Writer Studio
Say what you mean. Better
Writer Studio is a native Mac app that rewrites, polishes, and translates your writing — emails, reports, essays, posts, anything — using AI that you control.
Paste your text, pick how you want it to sound, and get a better version in seconds.
No subscription required to get started, no account, no data collection.
YOUR CHOICE OF AI, INCLUDING FREE AND FULLY PRIVATE.
Writer Studio doesn't lock you into one AI provider. Choose whichever fits how you work:
Local (Ollama) — completely free, forever. Runs entirely on your own Mac. No internet connection required, nothing ever leaves your computer. Perfect for sensitive documents or if you'd simply rather not send your writing anywhere.
Apple Intelligence — Apple's own on-device AI, built into modern macOS. Free, private, and requires no setup at all.
OpenAI, Anthropic, and Google Gemini — for when you want the extra power of the latest cloud models. Bring your own API key; Writer Studio never sees it or charges you anything on top.
Switch between them anytime, right from the sidebar.
EIGHT WAYS TO REWRITE:
Proofread — fix spelling, grammar, and punctuation only, nothing else changed.
Improve — sharpen unclear or clunky writing.
Simplify — plainer language, easier to read.
Expand — add helpful detail and depth.
Shorten — trim it down to the essentials.
Professional — a polished business tone.
Academic — formal and structured.
Creative — vivid, engaging language.
Combine any mode with five reading levels (from Child to Professional) and six tones (from Warm to Persuasive), so the result sounds exactly the way you need it to, for exactly who's reading it.
TRANSLATE WHILE YOU REWRITE:
Writing in Spanish but need it in polished English? Writer Studio translates into 14 languages as part of the rewrite itself — not just word-for-word conversion, but genuinely well-written text in the target language, with your chosen tone and style applied.
SAVE YOUR OWN RECIPES:
Build Custom Presets for the rewrites you do again and again — a specific mode, tone, reading level, language, and even your own custom instructions, all saved under one name and applied with a single click. With a paid Apple Developer account, your presets even sync automatically across your Macs via iCloud.
SEE WHAT CHANGED, AND WHY IT'S BETTER:
Every rewrite comes with a clear list of what changed, plus an optional Style Analysis: a full scorecard covering readability, sentence variety, and paragraph flow, along with specific strengths, weaknesses, and suggestions. Don't need the deep-dive every time? Turn it off in one tap for a noticeably faster response.
WORKS THE WAY YOU DO:
Rewrite an entire document, or just highlight one sentence and fix only that — the rest of your text stays untouched.
Dictate instead of typing, using your Mac's built-in speech recognition.
Stop a rewrite mid-way if you change your mind, instantly.
Full Rewrite History, automatically saved, so you can go back and restore any previous version.
Print, email, or export your finished draft as an editable text file — right from the toolbar.
Assign a global keyboard shortcut to rewrite clipboard text from inside any app on your Mac, not just Writer Studio.
BUILT FOR THE MAC, NOT PORTED TO IT
Writer Studio looks and feels like it belongs on your Mac — a proper native sidebar, full keyboard shortcut support, VoiceOver accessibility, and a genuine Settings window. No web wrapper, no clunky cross-platform compromise.
YOUR WRITING STAYS YOURS:
Writer Studio has no servers of its own, no analytics, no tracking, and no accounts. Using the Local or Apple Intelligence engine, your text never leaves your Mac. Choose a cloud engine, and your text goes directly from your Mac to that provider, using your own key — never through us.
That's not a policy promise; it's simply how the app is built.
