About Claudian

Claudian is an open-source Obsidian community plugin that embeds AI coding agents — Claude Code, Codex, and Opencode — directly into your vault.

The Mission

We believe that your knowledge base and your development environment should be the same place. Obsidian's local-first, markdown-native vault is the perfect foundation for an AI-powered developer workspace.

Claudian bridges the gap between note-taking and AI-assisted coding — turning every vault into a fully capable development environment where the AI has deep context about your work, your project, and your thinking.

Open Source

Claudian is MIT-licensed and developed in the open. Contributions, bug reports, and feature requests are welcome on GitHub.
