Grammate is best for selected passages: emails, messages, notes, document paragraphs, form fields, and other everyday writing that needs a quick review.
Can I use Grammate with Windows apps in local mode?
Yes. Local mode is available when your local AI provider is configured, which is useful when you want a privacy-focused correction workflow on your own PC.
