you're familiar with Korean YouTube content, you’ve likely already come across this phenomenon. 

These videos feature individuals sharing a wide range of tales, from humorous dating mishaps and strange encounters with colleagues to behind-the-scenes celebrity gossip and shocking accounts of specific events. Whether based on true experiences or creative fiction, these emotionally charged stories often perform well with the YouTube algorithm. However, this type of content can also harbor harmful elements such as fake news, sensationalized narratives, hate speech, explicit sexual experiences, and even stories about suicide attempts.

This raises the question: why is this "storytelling" format so prevalent and popular specifically on Korean YouTube, and what do advertisers need to keep in mind?


What is "Storytime" Content?

From the perspective of PYLER's brand safety solution, 'AiD', "storytime content refers to videos where the primary purpose is to convey true or fabricated stories and share gossip. Think of it as online storytelling. This style of sharing narratives has deep roots in Korean online culture, with many popular internet communities fostering a tradition of sharing personal accounts. On YouTube, common examples of content range from dating scandals, family conflicts, and workplace rumors to reviews of sex work establishments and accounts of failed suicide attempts – often prioritizing sensationalism over public interest.


Harmful "Storytime" Content: A Greater Risk in Korea

We searched for the same keyword—"grandmother"—on YouTube in four different languages: Korean (할머니), English (grandmother), Chinese (奶奶), and Japanese (おばあちゃん). The results revealed a stark contrast: when searched in Korean, the platform predominantly surfaced provocative "storytime" videos. In contrast, the English, Chinese, and Japanese search results mainly featured wholesome family content, informational vlogs, or cultural introductions.

This discrepancy goes beyond mere algorithmic variation—it highlights the overproduction of sensational, story-driven content in the Korean YouTube ecosystem. Narratives often revolve around sexual experiences, personal conflicts, or violent incidents, with creators prioritizing shock value and algorithmic optimization over ethical storytelling or content quality.

As a result, brands advertising in Korea face a significantly higher risk of having their ads placed alongside harmful storytime content compared to other markets. Over time, this misalignment can pose a serious threat to brand image and consumer trust.


Why is "Storytime" Content So Dominant in Korea?

While similar formats like "Storytime" or "Personal Confession" content trends exist internationally, they haven't achieved the same level of mainstream popularity and genre establishment as this "storytime" content in Korea. Korean "stories" have become a distinct genre due to a combination of factors: rapid audience engagement, immersive narrative structures, and narratives often based on anonymity.

  1. A Community Culture Familiar with Sharing Stories Online: For a long time, Korean online communities like DC Inside, Nate Pann, Blind, and Today's Humor have been active spaces for anonymous "story sharing." This established method of narrative delivery naturally extended to YouTube, making the consumption of video-based "storytime" content feel familiar and accessible.

  2. Influence of Broadcast Formats: Popular Korean talk shows like "Knee Drop Guru" and "Radio Star" frequently feature guests sharing personal anecdotes and experiences. This long-standing exposure to spoken storytelling in mainstream media has created a viewing culture that readily accepts "stories from good talkers" as engaging content.

  3. Anonymity and Third-Party Storytelling: Unlike direct first-person confessions, Korean "storytime" content that relays or reports others' stories in the third person is also widely consumed. Reconstructing events, narrating urban legends, and summarizing incidents can generate high levels of immersion, making it easy to diversify content formats.

  4. Low-Cost, High-Engagement Format Combined with Algorithms: "Storytime" content can often be produced simply with text-to-speech narration, without the need for cameras or extensive editing. Its emotionally engaging narrative structure and clickbait-style titles align very well with the YouTube algorithm. This allows creators to achieve high view counts with relatively low production costs.


What About Overseas?

While "Storytime" content exists in English-speaking countries like the United States, its nature and consumption patterns differ.

Why Should Brands Pay Attention to This Phenomenon?

This "storytime" content presents a high-risk environment for advertising. However, many brands are currently running ads without fully understanding these risks.

