First public registry catalogs every ad running inside ChatGPT
ChatGPT Ad Library claims to be the first public registry of sponsored ads inside ChatGPT, tracking 11,103 advertisers, 415,289 placements and 43,410 creatives across 970 niches. Each ad is traced to the exact prompt that triggered it. OpenAI publishes no ad transparency center for its growing ad business, so this crowdsourced catalog is filling that gap for marketers who want to spy on competitor creative and lift CTR.
