Tolaria

What is Tolaria?

Tolaria is a free, open-source desktop app that turns a folder of plain Markdown files into a fully navigable second brain. Every note stays as a standard Markdown file with YAML frontmatter, so there is no proprietary database or lock-in and any external tool, editor, or terminal can read the same files directly. Built with Tauri, React, and Rust, Tolaria pairs a block-based editor with native Git version control and a built-in MCP server, letting coding agents like Claude Code and Codex inspect and edit the vault directly. It runs on macOS, Windows, and Linux, requires no account or subscription, and is distributed under the AGPL-3.0 license.

Key Features

• Plain Markdown Storage

  Notes are stored as standard .md files with YAML frontmatter, avoiding proprietary formats or hidden databases so any external tool can read them.

• Native Git Integration

  Every vault behaves like a Git repository, giving users built-in version history and sync without extra plugins or services.

• Built-in MCP Server

  An embedded Model Context Protocol server lets AI coding agents such as Claude Code, Codex, and OpenCode read, search, and edit the vault directly.

• Block-Based Editor

  Rich editing mode with slash commands, wikilinks, and drag-and-drop media, alongside a raw Markdown mode for exact file control.

• Lightweight Native Performance

  Built on Tauri with a Rust core instead of a bundled Chromium runtime, giving fast startup and low memory usage compared to Electron-based apps.

• Cross-Platform Availability

  Desktop builds for macOS, Windows, and Linux, installable via direct download or Homebrew cask, with no account required.

Use Cases

• AI-Augmented Research : Researchers and writers can let Claude Code query years of accumulated notes to summarize topics or surface linked references.
• Personal Knowledge Management : Individuals organizing thousands of notes benefit from native relationships, wikilinks, and a type system for navigation.
• Version-Controlled Note-Taking : Teams or individuals who want auditable history and sync can rely on Git tracking every change to their vault automatically.
• Agent-Assisted Content Drafting : Writers can direct an AI agent to draft new pieces based on linked notes already stored in the vault.
• Migrating from Proprietary Tools : Users leaving cloud-locked apps like Notion can move to a local, file-based system without losing data portability.
