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.
