atlas-mind

Atlas Mind is a self-hosted, git-native knowledge base for keeping notes as plain files in a private git repository. It is built around the idea that the user owns the data and the engine, and it presents itself as a self-hosted Notion alternative and a way to publish an Obsidian-style vault that remains in the user’s own repository.

Its core features include a live, force-directed knowledge graph, Markdown as a first-class format, and support for previewing HTML decks, PDFs, and Word .docx files inline. Atlas Mind also exposes an MCP endpoint with twenty-two tools for AI assistants, covering actions such as reading, writing, mapping, rewinding, auditing, searching, and traversing note links. The page also describes activity features that record changes as git commits, with attribution for author, date, and whether an AI made the edit, plus journal, constellation, and health views for activity, contributors, obsolescence, and contradictions. It also includes inbox handling for triaging incoming items into the knowledge base.

The product is intended for use with AI clients, including Claude, and its “demo” runs entirely in the browser. The rest of the system is described as a single Python HTTP server on the standard library with no database, no third-party network calls, vendored fonts and libraries, and plain JSON on disk for accounts and share links. The page also says that shared mirrors stay read-only and that deletes are reversible.

Atlas Mind is offered as self-hostable software under the AGPL-3.0 license. The entry also refers to GitHub and a live demo, and it frames the tool as a Markdown wiki and a knowledge base rather than a hosted notes service.
