Advertiser FAQ
Questions from advertisers
How much does it cost to advertise to AI users?
You set your own bid per 1,000 impressions, starting from $2.00, and buy in blocks of 1,000 impressions. 10 blocks at $2.00 is $20. There is no minimum contract and no agency.
Where exactly does my ad appear?
Your line appears inside ChatGPT, Claude and Gemini, right under the user's message, while the model is thinking. It's the one moment the user is looking at the screen and waiting.
How are impressions allocated between advertisers?
Every active campaign is eligible to show, weighted by bid. A $5 bid earns roughly 2.5x the impressions of a $2 bid.
How long does campaign review take?
Campaigns are reviewed before going live, usually within 24 hours. You can edit your ad while it is pending review.
What can't I advertise?
No adult content, gambling, weapons, malware, misleading claims, or anything illegal. We reject ads that impersonate other brands.
