Paste AI text. Get clean, natural writing. Clean Paste strips the hidden characters, AI punctuation and formatting clutter that come along when you copy from ChatGPT, Claude, Gemini and other AI tools. Then it helps you rewrite what still sounds robotic, all on your device. ONE TAP, CLEAN TEXT • Removes invisible characters: zero-width spaces, hidden Unicode tags, soft hyphens and odd spacing • Swaps em dashes, curly quotes, bullets and ellipses for plain punctuation • Strips markdown leftovers like ##, bold, backticks and > quotes • Auto-clean works as you paste, and a clear summary shows every fix FIND WHAT SOUNDS LIKE AI The AI Tells scanner highlights the words and habits that give writing away: "delve", "tapestry", "it's important to note", "not just X, but Y", and heavy dash use. You get a score for the whole passage, and each tell can be fixed with one tap, with Fix All, or by having Apple Intelligence rewrite the sentence. REWORD WITH APPLE INTELLIGENCE Reduce Watermarking rewords text with synonyms or a full on-device rewrite, so the wording is genuinely yours. PROFILES AND YOUR OWN RULES • One-tap profiles for Email, Code, Social and Essay • Custom rules swap any word you never want to see, like "utilize" → "use" • Every option can be switched on or off to suit you CLEAN FROM ANYWHERE • Control Center and the Action Button • Siri: "Clean my clipboard with Clean Paste" • Shortcuts actions for your own automations • Share sheet: select text in any app and tap Clean Paste • On Mac, press ⌘⇧K in any app to clean your clipboard instantly SEE EXACTLY WHAT CHANGED A detailed change report lists every edit with its surrounding text. Export it as a PDF or CSV. PRIVATE BY DESIGN Everything runs on your device. Your text is never uploaded, and there's no account and no subscription: pay once and every feature is yours. Made for students, writers, marketers, developers and anyone who pastes AI text into email, essays, posts or code. Clean Paste cleans and rewords text. It can't guarantee how any AI detector will score your writing, and no tool can.
