Claudian
Obsidian plugin that runs AI coding agents inside your notes vault
What it is
Claudian adds a chat panel to Obsidian that connects to coding agent CLIs such as Claude Code, Codex, OpenCode, Grok Build and Pi, using the vault as the agent's working directory. The agent can read, edit, search and run commands across your notes, with inline edits shown as word-level diffs, slash commands and skills, @mentions of files, multiple tabs and sessions, and MCP server connections. Obsidian users who already pay for a coding agent subscription can use it to work on their notes the way developers work on code.
