Tolaria is an open-source, local-first "second brain" designed for the AI era, focusing on data ownership and seamless integration with version control and artificial intelligence.

The main features of this tool include:

• Local-First Markdown Architecture: Every note is stored as a standard Markdown file with YAML frontmatter directly on your disk. There is no proprietary database, allowing you to read or grep your notes with any editor or terminal tool.

• Rich Block-Based Editor: The application features a sophisticated editor supporting slash commands, wikilinks with autocomplete, whiteboards, and media previews while ensuring all content remains durable in your vault files.

• Fully Integrated Git Client: Unlike tools that require external plugins for syncing, Tolaria has a built-in Git client that allows you to commit, push, and browse version history for individual notes or the entire vault.

• AI Agent & Model Support: It is built to work with the latest AI tools, supporting local agents (like Claude Code or Gemini) for tool-backed editing and direct API providers for chatting over your note context.

• Native Knowledge Relationships: It treats relationships as first-class citizens, utilizing wikilinks and structured properties to organize notes into a cohesive network of knowledge.

• Open Source & Free: Distributed under the AGPL-3.0 license, the tool requires no account and is "free forever," prioritizing user privacy and transparency.

• Expert-Driven Design: The tool was created by Luca (founder of Refactoring) based on his experience managing over 9,000 notes and publishing 300+ technical articles.
