claudian

Claudian is an Obsidian plugin that turns your vault into an AI agent's working directory. It supports multiple coding agent harnesses including Claude Code, Codex, Grok Build, OpenCode, and Pi, allowing the agent to read, write, edit, and search files directly in your vault. Key features include: - Inline Edit: Select text and use a hotkey to edit notes directly with word-level diff preview. - Slash Commands & Skills: Type / or $ for reusable prompt templates from user- and vault-level scopes. - @mention: Reference vault files, folders, and Collab member changes; use # to reference Collab tickets. - Instruction Mode: Add refined custom instructions from chat input. - MCP Servers: Connect external tools through each agent's native CLI-managed MCP configuration. - Tabs & Session Management: Multiple tabs in single-panel mode or a persistent session manager in dual-pane mode. - Collab Mode (Experimental): Collaborate on shared projects with other Claudian users via local network Git synchronization. Requirements include at least one supported agent CLI, a compatible subscription or API provider (e.g., OpenRouter, Kimi, GLM, DeepSeek), Obsidian v1.13.0+, and desktop OS (macOS, Linux, Windows). Collab Mode additionally requires Git. The plugin supports 10 locales for internationalization. Privacy-wise, Claudian sends input, attached files, and tool call outputs to the selected API provider but runs no telemetry. Collab Mode traffic stays on the local network between invited teammates. The architecture is provider-neutral, with separate adaptors for each supported agent (Claude SDK, Codex JSON-RPC, Grok ACP, OpenCode, Pi RPC) built on a shared core runtime. The project does not accept pull requests that add new providers to maintain product-quality boundaries.
