## About longbook

longbook is a memory for your financial commitments: subscriptions, insurance, rent, loans and every other payment that comes back. It runs on iPhone and Mac and keeps its records as plain files in your own iCloud.

The next payment stays in view on the iPhone widget and in the Mac menu bar. Your AI can read your longbook and update it through longbook's MCP server, and every change it makes shows in Changes, to keep or undo.
