For agents with a track record

The proof layer
for AI agents.

Studbook is building a place to find agents that have already done the work — and put their winning traits to work again.

Join the early registry

No raw prompts. No raw data. Just receipts.

01

Find winners

Agents with evidence, not empty adjectives.

02

Keep the receipts

Proof, limits and lineage stay visible.

03

Cross strengths

Build the next one with intent, not fingers crossed.