Key Risks:

  • Risk of Context Distortion: When a brand's advertisement appears within content dealing with personal misfortunes or social conflicts, it can lead to negative associations between the brand and those issues.

  • Emotional Mismatch: Exposure to content featuring topics like sex work, suicide, or hate speech can severely damage a brand's image and reputation.

  • Decreased Credibility: The truthfulness of "storytime" content is often questionable, making it highly susceptible to fake news or defamation. Appearing alongside such videos can erode trust in the brand itself.

In fact, PYLER's analysis of advertising campaigns has revealed cases where up to 35% of the brand’s ad budget was spent on content inappropriate for the brand. This highlights the reality that even branding-focused advertisements are being placed in unsuitable environments.


An Advertising Environment that Considers Content Context is Necessary

This "storytime" content is not just a passing trend; it's a sensational narrative structure that is highly optimized for the YouTube algorithm. However, with harmful content like depictions of sex work, suicide, violence, hate speech, and fake news being circulated under this "story" umbrella, it has become crucial for brands to prioritize a safe advertising environment that considers content context as much as advertising efficiency.

To this end, PYLER monitors real-time ad placements and blocks ads from appearing on inappropriate content, providing a safe and high-performing advertising environment. PYLER is committed to helping brands connect with consumers in a safe and healthy content ecosystem.

AiD: Solution That Protects Brand Trust

AiD by PYLER is a real-time brand safety solution that uses multimodal AI to automatically detect and block harmful content, improving both brand trust and ad performance. Built to meet global standards, it ensures brand messages are delivered in safe and effective environments.


PYLER’s New Standard for Brand Safety in Digital Advertising

Even as digital advertising becomes more sophisticated, many brands still face a fundamental challenge—the risk of ads appearing next to inappropriate content.

Violent, sexually explicit, politically or religiously biased, and hateful content can seriously damage brand perception. According to a global consumer survey, 64% of respondents said they lost trust in a brand after seeing its ad next to inappropriate content.

To solve this problem at the technological level, PYLER developed AiD, a real-time brand safety solution that automatically detects and blocks sensitive content in video-based ad environments—ensuring that brand messages are delivered in safe and effective contexts.


Fighting Fake News and Content Farming

One of AiD’s core priorities has been identifying and blocking fake news and manipulative content formats, such as clickbait or "storytime"-style videos that distort facts or spread false narratives.

On YouTube, this issue extends to “content farming” or “cyber re-uploaders”—channels that repurpose sensational material to exploit algorithms for visibility and revenue. When ads appear on these types of videos, brands can unintentionally become associated with misinformation or social division.

To prevent this, AiD excludes related content under its “Controversial Issues” category. Its AI models are continuously updated to respond to evolving content types and social issues, ensuring scalable and responsive brand protection.


Real-Time Filtering with Multimodal AI

AiD goes beyond basic keyword filtering. It uses multimodal AI, which analyzes both visual and textual elements of videos simultaneously. Through PYLER’s proprietary Vision Analyzer and Text Analyzer models, AiD classifies and blocks content related to Sexual content, Hate speech, Political or religious bias, Controversial or sensationalized “storytime” narratives etc.

AiD also supports custom filter criteria, allowing campaign-specific brand safety rules. As a result, advertisers can instantly assess content risk levels and ensure that their ads are placed only in safe, brand-aligned environments.


Proven Performance in the Field

AiD has already delivered tangible results in live campaigns:

  • 97% reduction in ad exposure on sensitive content

  • 15% improvement in ad performance (e.g., CVR)

  • 639% reduction in wasted ad spend on high-risk content

In one case, a brand reduced sensitive-content ad spend from 16.1% to just 2.1%, dramatically improving both efficiency and return on investment. AiD delivers the rare combination of trust protection and performance enhancement.


Built for Global Brand Safety Standards

AiD isn’t just functional—it’s also compliant with global brand safety guidelines.

PYLER is the first Korean company officially registered with the IAB Tech Lab, and AiD evaluates and filters content based on IAB’s globally recognized standards. These guidelines are used by the world’s top advertisers, making AiD a technically verified and transparent solution.


