GOOD TO KNOW
Safety and privacy
Rewrites can change meaning
Quality and available rules vary by language; do not assume an English-level review everywhere.
Protect private material
Browser-add-on text is usually not stored, but Editor documents and AI Chat follow separate storage and processing rules.
Keep human control
Accept only changes you understand and can defend as your own writing.
