> CoAuthor is the assistant that waits. Select a passage, ask, and review tracked suggestions before they land.

## Steps

1. **Open a chapter** — Work in the manuscript editor.
2. **Ask** — Select text or place the caret; ask for a sharper line or a continuation.
3. **Accept** — Approve suggestions — or reject and keep your words.

## Modes

Review waits on everything; Safe allows small line edits through; Autorun is for when you trust the run.

## FAQ

### Does CoAuthor need tokens?