Globally Recognized Technology

AiD is powered by PYLER’s proprietary video AI, which has been internationally acclaimed:

  • CVPR 2022: 2nd place globally in Video AI (competing with Intel, Tencent, ByteDance, etc.)

  • CVPR & ICCV 2023: Research accepted by the world’s top AI conferences

  • 2024: Selected for both NVIDIA and AWS Global Startup Programs

PYLER continues to refine its technology in collaboration with global tech leaders.


Redefining the Basics of Advertising

In today’s digital landscape, advertising is no longer just about what you say—it’s about where you say it.

The context in which ads appear now directly impacts brand trust and consumer decision-making. AiD eliminates the need for manual review or guesswork. It enables advertisers to automatically avoid risky placements and run campaigns with both safety and efficiency in mind.

Now is the time for brands to make a strategic, technology-driven choice—to speak only in spaces that match their values. At PYLER we are committed to creating a safe space for brands to communicate confidently, backed by AI and built for the future.

Why is "Storytime" Content So Popular on Korean YouTube? Understanding Risky Video Content for Brand Advertising

Korean YouTube’s “storytime” boom hides risky content beneath viral narratives.
Learn why brands must watch where their ads appear — before trust turns into backlash.


One notable trend on Korean YouTube is the immense popularity of what Koreans call "ssul punda" (썰 푼다), which translates to creators sharing "storytime" videos, or personal anecdotes, in a casual and engaging way. If you're familiar with Korean YouTube content, you’ve likely already come across this phenomenon. 

These videos feature individuals sharing a wide range of tales, from humorous dating mishaps and strange encounters with colleagues to behind-the-scenes celebrity gossip and shocking accounts of specific events. Whether based on true experiences or creative fiction, these emotionally charged stories often perform well with the YouTube algorithm. However, this type of content can also harbor harmful elements such as fake news, sensationalized narratives, hate speech, explicit sexual experiences, and even stories about suicide attempts.

This raises the question: why is this "storytelling" format so prevalent and popular specifically on Korean YouTube, and what do advertisers need to keep in mind?


What is "Storytime" Content?

From the perspective of PYLER's brand safety solution, 'AiD', "storytime content refers to videos where the primary purpose is to convey true or fabricated stories and share gossip. Think of it as online storytelling. This style of sharing narratives has deep roots in Korean online culture, with many popular internet communities fostering a tradition of sharing personal accounts. On YouTube, common examples of content range from dating scandals, family conflicts, and workplace rumors to reviews of sex work establishments and accounts of failed suicide attempts – often prioritizing sensationalism over public interest.


Harmful "Storytime" Content: A Greater Risk in Korea

We searched for the same keyword—"grandmother"—on YouTube in four different languages: Korean (할머니), English (grandmother), Chinese (奶奶), and Japanese (おばあちゃん). The results revealed a stark contrast: when searched in Korean, the platform predominantly surfaced provocative "storytime" videos. In contrast, the English, Chinese, and Japanese search results mainly featured wholesome family content, informational vlogs, or cultural introductions.

This discrepancy goes beyond mere algorithmic variation—it highlights the overproduction of sensational, story-driven content in the Korean YouTube ecosystem. Narratives often revolve around sexual experiences, personal conflicts, or violent incidents, with creators prioritizing shock value and algorithmic optimization over ethical storytelling or content quality.

As a result, brands advertising in Korea face a significantly higher risk of having their ads placed alongside harmful storytime content compared to other markets. Over time, this misalignment can pose a serious threat to brand image and consumer trust.


Why is "Storytime" Content So Dominant in Korea?

While similar formats like "Storytime" or "Personal Confession" content trends exist internationally, they haven't achieved the same level of mainstream popularity and genre establishment as this "storytime" content in Korea. Korean "stories" have become a distinct genre due to a combination of factors: rapid audience engagement, immersive narrative structures, and narratives often based on anonymity.

