A companion to the Jawz Loop
Your private investment memory.
You run the Jawz Loop. Rumo remembers what you decided, why you decided it, and what changed since — so every run builds on the last instead of starting cold. It lives in plain files on your own computer. Nothing is uploaded to anyone’s servers, not even ours.
Free · No account · Your files stay on your machine · Needs Claude Desktop (Mac or PC)
Two layers, one loop
Jawz is the public framework and the live market read. Rumo is the private record only you own. They work in the same conversation.
Jawz — public
The framework and the market read
The Jawz Loop and live market context. Jawz stays stateless about your book on purpose — it supplies the thinking and the prices, it never holds your positions.
Rumo — private
The record that compounds
Your book, theses, decisions, and reviews — kept as plain files on your machine. This is what lets Chapter 4 retrospectives actually look back, because the history is really there. It starts empty: you log your book and decisions first, and each month of history makes the retrospectives sharper.
Rumo is two pieces, one vault
One records, one shows it back — both reading and writing the same folder of plain files on your machine. You need both for the full experience.
1 · The extension — records
Rumo for Claude Desktop rumo.mcpb
Talk to Claude about your portfolio; the extension logs your holdings, theses, and decisions, and refreshes prices & the macro read. It creates and owns your vault — this is the half that writes.
Runs inside Claude Desktop
2 · The app — views
Rumo desktop app .dmg / .exe
A read-only window onto your book: NAV, performance, factor exposure, and the regime tilts. It reads the same vault the extension records into — this is the half that shows it back.
A native macOS / Windows app
The extension writes, the app reads. Extension only → you can record and ask Claude, but there’s no dashboard. App only → it opens to an empty book. Both, pointed at the same vault, is the working setup.
What Rumo keeps
- Decisions & theses
Why you hold what you hold, what would change your mind, every decision you logged — recallable next session, not lost to the chat history.
- Your book, valued
Positions, NAV, and how your exposure is spread across factors — computed from the prices Jawz supplies, kept current as you refresh.
- Performance over time
A real, cash-flow-adjusted return curve across months — the honest picture of how the book has actually done, not just where it stands today.
- Proposals you review
The AI suggests; you accept or reject. Only what you approve becomes durable memory. Nothing is canonized behind your back.
Yours, and only yours
Everything lives in plain Markdown and JSON files in a folder you control — your computer, or your own iCloud or Dropbox. There’s no account, no subscription, and nothing is sent to a Rumo server, because there isn’t one. The AI reasoning runs on your own Claude.
Where it runs
Both pieces need Claude Desktop on a Mac or PC, because your files live on your machine. (Jawz itself works anywhere — Claude, ChatGPT, any MCP client — but Rumo’s local-first design means the desktop pieces are required.)
Get Rumo
Both pieces are free, open downloads from the Rumo repo. Easiest path: let your AI walk you through it.
Easiest setup
Let your AI set it up with you
Copy the setup guide, paste it into Claude or ChatGPT, and ask it to walk you through installing both pieces — step by step, answering your questions as you go.
1 · Extension — records
rumo.mcpb
Install in Claude Desktop (Settings → Extensions → drag it in). It creates your vault and starts recording.
Download the extension →2 · App — views
Rumo desktop app
The read-only dashboard for your book. Pick your platform:
- Install the extension in Claude Desktop and pick a vault folder — and add the Jawz connector the same way (paste
https://jawz.ai/api/mcp), so live prices and the macro read work. Rumo keeps your book; Jawz says what things are worth. - Record something — just tell Claude what you hold (“set up my portfolio: 2 BTC, 30 ETH, 150 shares of Rocket Lab”). Your vault now has data.
- Install the app and open it — it reads the same vault and shows your NAV, performance, factors, and regime tilts.
