## Definition

Tolaria is a free, open-source macOS and Linux desktop app for managing Markdown-based knowledge bases. Notes are plain files — portable, git-versioned, offline-first — with a Notion-style block editor and built-in MCP server for AI agent access.

[Luca Rossi](https://refactoring.fm/p/introducing-tolaria) of the Refactoring newsletter (170K subscribers) launched Tolaria on [April 22, 2026](https://github.com/refactoringhq/tolaria/releases). Built on Tauri, React, and Rust with 100% AI-written code across ~100K lines and 3,000+ tests, it reached 246 HN front-page points and 2,900 GitHub stars within 24 hours of release.

## Analogy

Think of it as Notion's UX grafted onto your local file system, with Git as the sync layer.

## Why it's emerging now

AI agents need persistent, structured context storage. Tolaria launched April 22, 2026 as the first open-source knowledge base designed explicitly around this: a bundled MCP server lets Claude Code and Codex CLI read and write your vault natively. Luca Rossi's 170K-subscriber newsletter amplified day-one adoption to 2,900 GitHub stars.
