Tonho is my personal macOS app, built for a single user: me. It puts in one place the finances read through Pierre, the monthly budget and planned purchases, my sole-proprietor (MEI) paperwork, a diet based on seasonal fruit, picks for films, series, books and games, an agent for my websites and a key vault in the Keychain. Three routines run on their own through launchd, and the tonho-contas MCP lends my accounts to other LLMs, which only write with my approval. The AI runs through Claude Code, isolated and with only the tools each screen needs, and the numbers on screen come straight from the APIs, never from the model's text. I started Tonho in October 2026, in Swift, and the code is not published yet.
