Refine is a macOS app that provides AI powered grammar checking, fluency refinement, rewriting, translation, and text to speech entirely on device. Unlike cloud based tools like Grammarly, Refine processes all text locally using advanced AI models, ensuring that your writing never leaves your Mac. It works across a wide range of apps—including Mail, Messages, Safari, Chrome, Pages, Word, Slack, Notion, and many more—without requiring any setup. Simply start typing and get instant suggestions.
