ReWriteMe is a focused AI writing assistant for turning rough drafts into clear messages, emails, notes, captions, and replies. Type, paste, or dictate a draft, then choose the tone that fits: friendly, professional, concise, formal, casual, or supportive. ReWriteMe rewrites your text in the original language, the system language, or another supported language, so you can polish and translate in one flow. Use ReWriteMe to: - Rewrite emails and messages before sending - Fix grammar and make wording clearer - Make replies warmer, shorter, or more professional - Dictate an idea and clean it up - Polish captions, notes, and everyday text - Regenerate, copy, or replace the result quickly ReWriteMe uses on-device writing models when available, including Apple Intelligence and a local MLX fallback on supported devices. It is built for quick edits, not long documents: open the composer, paste the draft, pick a tone, and send a cleaner version.
