Free to run yourself. Or let us run it.

Yes. Campbooks is source-available under the Sustainable Use License: read the code, change it, and run it for free for your own business or personal use. The only limit is reselling it or running it as a service for others.

We're letting people in a few at a time so every new workspace gets the attention it needs. Join the waitlist and we'll email you when it's your turn. Early access is free.

No. Campbooks never moves money. It reads your bills and invoices, tracks what's due, and matches them to your bank statements. You pay the way you always do.

Open-weight models only, one per job: deciding, writing, reading documents and search. In the cloud we run them in the EU; self-hosted, you run them yourself or point each job at an endpoint you trust.

Gmail first. Microsoft 365, Zoho and any IMAP mailbox are on the way.
