I'm building Rhizio — a second brain that tends itself

I keep losing my own thoughts. An idea lands in a notes app, an article gets bookmarked and never reopened, a half-formed question goes into a message I send to myself, a goal I set in January never gets looked at again. It's all mine, but none of it is in one place — and the more I collect, the heavier and less useful the pile gets.

So I've been building Rhizio: my attempt at a fix for the scattered mind.

The core loop comes down to a few moves.

Drop a thought, let Rhizio sort it out. Paste some text or a URL. It reads what you gave it, drafts proper wiki pages from it, and threads them into everything else with [[wikilinks]]. You just look over the draft and approve. The whole point is to stop stopping to take notes — you offload the raw thought and let the system do the tidying.

Ask your own brain. That thing you read months ago and can't quite place? Rhizio can. You ask in plain language and it answers out of your wiki, with citations pointing back to the exact pages. Less like search, more like talking to everything you've already thought.

Goals and rituals. It's meant to be a compass, not just an archive. You lay goals out as a tree — life areas down through yearly, quarterly, weekly — then log progress in plain sentences, and Rhizio files it onto the right pages. It writes your weekly and monthly reviews for you, and runs a quiet health check that flags pages going empty or drifting loose. Bit by bit, the mess becomes a system.

See how it all connects. There's a graph of the links between your notes, and a dashboard for goals, streaks, and momentum — the noise in your head turned into something you can stand back and actually look at.

Your key, your data. It runs on your own API key — OpenAI, Anthropic, Google, or a local Ollama — and everything lives as plain git + markdown in a repo that's yours. Export it whenever. Private by default.

The newest piece is the social layer. You can ask for access to someone else's brain, and if they say yes, you chat inside their wiki — with your own key, seen through their notes. That's the moment the mycelium metaphor finally clicked for me: not just my own pile of thoughts, but a network of minds feeding each other.

Because I've stopped believing a good second brain is a tidy container. It's a living network — something that grows like a fungal web underground: spreading, branching, joining things up. You bring the thought; it grows the roots.

Rhizio is real and running. Now I'm going to start testing it for real — living in it day to day and sharpening as I go: quicker answers, an easier first run, better handling of long conversations, mobile. It's a work in progress, and honestly that's the best part. I'm building the tool I always wished I had for my own scattered head, and slowly watching it turn into one.
