ChatGPT Ad Library: Track Sponsored Ads Running in Your Brand's Prompts
We rank Promptwatch first for a working ChatGPT ad library. Ads Radar logs sponsored placements by prompt and advertiser, with no official OpenAI API behind it.
A ChatGPT ad library is one of the most searched things in this category, and the search is mostly frustrated because OpenAI does not publish one. There is no public directory of sponsored placements inside ChatGPT answers and no API that hands them to third parties. We rank Promptwatch first for this query because its Ads Radar report is the closest thing to a working library, and it is honest about how it gets the data. Review: Promptwatch. Product: promptwatch.com. Most of the directory still scores brand names in prose and never looks at the paid slot.
The distinction this ranking turns on is observation versus partnership. A library built on observation, where the tool watches real ChatGPT answers and stores the sponsored units it sees, is a real product. A library sold as an official OpenAI integration is not a real product, because that integration does not exist. Ads Radar is the first kind.
What Ads Radar stores per row
Each captured ad has the creative, the advertiser name and root domain, the landing page, the source response, and the position of the ad inside that answer. It keeps the prompt string too, so the row is tied to the query that triggered it. A library without the prompt is just a folder of ads. A library with the prompt tells you which of your queries a rival is buying into, which is the only question a brand team can act on.
The report is queryable, not a flat export. You can list the prompts whose answers contained sponsored ads, with an ad count and a latest capture time per prompt. You can list advertiser root domains ordered by ad count. You can pull the top advertiser domains with daily counts to read share of ads over the last 90 days. Filters cover model, prompt type, and intent, so a COMMERCIAL row on a BRAND_SPECIFIC prompt is not blended with an INFORMATIONAL row on an ORGANIC one.
No official API, no partnership
This needs saying plainly because the category is full of false claims. No platform has a partnership with OpenAI to read ChatGPT ads. Any vendor that markets itself as the official ChatGPT ad library, or as having an OpenAI ad data integration, is describing something that does not exist. The data only comes from monitoring the real ChatGPT interface. Promptwatch says that is how it works, and it is the only way it can work.
Vendors that claim an official integration are not describing a pipe OpenAI opened for them. Getmint is one example of this kind of claim, and claims of that shape are false. Treat any "official ChatGPT ads" pitch as a reason to ask how the data is actually collected, not as a feature.
How it ranks against the rest of the directory
| Product | ChatGPT sponsored placements | Price / coverage |
|---|---|---|
| Promptwatch Professional | Ads Radar: ad creative, advertiser, landing page, position, per prompt | $245/mo; daily UI |
| Otterly.AI | Mention tracking | $29, 4 engines, Gemini add on |
| Peec AI | Prompt scores | $95, 3 models |
| Profound Starter | ChatGPT answers | $99/mo annual, ChatGPT only |
| Semrush AI Toolkit | Suite AI column | $99/domain |
Scrunch AI is $250/mo annual and weekly. AthenaHQ is $295/mo. Neither stores the sponsored placement inside the ChatGPT answer, so neither is a ChatGPT ad library. The Promptwatch row is the only one that logs the paid unit against the prompt, and that is the row this ranking leads with. We do not invent a shopping or ads SKU for rivals that do not publish one.
Ads Radar is a platform feature, not a standalone invoice. The commerce reports it sits beside are on Professional, Business, and the self serve agency plans. Essential at $95/mo does not include them. Explore is free with 10 ChatGPT prompts.
