Tolaria

Tolaria is an open-source web app and server that manages markdown knowledge bases. It functions as a desktop application for macOS, Windows, and Linux, allowing users to operate personal second brains, organize company documentation for AI context, or store procedural memory for AI assistants. The software is designed for users who require a local environment to manage large volumes of notes without relying on cloud services.

The software follows a files-first approach where notes are stored as plain markdown files with YAML frontmatter. Each vault is treated as a git repository, enabling full version history and the use of any git remote without requiring a central account or subscription. The application operates entirely offline to prevent vendor lock-in, ensuring that all data remains under the direct control of the user and is accessible through any standard text editor.

Key features

• Plain markdown file storage for data portability
• Git integration for version control and synchronization
• Offline-first operation with no account requirements
• Keyboard-centric design with a dedicated command palette
• Support for AI agent integration via an AGENTS file
• Setup paths for Claude Code, Codex CLI, and Gemini CLI
• Use of types as navigation lenses rather than strict schemas
• Cross-platform availability for Windows, macOS, and Linux

Tolaria is built using Tauri, React, and TypeScript. It is designed for power users who prefer keyboard navigation and a non-proprietary data format. The architecture ensures that the vault of files works well with AI agents, while remaining functional for those who prefer manual note-taking. Because it relies on standard markdown and git, the data remains accessible through any text editor or version control tool independently of the application, removing the need for export steps when switching tools.

This tool is a local-first knowledge management system for users who prioritize data ownership, privacy, and AI compatibility.
