Humanize Studio rewrites AI-generated text so it reads naturally — and checks any text with a built-in AI detector, so you always know your score before you share. Private by design: your text is never stored on our servers. Most "humanizer" apps are a thin wrapper around a single model. Humanize Studio runs a 3-round rewrite — each pass takes a different approach and re-checks the result — then shows you a real detector score, not a vague promise. WHY HUMANIZE STUDIO • Reads naturally — turns stiff, robotic AI drafts into clear writing in your tone. • Detector built in — check any text and see a Human/AI score before you share. No guessing. • Private by design — your text is never stored on our servers. We keep only an anonymous metric, never your words. • Honest free tier — real free use every day, no bait-and-switch. • Fast & native — built for iPhone. Paste, scan with the camera, or upload in one tap. • Facts kept — figures, quotes, and proper nouns are preserved, and we warn you if anything drifts. HOW IT WORKS 1. Paste, type, scan, or upload your text. 2. Pick a tone and strength. 3. Get natural, human-sounding writing — plus an AI-detector score. WHO IT'S FOR Writers, students, professionals, marketers, and non-native English speakers who want AI drafts to read like a person wrote them — and want to check before they share. FREE & PRO Free every day, up to 500 characters per rewrite. Pro unlocks up to 50,000 characters, unlimited daily use, and the full detector. • Pro Weekly — $6.99/week, with a 3-day free trial • Pro Yearly — $59.99/year (best value) Subscriptions are billed to your Apple ID.
