What it does
Nine tones, and a check that keeps your facts
Paste a draft, or use the keyboard and share sheet anywhere you already type.
- 01
Nine tones for real conversations
Less Rude, More Confident, Friendlier, Shorter, Clearer, More Executive, More Human, Remove Fluff — and Slept Last Night, for the draft you wrote angry.
- 02
Every fact stays put
The fact-preservation check warns you if a name, a number or a date went missing somewhere in the rewrite.
- 03
What changed, word by word
A word-level diff shows exactly what moved. Refine asks for “shorter still,” “warmer” or “more direct” in one tap, and undoes it just as fast.
- 04
Tone intensity
Subtle, Balanced or Strong for any tone, streaming in as it writes so you can stop when it is already right.
- 05
Works where you already type
A keyboard with presets and a live preview, a share sheet that can read text straight out of a screenshot, and Shortcuts actions for your own automations.
- 06
Learn My Voice
Give ToneFix three samples of how you actually write and it builds a custom tone that sounds like you, not like a template.
On-device intelligence
ToneFix runs on Apple’s on-device Foundation Models — your text is processed on your iPhone and never sent to a server. AI rewrites need Apple Intelligence (iPhone 15 Pro or later, and every iPhone 16 and 17). On other iOS 26 devices a built-in rule-based rewriter still handles Shorter, Clearer, Remove Fluff and More Confident.
Free, with one upgrade
Free gets you every tone, every built-in preset and two of your own. ToneFix Pro is a one-time purchase — no subscription — and adds custom tones, Learn My Voice, unlimited presets, and iCloud sync across your devices.
Private by design
No account, no ads, no analytics, no servers of ours. The keyboard needs Full Access to read and replace the text you are rewriting, and it logs nothing: no keystrokes are stored and nothing is transmitted.
