Atlas Mind

It's your mind, not someone else's.

Notion, and every hosted notes app, ask you to pour your thinking into their structure, on their servers, in their format. You rent the space; they hold the keys. Atlas Mind inverts that: your knowledge is plain files in your own git repository, served by an engine you can read line by line and throw away without losing a single note. Your AI comes to your library through an open protocol; it never pulls your brain into its own.

Own the data. Own the engine. Own the mind.

Atlas Mind is a self-hostable wiki / knowledge base engine, and an external brain you share with your AI. It serves a single-page viewer from a folder of documents (a mind), keeping the engine (the code) cleanly decoupled from your content (your notes, in their own git repository). Built on three ideas:

• Multi-format, not just Markdown. Markdown is first-class (rendered, linked, searched). Standalone HTML decks and dashboards, PDFs, and Word .docx are previewed inline, converted to readable HTML in your browser, nothing uploaded anywhere.
• AI-native. It exposes an MCP endpoint (twenty-four tools to read, write, triage, map, rewind and audit your mind), and atlas init scaffolds the conventions (AGENTS.md, agents/, ai-sessions/) so an assistant knows how to use your mind.
• Lightweight & self-contained. A single Python HTTP server on the standard library: no database, accounts and share links live as plain JSON on disk, frontend libraries and fonts are vendored. A running instance makes no third-party network calls: your mind never leaves your disk, and nothing you write trains anyone's model.

It is not a multi-tenant SaaS, a real-time collaborative editor, or a plugin marketplace. One focused mind per instance, fully yours.

Install

Installing puts a self-contained atlas command on your PATH (the viewer assets ship inside the package, no separate download).

# Easy way: uv or pipx (isolated env, no virtualenv to manage)
uv tool install atlas-mind        # or: pipx install atlas-mind
atlas serve ~/my-mind

# Run once without installing, straight from PyPI
uvx atlas-mind serve ~/my-mind    # or: pipx run atlas-mind serve ~/my-mind

# With pip (a virtualenv is recommended)
pip install atlas-mind

Requires Python >= 3.11 and a git repository for your content.

Quick start

atlas init ~/my-mind     # scaffold a mind: atlas.toml, example docs, AGENTS.md, git init
atlas serve ~/my-mind    # build once if needed, then serve on http://127.0.0.1:8765

init is never destructive (it refuses a non-empty directory without --force and keeps any file already present). serve listens on 127.0.0.1:8765 with authentication off by default. To produce the static viewer without serving: atlas build ~/my-mind [--offline].

See atlas --help for all commands (user, token, share, deploy).

Use it with your AI (MCP)

Atlas Mind is designed to be the external memory your assistant reads and writes. On a deployed instance, each user mints their own token from the web UI — Settings → Tokens — boun
