Choose and configure the AI provider that fits your workflow

Claude Code Setup

Claude Code is the default and primary provider for Claudian, with full feature support.

  1. Install Claude Code CLI: visit code.claude.com to download and install
  2. Authenticate your Claude account: run the claude command and follow the prompts
  3. Open Claudian settings (Obsidian Settings → Claudian) — the CLI path is usually auto-detected
  4. If auto-detection fails, run which claude (macOS/Linux) or where.exe claude (Windows) and set the path manually
Tips:
  • Compatible third-party providers like Openrouter and Kimi are supported
  • Configure the model (claude-opus-4, claude-sonnet-4, etc.) via the Claude Code CLI
