AI Agent Sidebar for Obsidian

An Obsidian plugin that adds a sidebar where you can chat with AI agents (Claude Code, OpenAI Codex, Google Gemini, GitHub Copilot, and any OpenAI-compatible endpoint) and have them read, create, edit, rename, and delete files in your vault. Agents can be used via their CLI tools or directly through their APIs.

TL;DR

1. Get access to at least one agent — either install a CLI tool or grab an API key:

   • Claude Code CLI or Anthropic API key → see API Keys
   • OpenAI Codex CLI or OpenAI API key → see API Keys
   • Google Claude API key (API only) → see API Keys
   • GitHub Copilot CLI (CLI only)
   • A local Ollama, vLLM, or LM Studio server

2. Install the plugin:

   • Download main.js, manifest.json, and styles.css from the latest release
   • Copy all three files into <your-vault>/.obsidian/plugins/obsidian-ai-agent-sidebar/
   • In Obsidian: Settings → Community Plugins → enable "AI Agent Sidebar"

3. Open the sidebar from the ribbon icon or Ctrl/Cmd+P → "Open AI Agent Sidebar" and start chatting.
