Tonespin: Rewrite Message Tone

Rewrite any message in the right tone, on your iPhone or iPad. One purchase, no subscription, no account, no word limits. Paste or share text, pick a tone, and get a rewrite you can copy or send. On devices with Apple Intelligence (iOS 26 or later, turned on in Settings), Tonespin uses Apple's on-device language model. On every other device it uses its own deterministic rule engine. Either way your text is rewritten on the device; Tonespin has no server and no account. REWRITE - Six tones: Formal, Casual, Professional, Playful, Concise, Friendly. - Custom tone profiles: start from a tone and choose contractions, filler removal, emoji and punctuation. - Length control from much shorter to much longer, and formats for bullets, numbered steps, email or a short message. - Try again for a different wording, then swap single words in Word Studio. NEW IN 4.0 - Share extension: select text in Mail, Notes, Messages or Safari, tap Share, choose Tonespin, pick a tone and copy the result. - Shortcuts and Siri: "Rewrite Text" and "Rewrite with Preset" actions return the rewritten text to your shortcut. - Saved presets: keep your favorite tone, length and format together and apply them with one tap. - Fact check on every rewrite: numbers, times, prices, links, email addresses and @handles from your original are checked, and anything that changed or went missing is flagged before you send. - Searchable history: every rewrite is kept on the device (you can turn this off), with favorites, "rewrite again" and plain-text export. MESSAGE PACKS Build Professional, Friendly and Concise versions of one message side by side, add exact phrases that must stay, and save or export the comparison. CHECK YOUR WRITING Readability scores, clarity flags (passive voice, hedging, long sentences), text statistics and platform-fit meters for posts and texts. WHAT TO KNOW - The rule engine changes words, contractions, filler and punctuation. It does not restructure sentences the way a language model does. Apple Intelligence rewrites need a supported device with Apple Intelligence turned on. - Tonespin checks exact strings, not facts or meaning. Read every rewrite before you send it. - Nothing is sent automatically. Sharing exports only the text you choose. - The share extension does not save history; open the app for history and presets. iPhone and iPad.
