Mo on the subscription you already pay for.

Install Claude Code or Codex CLI if you have not. Open a terminal and sign in once: start claude and log in, or run codex login. That is the whole setup on the agent side.

Then open Settings → Integrations. Under Apps and Agents, click Connect on Claude or OpenAI Codex; the row shows when Morion can run on that subscription. If you signed in after opening the app, click Refresh to detect the login again.

On Windows and Linux, use the Claude Code login; the Codex route runs on macOS for now.

Open Settings → Smart Indexing → Indexing Models and pick Claude CLI or Codex CLI. Indexing and Ask Mo answers then run on that login.

Mo Assistant, the chat inside the app, is the one exception: it needs an OpenRouter key or a local Ollama, and it is part of Pro.

Open Folder Settings → AI Access and turn on AI access. Indexing follows the project setting; if the tab says indexing is off at the project level, turn it on in the project settings. The indexing banner shows progress.

Once the first pass is done, ask Mo something about the folder from Claude Code or Codex; the answer runs on the same login. Check that the answer cites your notes and carries a status on each claim.

Cost: nothing beyond the subscription you have. Indexing a large folder draws on the same limits as your agent sessions, Start with one folder.

Mo indexes and answers on the account you already pay for. Nothing else to sign up for, and no second bill. On Pro you can add an OpenRouter key or a local Ollama later if you want a specific model.
