Writer Studio rewrites, proofreads, and translates your writing — using whichever AI you pick: free on-device Apple Intelligence, Google Gemini's free tier, or your own OpenAI/Anthropic account.
Choose from 8 rewrite modes, 5 reading levels, and 6 tones, translate into 14 languages, and see exactly what changed with a plain-English breakdown and optional style scorecard.
One-time purchase, no subscription. Available on Mac and iPad (as Writer Studio Pro). ALWAYS private, nothing collected, ever!
