A right-side panel (alongside Chat / Outline / Checks / Share) that helps people writing in a non-native language rewrite and understand their text.
Panel actions —selection-driven, with a fallback scope (word / sentence / paragraph / document):
- Make it natural
- Fix grammar & spelling
- Make it simpler
- Rephrase (2–3 alternatives)
- Tone: Neutral, Formal, Casual, Friendly, Confident, Professional, Warm, Concise, Academic
- My voice — match how the user usually writes (built later from writing samples; ships as a "Set up" state first)
Rewrites return 2–3 candidates; the user previews and picks one to apply.
Hover popover on a word shows: formal definition, what it means in this context, tappable synonyms, and 2–3 full-sentence rewrites with Apply.
