# Claudian (YishenTu/claudian)
|
|
|
|
**Type**: Native Obsidian plugin (TypeScript, embedded Claude Code/Codex)
|
|
**URL**: https://github.com/YishenTu/claudian
|
|
**Install**: BRAT or manual (not yet in community store)
|
|
|
|
## What It Does
|
|
|
|
Embeds Claude Code (or Codex CLI) directly inside Obsidian as a sidebar chat. The vault becomes the agent's working directory — all Claude Code tools work natively inside Obsidian.
|
|
|
|
## Key Features
|
|
|
|
### Inline Edit with Word-Level Diff
|
|
Select text in a note + hotkey → Claude proposes edit with word-level diff preview → one-click apply. Best-in-class inline editing in the Obsidian AI ecosystem.
|
|
|
|
### Plan Mode (Shift+Tab)
|
|
Agent explores and designs before implementing. Presents a plan for approval before any file changes. Mirrors Claude Code's own plan mode.
|
|
|
|
### @mention System
|
|
Type `@` to reference:
|
|
- Vault files
|
|
- Sub-agents
|
|
- MCP servers
|
|
- Files in external directories (outside vault)
|
|
|
|
### Instruction Mode (#)
|
|
Add refined custom instructions directly from chat input — persisted for the session.
|
|
|
|
### MCP Server Integration
|
|
Connect external tools via stdio, SSE, or HTTP. Claude manages vault MCP in-app; Codex uses CLI-managed config.
|
|
|
|
### Multi-Tab Conversations
|
|
Multiple chat tabs, conversation history, fork, resume, compact mode.
|
|
|
|
## Privacy
|
|
- No telemetry
|
|
- Settings stored in `vault/.claudian/`
|
|
- Claude files in `vault/.claude/`
|
|
- Transcripts in `~/.claude/projects/`
|
|
|
|
## Relevance to claude-obsidian
|
|
Claudian is a native plugin (different category) but its Plan Mode, @mention, and inline edit patterns could inspire new features in claude-obsidian skills — particularly for the canvas and wiki-query workflows.
