I Built My Own J.A.R.V.I.S. — A Local, Privacy-First Multi-Agent AI Assistant

I wanted a personal AI assistant. Not a chatbot. Not a copilot. Something that actually does things — controls my desktop, reads my screen, talks to my smart home, answers questions in Finnish or English, and never, ever sends my data to a server I don’t control.

The cloud options are good. They’re not mine.

So I started building one.

This post is the architecture document for that project. It’s a work in progress — the docker-compose is ready, the Ollama instance is running, and the first agent is next. I’m writing this because the design decisions are interesting, and because someone else might want to build the same thing.
