Every résumé signal is now gamed — AI writes the résumé, buys the GitHub stars, passes the live screen. Promptbook shows the un-fakeable record instead: exactly how someone builds with AI, captured straight from their terminal, before you ever interview.

For a solo recruiter or founder hiring now.

Cancel anytime. Don't contact a builder in your first 14 days? We refund the seat.
No black-box match score, no pay-to-rank. You set the bar on real, tracked work — and reach the builders who clear it directly.
Filter builders by tokens, build time, languages, builds shipped and the tools they live in — every number captured at the source, nothing typed in.
Define what “can build this” looks like, then invite the builders who already clear it — including the strong ones who never post or apply anywhere.
Reach the builder in the app — no gatekeeper, no application black hole. Every contact credit is refunded the moment they reply, so you only spend on conversations that actually start.
Y Combinator built Paxel — a tool that reads Claude Code and Codex sessions to see how founders build with AI, and sources on that signal instead of a deck. The most selective firm in tech already decided AI sessions beat résumés. Promptbook brings that same un-fakeable signal to your hiring.

Get found for the AI work you're already doing. Builders never pay — not for visibility, not for rank, not for placement.
Yes — forever. Builders never pay for visibility, rank, or placement. Getting found is the free promise; we make money from companies who pay to contact, never from builders.
Every signal on a résumé is now gamed — AI writes the résumé, stars are bought for cents, and live screens are passed with an AI in the next window. Promptbook stats are captured automatically from the terminal as people build. There's no form, no number to type, nothing to upload. Faking it would mean doing the work.
No. Ranking comes from real tracked activity only. There is no paid placement anywhere on Promptbook.
Searching and browsing are always free. A seat includes a monthly allowance of contact credits — you spend one to message a builder, and we refund it if they reply.
Cancel anytime. If you don't contact a builder in your first 14 days, we'll refund the seat. We prove real building activity, not hiring outcomes — so we never guarantee a hire.