  1. A Community Culture Familiar with Sharing Stories Online: For a long time, Korean online communities like DC Inside, Nate Pann, Blind, and Today's Humor have been active spaces for anonymous "story sharing." This established method of narrative delivery naturally extended to YouTube, making the consumption of video-based "storytime" content feel familiar and accessible.

  2. Influence of Broadcast Formats: Popular Korean talk shows like "Knee Drop Guru" and "Radio Star" frequently feature guests sharing personal anecdotes and experiences. This long-standing exposure to spoken storytelling in mainstream media has created a viewing culture that readily accepts "stories from good talkers" as engaging content.

  3. Anonymity and Third-Party Storytelling: Unlike direct first-person confessions, Korean "storytime" content that relays or reports others' stories in the third person is also widely consumed. Reconstructing events, narrating urban legends, and summarizing incidents can generate high levels of immersion, making it easy to diversify content formats.

  4. Low-Cost, High-Engagement Format Combined with Algorithms: "Storytime" content can often be produced simply with text-to-speech narration, without the need for cameras or extensive editing. Its emotionally engaging narrative structure and clickbait-style titles align very well with the YouTube algorithm. This allows creators to achieve high view counts with relatively low production costs.


What About Overseas?

While "Storytime" content exists in English-speaking countries like the United States, its nature and consumption patterns differ.

Why Should Brands Pay Attention to This Phenomenon?

This "storytime" content presents a high-risk environment for advertising. However, many brands are currently running ads without fully understanding these risks.

Key Risks:

  • Risk of Context Distortion: When a brand's advertisement appears within content dealing with personal misfortunes or social conflicts, it can lead to negative associations between the brand and those issues.

  • Emotional Mismatch: Exposure to content featuring topics like sex work, suicide, or hate speech can severely damage a brand's image and reputation.

  • Decreased Credibility: The truthfulness of "storytime" content is often questionable, making it highly susceptible to fake news or defamation. Appearing alongside such videos can erode trust in the brand itself.

In fact, PYLER's analysis of advertising campaigns has revealed cases where up to 35% of the brand’s ad budget was spent on content inappropriate for the brand. This highlights the reality that even branding-focused advertisements are being placed in unsuitable environments.


An Advertising Environment that Considers Content Context is Necessary

This "storytime" content is not just a passing trend; it's a sensational narrative structure that is highly optimized for the YouTube algorithm. However, with harmful content like depictions of sex work, suicide, violence, hate speech, and fake news being circulated under this "story" umbrella, it has become crucial for brands to prioritize a safe advertising environment that considers content context as much as advertising efficiency.

To this end, PYLER monitors real-time ad placements and blocks ads from appearing on inappropriate content, providing a safe and high-performing advertising environment. PYLER is committed to helping brands connect with consumers in a safe and healthy content ecosystem.

‘AiD’: Helping Brands Regain Control Over Ad Placement

PYLER’s flagship solution, AiD, leverages AI to analyze the context of YouTube videos where brand ads are placed, blocking exposure to harmful or inappropriate content. The solution protects brands from being associated with adult content, hate speech, fake news, and fringe religious material that could damage brand reputation.

AiD: Solution That Protects Brand Trust

AiD by PYLER is a real-time brand safety solution that uses multimodal AI to automatically detect and block harmful content, improving both brand trust and ad performance. Built to meet global standards, it ensures brand messages are delivered in safe and effective environments.


PYLER’s New Standard for Brand Safety in Digital Advertising

Even as digital advertising becomes more sophisticated, many brands still face a fundamental challenge—the risk of ads appearing next to inappropriate content.

Violent, sexually explicit, politically or religiously biased, and hateful content can seriously damage brand perception. According to a global consumer survey, 64% of respondents said they lost trust in a brand after seeing its ad next to inappropriate content.

To solve this problem at the technological level, PYLER developed AiD, a real-time brand safety solution that automatically detects and blocks sensitive content in video-based ad environments—ensuring that brand messages are delivered in safe and effective contexts.


Fighting Fake News and Content Farming

One of AiD’s core priorities has been identifying and blocking fake news and manipulative content formats, such as clickbait or "storytime"-style videos that distort facts or spread false narratives.

