# AllSquare

> AllSquare splits shared expenses in groups: who paid, who owes whom, recurring bills, and settling up. People connect AI tools to AllSquare with OAuth and approve read or write access.

## Command line (recommended for coding agents)

- [CLI guide](https://allsquare.app/docs/cli): install with `npm install -g allsquare`, sign in with `allsquare auth login`
