A free, open-source second brain — notes live as local Markdown files with native Git history and built-in AI agents, no proprietary database.

Tolaria stores every note as a plain Markdown file with YAML frontmatter on disk — no database, no lock-in. A block-based editor adds slash commands, wikilinks, and media previews on top, while a fully integrated Git client commits and syncs the whole vault across devices.
It pairs a Notion-style editor with files you actually own, plus version history for free — notes you can diff, branch, and roll back like code.
Free forever, open source under AGPL-3.0-or-later. No account required.