On YouTube, this issue extends to “content farming” or “cyber re-uploaders”—channels that repurpose sensational material to exploit algorithms for visibility and revenue. When ads appear on these types of videos, brands can unintentionally become associated with misinformation or social division.

To prevent this, AiD excludes related content under its “Controversial Issues” category. Its AI models are continuously updated to respond to evolving content types and social issues, ensuring scalable and responsive brand protection.


Real-Time Filtering with Multimodal AI

AiD goes beyond basic keyword filtering. It uses multimodal AI, which analyzes both visual and textual elements of videos simultaneously. Through PYLER’s proprietary Vision Analyzer and Text Analyzer models, AiD classifies and blocks content related to Sexual content, Hate speech, Political or religious bias, Controversial or sensationalized “storytime” narratives etc.

AiD also supports custom filter criteria, allowing campaign-specific brand safety rules. As a result, advertisers can instantly assess content risk levels and ensure that their ads are placed only in safe, brand-aligned environments.


Proven Performance in the Field

AiD has already delivered tangible results in live campaigns:

  • 97% reduction in ad exposure on sensitive content

  • 15% improvement in ad performance (e.g., CVR)

  • 639% reduction in wasted ad spend on high-risk content

In one case, a brand reduced sensitive-content ad spend from 16.1% to just 2.1%, dramatically improving both efficiency and return on investment. AiD delivers the rare combination of trust protection and performance enhancement.


Built for Global Brand Safety Standards

AiD isn’t just functional—it’s also compliant with global brand safety guidelines.

PYLER is the first Korean company officially registered with the IAB Tech Lab, and AiD evaluates and filters content based on IAB’s globally recognized standards. These guidelines are used by the world’s top advertisers, making AiD a technically verified and transparent solution.


Globally Recognized Technology

AiD is powered by PYLER’s proprietary video AI, which has been internationally acclaimed:

  • CVPR 2022: 2nd place globally in Video AI (competing with Intel, Tencent, ByteDance, etc.)

  • CVPR & ICCV 2023: Research accepted by the world’s top AI conferences

  • 2024: Selected for both NVIDIA and AWS Global Startup Programs

PYLER continues to refine its technology in collaboration with global tech leaders.


Redefining the Basics of Advertising

In today’s digital landscape, advertising is no longer just about what you say—it’s about where you say it.

The context in which ads appear now directly impacts brand trust and consumer decision-making. AiD eliminates the need for manual review or guesswork. It enables advertisers to automatically avoid risky placements and run campaigns with both safety and efficiency in mind.

Now is the time for brands to make a strategic, technology-driven choice—to speak only in spaces that match their values. At PYLER we are committed to creating a safe space for brands to communicate confidently, backed by AI and built for the future.

Discover how PYLER's real-time video understanding helps brands like Samsung, BYD, and Hana Financial thrive.


At PYLER, we leverage our platform, video understanding AI, which deploys visual AI agents to ensure brand safety by verifying that ads are never displayed alongside inappropriate videos and placing them in more contextually relevant settings to protect brand value and enhance campaign effectiveness.

With the explosive growth of generative AI, the sheer volume of content uploaded to video platforms has skyrocketed. In such an environment, displaying ads next to content that’s not brand aligned increases marketing costs to target the correct audiences, but also presents a risk of negative brand impressions and potential reputational damage.

Video Understanding AI is crucial for effectively managing and validating content in an era of massive, high-speed uploads. When properly implemented, it becomes a key asset in safeguarding and enhancing a brand’s overall value.

Video content processing is significantly more complex than image or text processing, demanding substantial computational resources from preprocessing to inference. To handle this real-time influx of video content effectively, a high-performance pipeline utilizing optimized computing resources is essential.

In this post, we’ll discuss how PYLER addresses these challenges by adopting NVIDIA AI Blueprint for video search and summarization (VSS) in conjunction with NVIDIA DGX B200 systems. We’ll explore how we pair NVIDIA software and accelerated computing, with PYLER’s proprietary Video Understanding AI, to help ensure brand safety at scale.


