+# 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.
