Local-first, AI-native bookkeeping
Your books, in plain files.
Your AI, the one you already use.
The box that holds your data should be simple, sturdy, and cheap.
“AI-native” doesn’t mean entries appearing behind your back when you talk to a bot. It means being easy to use — for AI and for people.
—— That's why we built it.