PYLER Boosts Content Safety with NVIDIA AI Blueprint for VSS and NVIDIA AI Enterprise

    • State-of-the-art embedding models are essential for capturing rich contextual and semantic information from videos. PYLER integrates the NVIDIA NeMo Retriever  nv-embed-qa-1b-v2 model for minimal information loss during the embedding and captioning process.

  2. Scalable Infrastructure for training custom VLMs and Large-Scale Video Processing

    • NVIDIA DGX B200 accelerates custom VLM training and delivers up to 30x faster performance and best-in-class energy efficiency compared to its predecessor. 

    • With the immense volume of video content uploaded daily, GPU-based parallel processing is critical for scalability. PYLER utilizes VSS blueprint’s chunk-based parallel processing and GPU node expansion to dynamically distribute workloads and process video data in real-time. We look forward to enabling this on NVIDIA DGX B200 for inference.

  3. Flexible Verification and Search via RAG

    • PYLER rapidly searches and verifies vast amounts of video embeddings, leveraging Context-Aware Retrieval-Augmented Generation (RAG). This supports automated summarization, indexing, Q&A, and content validation tasks, significantly improving inference speed, accuracy, and context-awareness.


Expected Outcomes for PYLER

With these integrations, PYLER’s Video Understanding AI software can provide:

  1. Maximized Brand Safety

    • Precisely filter, classify, and recommend safe ad placements, ensuring ads never appear next to inappropriate or harmful content.

  2. Enhanced Brand Trust

If you're familiar with Korean YouTube content, you’ve likely already come across this phenomenon. 

These videos feature individuals sharing a wide range of tales, from humorous dating mishaps and strange encounters with colleagues to behind-the-scenes celebrity gossip and shocking accounts of specific events. Whether based on true experiences or creative fiction, these emotionally charged stories often perform well with the YouTube algorithm. However, this type of content can also harbor harmful elements such as fake news, sensationalized narratives, hate speech, explicit sexual experiences, and even stories about suicide attempts.

This raises the question: why is this "storytelling" format so prevalent and popular specifically on Korean YouTube, and what do advertisers need to keep in mind?


What is "Storytime" Content?

From the perspective of PYLER's brand safety solution, 'AiD', "storytime content refers to videos where the primary purpose is to convey true or fabricated stories and share gossip. Think of it as online storytelling. This style of sharing narratives has deep roots in Korean online culture, with many popular internet communities fostering a tradition of sharing personal accounts. On YouTube, common examples of content range from dating scandals, family conflicts, and workplace rumors to reviews of sex work establishments and accounts of failed suicide attempts – often prioritizing sensationalism over public interest.


Harmful "Storytime" Content: A Greater Risk in Korea

We searched for the same keyword—"grandmother"—on YouTube in four different languages: Korean (할머니), English (grandmother), Chinese (奶奶), and Japanese (おばあちゃん). The results revealed a stark contrast: when searched in Korean, the platform predominantly surfaced provocative "storytime" videos. In contrast, the English, Chinese, and Japanese search results mainly featured wholesome family content, informational vlogs, or cultural introductions.

This discrepancy goes beyond mere algorithmic variation—it highlights the overproduction of sensational, story-driven content in the Korean YouTube ecosystem. Narratives often revolve around sexual experiences, personal conflicts, or violent incidents, with creators prioritizing shock value and algorithmic optimization over ethical storytelling or content quality.

As a result, brands advertising in Korea face a significantly higher risk of having their ads placed alongside harmful storytime content compared to other markets. Over time, this misalignment can pose a serious threat to brand image and consumer trust.


Why is "Storytime" Content So Dominant in Korea?

While similar formats like "Storytime" or "Personal Confession" content trends exist internationally, they haven't achieved the same level of mainstream popularity and genre establishment as this "storytime" content in Korea. Korean "stories" have become a distinct genre due to a combination of factors: rapid audience engagement, immersive narrative structures, and narratives often based on anonymity.

