Arbos

Your projects, run as agents.

Arbos gives every project one long-lived agent that delegates the work, talks with you in full duplex, and keeps its state in files you can read, commit, and rewind.

The Arbos desktop app: a project tab, the main chat asking two workers to write files, both workers running in the right-hand project panel.
How it works

One agent per project. It runs for as long as the project does.

01

It delegates

The main chat never blocks. You keep talking; it hands each piece of work to a smaller agent with the notes and pointers it needs, then folds the results back in.

02

You talk to it

Call your project from the desktop or your phone. Both sides speak and listen at the same time. Interrupt it mid-sentence, and it still hears you while it speaks.

03

State lives in files

Agents, plans, notes, and subscriptions are plain files in .arbos/. Read them, commit them with git, and rewind to any saved point.

Get started

Download, paste a model key, open a folder.

Arbos talks to any model through OpenRouter by default; OpenAI-compatible endpoints work too. Everything else is on the Install page.
