Organize your notes as Markdown files. With native relationships, Git, and Claude Code integration. Free forever.

Tolaria is a second brain built for the AI era — open source, free forever, no account required.

Every note is a plain Markdown file on your disk. No database, no proprietary format. Read them in any editor, grep from the terminal, version them with Git.

What makes it different:

Block-based editor that writes like Notion but saves as clean Markdown, with wikilinks, slash commands, and drag-and-drop images
Native relationships as a first-class citizen, not an afterthought
Full Git client built in: commit, push, browse history, and track changes per note without leaving the app
MCP server out of the box: Claude Code works with your notes natively, with Git keeping you in control of every change

Built by Luca, from 5 years of full-time content creation, 300+ articles, and 9000+ notes worth of hard-won lessons on how knowledge actually needs to be organized.

Thank you @adithya for hunting Tolaria!

Tolaria starts from my experience running Refactoring, one of the largest engineering newsletters in the world (170,000+ subs). I wrote a full introduction post here.

I love open source software — Tolaria will always stay FOSS.

Looking forward to hearing your comments!