  1. A Community Culture Familiar with Sharing Stories Online: For a long time, Korean online communities like DC Inside, Nate Pann, Blind, and Today's Humor have been active spaces for anonymous "story sharing." This established method of narrative delivery naturally extended to YouTube, making the consumption of video-based "storytime" content feel familiar and accessible.

  2. Influence of Broadcast Formats: Popular Korean talk shows like "Knee Drop Guru" and "Radio Star" frequently feature guests sharing personal anecdotes and experiences. This long-standing exposure to spoken storytelling in mainstream media has created a viewing culture that readily accepts "stories from good talkers" as engaging content.

  3. Anonymity and Third-Party Storytelling: Unlike direct first-person confessions, Korean "storytime" content that relays or reports others' stories in the third person is also widely consumed. Reconstructing events, narrating urban legends, and summarizing incidents can generate high levels of immersion, making it easy to diversify content formats.

  4. Low-Cost, High-Engagement Format Combined with Algorithms: "Storytime" content can often be produced simply with text-to-speech narration, without the need for cameras or extensive editing. Its emotionally engaging narrative structure and clickbait-style titles align very well with the YouTube algorithm. This allows creators to achieve high view counts with relatively low production costs.


What About Overseas?

While "Storytime" content exists in English-speaking countries like the United States, its nature and consumption patterns differ.

Why Should Brands Pay Attention to This Phenomenon?

This "storytime" content presents a high-risk environment for advertising. However, many brands are currently running ads without fully understanding these risks.

Key Risks:

  • Risk of Context Distortion: When a brand's advertisement appears within content dealing with personal misfortunes or social conflicts, it can lead to negative associations between the brand and those issues.

  • Emotional Mismatch: Exposure to content featuring topics like sex work, suicide, or hate speech can severely damage a brand's image and reputation.

  • Decreased Credibility: The truthfulness of "storytime" content is often questionable, making it highly susceptible to fake news or defamation. Appearing alongside such videos can erode trust in the brand itself.

In fact, PYLER's analysis of advertising campaigns has revealed cases where up to 35% of the brand’s ad budget was spent on content inappropriate for the brand. This highlights the reality that even branding-focused advertisements are being placed in unsuitable environments.


An Advertising Environment that Considers Content Context is Necessary

This "storytime" content is not just a passing trend; it's a sensational narrative structure that is highly optimized for the YouTube algorithm. However, with harmful content like depictions of sex work, suicide, violence, hate speech, and fake news being circulated under this "story" umbrella, it has become crucial for brands to prioritize a safe advertising environment that considers content context as much as advertising efficiency.

To this end, PYLER monitors real-time ad placements and blocks ads from appearing on inappropriate content, providing a safe and high-performing advertising environment. PYLER is committed to helping brands connect with consumers in a safe and healthy content ecosystem.

PYLER Secures KRW 22 Billion in Series Funding to Advance AI Brand Safety Solutions

Trusted by top brands, PYLER aims to lead globally in video understanding and ad transparency.


Recognized for Its Cutting-Edge AI Brand Safety Technology

PYLER, a leading provider of AI-powered brand safety solutions, has successfully secured KRW 22 billion in its latest series funding round. Key investors include Stonebridge Ventures, Korea Development Bank, SV Investment, and KT Investment—underscoring strong confidence in PYLER’s technology and growth potential.


‘AiD’: Helping Brands Regain Control Over Ad Placement

PYLER’s flagship solution, AiD, leverages AI to analyze the context of YouTube videos where brand ads are placed, blocking exposure to harmful or inappropriate content. The solution protects brands from being associated with adult content, hate speech, fake news, and fringe religious material that could damage brand reputation.

With millions of new videos uploaded to YouTube every day, manual review is no longer feasible. In this context, investors recognized AiD’s value in empowering advertisers with greater control and visibility over where their ads appear.


