An AI Coding Experience Built for Knowledge Workers

More than a chat interface — Claudian gives AI deep access to understand and operate your Obsidian vault

  • Inline Edit

    Select text or place your cursor, then hit the hotkey to edit directly in your notes. Word-level diff preview gives you precise control over every change.

  • Slash Commands & Skills

    Type / or $ to invoke reusable prompt templates and skills from vault-level or user-level scopes. Extend your workflow with custom commands.

  • @Mention Anything

    Type @ to reference vault files, sub-agents, MCP servers, or files in external directories. The AI gets full context instantly.

  • Plan Mode

    Toggle with Shift+Tab. The AI explores and designs before implementing, presenting a plan for your approval — no blind execution.

  • Instruction Mode

    Use # to add refined custom instructions from the chat input. Adjust AI behavior in real time without leaving the conversation.

  • MCP Servers

    Connect external tools via the Model Context Protocol — stdio, SSE, and HTTP transports supported. Claude includes in-app MCP management.

  • Multi-Tab Conversations

    Run multiple independent chat tabs simultaneously with full conversation history, fork, resume, and context compaction.

  • Multi-Provider Support

    Switch between Claude Code, Codex, and Opencode in a unified interface, all sharing the same conversation model and workflow.

Frequently Asked Questions

I see "spawn claude ENOENT" or "Claude CLI not found". How do I fix it?
The plugin can't auto-detect your Claude CLI installation. This is common with Node version managers (nvm, fnm, volta). Fix: leave the CLI path setting empty so Claudian can auto-detect. If that fails, run which claude (macOS/Linux) or where.exe claude (Windows) and paste the path into Settings → Advanced → Claude CLI path.
The npm CLI and Node.js aren't in the same directory — what do I do?
Run dirname $(which claude) and dirname $(which node) to check if they match. If not, install the native binary instead, or add the Node.js path to Settings → Environment: PATH=/path/to/node/bin.
What features does Codex support?
Codex supports: send, streaming, cancel, history reload, fork, plan mode, image attachments, inline edit, and $ skills. Not yet supported: rewind, runtime-discovered provider commands, in-app MCP management, and Claude plugin integration.
Which Claude CLI path should I use on Windows?
For native installs use claude.exe; for npm installs, run npm root -g to find the global root and use cli-wrapper.cjs from there. Avoid .cmd and .ps1 wrappers, and the legacy cli.js.
Does Claudian collect any of my data?
No telemetry whatsoever. What gets sent to the API: your input, attached files, images, and tool-call outputs — to the API provider you configure (Anthropic or OpenAI by default). Local storage: vault/.claudian/ (settings) and vault/.claude/ (Claude provider files).
Which platforms are supported?
Claudian is desktop-only (macOS, Linux, Windows), requiring Obsidian v1.4.5+. Mobile (iOS/Android) is not supported.
