## Obsidian Chat: an agentic AI assistant that lives in your vault

I wanted a chat assistant inside Obsidian that could actually do things. Not just answer questions, but read my notes, make edits, create files, update frontmatter, and navigate my vault.

I couldn’t find one that was simple enough. Claude Code Sidebar is amazing and I use it daily but it only works on Desktop.

Most AI plugins for Obsidian require a pile of configuration, break on mobile, or can’t actually touch your notes. So I built Obsidian Chat.

### What it does

Pick Anthropic or OpenAI, enter your API key, and start talking. The AI has 14 tools that map directly to Obsidian’s Vault API:

- Read, edit, create, rename, move, and delete notes
- Search your vault by filename or content
- Read and update YAML frontmatter
- Find backlinks
- Open files in the editor
- Ask you clarifying questions when needed

It reads before it edits. It makes surgical changes, not full rewrites. It acts when you say “do it” without asking again.

### Selection scope

Select text in a note, right-click, “Send selection to Chat”. A pill shows your selection above the input. The AI works only within that text, leaving everything else alone.

### Works everywhere

Mobile is a first-class citizen. The sidebar works on iOS, Android, and desktop. Conversations persist across restarts, stored locally, never synced. API keys live in your OS keychain, never in data.json.

### Install via BRAT

1. Install BRAT from Community Plugins
2. Add Beta plugin with repo: omarshahine/obsidian-chat
3. Enable the plugin