Brand Safety Directly Impacts Consumer Trust and Behavior

According to a joint report published in January by PYLER and the Korea Broadcast Advertising Corporation (KOBACO), 89.5% of consumers said brand safety is important, while 96% stated they would not purchase from advertisers who neglect it. These figures clearly show that brand safety plays a critical role in shaping both consumer trust and purchasing behavior.

AiD: Solution That Protects Brand Trust

AiD by PYLER is a real-time brand safety solution that uses multimodal AI to automatically detect and block harmful content, improving both brand trust and ad performance. Built to meet global standards, it ensures brand messages are delivered in safe and effective environments.


PYLER’s New Standard for Brand Safety in Digital Advertising

Even as digital advertising becomes more sophisticated, many brands still face a fundamental challenge—the risk of ads appearing next to inappropriate content.

Violent, sexually explicit, politically or religiously biased, and hateful content can seriously damage brand perception. According to a global consumer survey, 64% of respondents said they lost trust in a brand after seeing its ad next to inappropriate content.

To solve this problem at the technological level, PYLER developed AiD, a real-time brand safety solution that automatically detects and blocks sensitive content in video-based ad environments—ensuring that brand messages are delivered in safe and effective contexts.


Fighting Fake News and Content Farming

One of AiD’s core priorities has been identifying and blocking fake news and manipulative content formats, such as clickbait or "storytime"-style videos that distort facts or spread false narratives.

On YouTube, this issue extends to “content farming” or “cyber re-uploaders”—channels that repurpose sensational material to exploit algorithms for visibility and revenue. When ads appear on these types of videos, brands can unintentionally become associated with misinformation or social division.

To prevent this, AiD excludes related content under its “Controversial Issues” category. Its AI models are continuously updated to respond to evolving content types and social issues, ensuring scalable and responsive brand protection.


Real-Time Filtering with Multimodal AI

AiD goes beyond basic keyword filtering. It uses multimodal AI, which analyzes both visual and textual elements of videos simultaneously. Through PYLER’s proprietary Vision Analyzer and Text Analyzer models, AiD classifies and blocks content related to Sexual content, Hate speech, Political or religious bias, Controversial or sensationalized “storytime” narratives etc.

AiD also supports custom filter criteria, allowing campaign-specific brand safety rules. As a result, advertisers can instantly assess content risk levels and ensure that their ads are placed only in safe, brand-aligned environments.


Proven Performance in the Field

AiD has already delivered tangible results in live campaigns:

  • 97% reduction in ad exposure on sensitive content

  • 15% improvement in ad performance (e.g., CVR)

  • 639% reduction in wasted ad spend on high-risk content

In one case, a brand reduced sensitive-content ad spend from 16.1% to just 2.1%, dramatically improving both efficiency and return on investment. AiD delivers the rare combination of trust protection and performance enhancement.


Built for Global Brand Safety Standards

AiD isn’t just functional—it’s also compliant with global brand safety guidelines.

PYLER is the first Korean company officially registered with the IAB Tech Lab, and AiD evaluates and filters content based on IAB’s globally recognized standards. These guidelines are used by the world’s top advertisers, making AiD a technically verified and transparent solution.


Globally Recognized Technology

AiD is powered by PYLER’s proprietary video AI, which has been internationally acclaimed:

  • CVPR 2022: 2nd place globally in Video AI (competing with Intel, Tencent, ByteDance, etc.)

  • CVPR & ICCV 2023: Research accepted by the world’s top AI conferences

  • 2024: Selected for both NVIDIA and AWS Global Startup Programs

PYLER continues to refine its technology in collaboration with global tech leaders.


Redefining the Basics of Advertising

In today’s digital landscape, advertising is no longer just about what you say—it’s about where you say it.

The context in which ads appear now directly impacts brand trust and consumer decision-making. AiD eliminates the need for manual review or guesswork. It enables advertisers to automatically avoid risky placements and run campaigns with both safety and efficiency in mind.

Now is the time for brands to make a strategic, technology-driven choice—to speak only in spaces that match their values. At PYLER we are committed to creating a safe space for brands to communicate confidently, backed by AI and built for the future.
