AI proofreading that fixes errors without changing your voice
ToneMate proofreads your writing with AI directly in macOS — fixing grammar, spelling, punctuation, and style inconsistencies in seconds. Unlike Grammarly, which works only in supported apps via a browser extension, ToneMate works system-wide in any macOS application: Mail, Notion, Slack, Pages, Word, your browser, or any text field. No copy-pasting required.
The AI understands context, so it corrects errors without changing your meaning or voice. It fixes awkward sentence structure, ensures verb tense consistency, catches repeated words, and aligns your phrasing with the right level of formality — all while preserving the intent of what you wrote. Ideal for client proposals, support responses, product docs, and any message where credibility matters.
After proofreading, chain it with Rewrite if you also want a tone change, or with Translate to produce a clean version in another language. Everything runs with one keyboard shortcut, one payment, no subscription.

Everything you need to know about AI proofreading on Mac
How is ToneMate different from Grammarly?
Grammarly works only in supported apps (mainly browsers and a few integrations) and requires a monthly subscription. ToneMate works in any macOS application via a global keyboard shortcut — including native apps like Mail, Pages, and Notion where Grammarly doesn't reach. ToneMate is also a one-time purchase with no recurring fees, and you can use local AI models to keep your text private.
Will it change the meaning of my text?
No. The AI focuses on correcting errors and improving clarity while preserving your intent, voice, and structure. It won't rewrite what you wrote into something different — if you want tone or style changes, use Rewrite instead, which is optimized for that purpose.
What does AI proofreading actually fix?
ToneMate checks and corrects: grammar errors, spelling mistakes, punctuation issues, verb tense consistency, awkward phrasing, redundant words, and sentence clarity. It also adjusts for formality level and style consistency across long documents.
Can I use it for languages other than English?
Yes. ToneMate's proofreading works in English, Spanish, French, German, Portuguese, and many other languages. The AI understands language-specific grammar rules for each, so corrections are contextually accurate per language.
Does it work in long documents or only short texts?
ToneMate handles both short messages and long documents. For very long texts, you may want to proofread in sections to ensure the best accuracy. It works consistently across proposals, reports, documentation, and email threads.
Can my text be processed privately without sending it to the cloud?
Yes. ToneMate can use local AI models via Ollama or MLX to proofread your text entirely on your Mac, without sending it to any external server. This is ideal for sensitive documents, legal content, or anything you want to keep confidential.
Write cleaner. Ship faster. Stay credible.
ToneMate is the AI proofreading tool for macOS that works in any app, fixes errors without changing your voice, and requires no subscription.
