Say the same thing, land it better. ToneFix rewrites your texts, emails, and Slack messages in seconds, on your iPhone, without changing a single fact. Free to download. Nothing you write ever leaves your device. No account. No cloud. No subscription. WHAT IT DOES Paste a draft or use the keyboard and share sheet anywhere you type. Pick a tone, pick a channel, and ToneFix rewrites it while keeping your names, numbers, and dates intact. NINE TONES FOR REAL CONVERSATIONS โ€ข Less Rude โ€” soften sharpness and passive aggression โ€ข More Confident โ€” drop hedging words, sound decisive โ€ข Friendlier โ€” add warmth without losing your point โ€ข Shorter โ€” cut filler, keep every fact โ€ข Clearer โ€” make the ask unmistakable โ€ข More Executive โ€” crisp, composed, leadership-ready โ€ข More Human โ€” remove robotic, AI-sounding phrasing โ€ข Remove Fluff โ€” no jargon, just the message โ€ข Slept Last Night โ€” calm down a rambling, heated draft NEW WAYS TO GET IT EXACTLY RIGHT โ€ข Streaming rewrites โ€” watch each version appear in real time โ€ข Tone Intensity โ€” Subtle, Balanced, or Strong for every tone โ€ข What Changed โ€” a word-level diff shows exactly what moved โ€ข Refine โ€” ask for "shorter still," "warmer," or "more direct" with one tap, and undo anytime โ€ข Fact-Preservation Check โ€” a warning if a name, number, or date went missing โ€ข Reply Context โ€” paste what you're replying to for a rewrite that actually fits LEARN MY VOICE (Pro) Give ToneFix three samples of how you actually write, and it builds a custom tone that sounds like you, not like a template. PRESETS AND CUSTOM TONES Stack your favorite tone, intensity, and channel into one tap. Build your own tones for the exact situations you deal with โ€” the tough client, the group chat, the weekly update. WORKS WHERE YOU ALREADY TYPE โ€ข Keyboard โ€” presets, whole-message rewrite, live streaming preview, swap back, and your recent rewrites, all without leaving the keyboard โ€ข Share Sheet โ€” rewrite text from any app, or rewrite the text inside a screenshot with built-in image OCR โ€ข Shortcuts โ€” a "Rewrite Text" action with tone and channel parameters, plus "Rewrite Clipboard," for your own automations YOUR HISTORY, ORGANIZED Every rewrite is saved automatically. Tag it, search it with Spotlight right from your home screen, reuse it, or export your history to CSV. TONEFIX PRO Free gets you everything above, with 2 of your own presets plus every built-in preset. ToneFix Pro is a one-time $4.99 purchase, no subscription, and unlocks: โ€ข Custom tones and Learn My Voice โ€ข Unlimited presets โ€ข iCloud sync across your devices PRIVACY AND REQUIREMENTS ToneFix runs on Apple's on-device Foundation Models โ€” your text is processed on your iPhone and never sent to a server. AI-powered rewrites require Apple Intelligence (iPhone 15 Pro or later, and all iPhone 16 and iPhone 17 models). On other iOS 26 devices, ToneFix still works with a built-in rule-based rewriter that handles Shorter, Clearer, Remove Fluff, and More Confident, and cleans up the rest. Built for iOS 26 with an accessible, native design: full VoiceOver support, Dynamic Type, and Reduce Motion respected throughout. No account. No ads. No data collection. Just better messages, sent from wherever you already are.
