Free โ no card, no download
WarmBook's coach will interview you about your business, turn your 90-day goal into daily numbers, and give you a morning briefing every day โ free, permanently. No credit card, nothing to install. It runs inside the Claude you already use.
What's free, what isn't
No feature is time-limited โ the free side stays free. What you're paying for is the part that compounds: your database, and the full method behind the coaching.
Start free
You'll need a Claude account (claude.ai โ the free plan works). WarmBook connects to it the same way any tool does.
In Claude: Settings โ Connectors โ Add custom connector.
https://api.warmbook.app/mcp โ then click Connect.
WarmBook's sign-in page opens. You don't have a key yet, so click the "No key? Try the free tier" button underneath. That's it โ you're in.
Start a new chat and say "hi". The coach opens with the interview โ answer honestly and you'll walk away with a plan, not a demo.
Straight answers
No. There's no countdown and no card on file. The free side stays free โ if it's all you ever use, that's fine.
WarmBook isn't an app you log into โ it's a coach that plugs into the AI you already use, so your database can live on your machine instead of our servers. Claude can create files, which is what builds your Book on the paid side. ChatGPT works for the coaching, but it can't create files, so it can't build the Book.
It never reaches us. On the paid side, your Book is a file on your own computer; our server only sends coaching content to your AI when it asks. Cancel someday and your data stays with you.
No โ and be suspicious of anything that says it is. WarmBook is a coach and a system for the relationships you already have. It works if you do.
