exobooks

exobooks is a ledger system of record for bookkeeping agents: the books live in exobooks, a double-entry ledger with any number of ledgers and currencies and a versioned history of every change, and the bookkeeping intelligence is your own AI agent, working the books from outside through an HTTP API. As of November 2026 it is in early development. A free local server, which runs on your own machine, is available at https://github.com/exobooks/exobooks: with it an agent can create ledgers, accounts and transactions and read back the chart of accounts, and everything in it will change. The hosted service at exobooks.ai is not open to users yet.
