Trendos launches Ad Radar to track sponsored ChatGPT placements

Trendos has moved AI search reporting past organic mentions and into paid placement tracking. The company launched Ad Radar on May 20, 2026, adding a feature to its AI search visibility platform that shows which competitors are advertising inside ChatGPT responses and how those sponsored placements surface in real time.

The launch lands at a moment when AI answers are starting to look less like a pure discovery layer and more like a media channel. Trendos, which Tesonet launched in March 2026, already tracks AI search visibility across ChatGPT, Google AI Overview, and Gemini. Tesonet says the platform covers 13-plus regions and monitors historical and real-time data for more than 2.5 million brands, giving Ad Radar a wide base of coverage rather than making it a narrow add-on.

That matters because the metrics around AI search are multiplying fast. Brands have been watching organic mentions, citation share, and sentiment. Ad Radar adds a new layer: sponsored inventory inside conversational results. For marketers and agencies, the question is no longer only whether ChatGPT names a brand, but whether a rival has bought attention inside the answer itself, how often that placement appears, and how the message is framed when a consumer is already reading a response.

OpenAI’s own ad test helps explain why the market is moving this way. The company began testing ads in ChatGPT in the United States on February 9, 2026, starting with logged-in adult users on the Free and Go tiers. OpenAI said the placements would not influence answers and would not expose conversations to advertisers. By March 26, the company said it was seeing no impact on consumer trust metrics and low dismissal rates, then on May 7 it said it planned to expand the pilot to the United Kingdom, Mexico, Brazil, Japan, and South Korea.

The infrastructure for measurement is arriving alongside the ads themselves. OpenAI’s developer documentation now describes a JavaScript conversion pixel, a conversions API, and an Advertiser API for measurement, programmatic ad creation, and performance monitoring. That gives third-party intelligence vendors a clearer signal that paid visibility in AI search is becoming trackable, comparable, and reportable.

Adthena’s numbers underline the scale of the format shift. The ad-tech company said it was tracking more than 50,000 daily ChatGPT ad placements across 600-plus advertisers, with ads appearing inline in responses and clearly labeled Sponsored. Trendos’s Ad Radar now enters that same conversation from the monitoring side, making it easier to see how paid visibility is spreading inside answer engines and why competitive intelligence for AI search is becoming its own category.
