Reach people while they use ChatGPT, Claude and Gemini without enterprise minimums. Waitnai shows one sponsored line during the moment of peak attention: while the AI is thinking.
Updated October 17, 2026
Why AI chat is the new premium ad slot
Developers, founders, students and knowledge workers spend hours a day in AI assistants. Every prompt creates a few seconds where the user is looking at the screen and waiting. There's no feed to scroll and nothing else competing for attention.
That's what makes AI chat advertising different from banners: your message is the only thing to read, at the moment of highest focus.
What a campaign looks like
- One line of copy, up to 64 characters, plus your sponsor name and an optional square icon.
- Your CPM bid: $2.00, $2.50, $5.00 or custom. Every active campaign is eligible to show, weighted by bid.
- Blocks of 1,000 impressions, paid up front from your wallet. Unserved impressions are refunded if you stop.
- Human review within 24 hours, then live on ChatGPT, Claude and Gemini.

Brand safety and privacy
Your ad never appears inside AI output and is never generated by AI. Every campaign is reviewed by a person before going live, and we reject misleading, adult, gambling and impersonation ads. Because the extension can't read chats, there's no invasive targeting, just a high-intent, tech-savvy audience.
Frequently asked questions
Can I advertise on ChatGPT without a big budget?
Yes. Waitnai is self-serve: you choose your bid per 1,000 impressions starting at $2 and buy in blocks of 1,000 impressions, so you can start with $20.
Where exactly does my ad appear?
Inside ChatGPT, Claude and Gemini, directly under the user's message while the model is generating a reply. It's one text line with your brand name and an optional icon.
How is this different from ChatGPT's own ads?
You don't need a sales call or a large minimum commitment, you control your bid directly, and you can launch in minutes. Your ad reaches people across three AI assistants, not just one.
How are impressions counted?
An impression is counted once the line has actually been displayed during generation, with rate limits and fraud checks per user. Clicks are counted once per impression.
How do I pay?
Top up your wallet with Whop checkout (card, Apple Pay, Google Pay). Campaigns are paid from the wallet, and any unserved impressions are refunded if you stop a campaign. Prefer invoicing? Email advertisers@waitnai.com.
