AI Detector & Text Rewriter for iPhone
Naturi is an iPhone app that checks how AI-written your text sounds and rewrites it so it reads more naturally. Paste an essay, email or post, see which sentences read like a chatbot wrote them, then humanize it at Light, Medium or Strong intensity. The AI check is free (3 per day); humanizing is part of Naturi Pro, which starts with a 3-day free trial. Review the result yourself: Naturi helps text sound natural, it does not guarantee how any detector will score it.

Frequently asked questions
What is Naturi?
Naturi is an iPhone app that works as an AI detector and an AI text humanizer in one. It scores how AI-like a text sounds, highlights the sentences that give it away and rewrites the text to read more naturally.
Is Naturi free?
Checking text for AI is free, up to 3 checks per day. Humanizing text needs Naturi Pro, which is $5.99 per week with a 3-day free trial, or $49.99 per year.
Does Naturi guarantee that Turnitin or GPTZero will not flag my text?
No, and no honest tool can. Detectors differ and change over time. Naturi rewrites text so it sounds more natural and shows its own before and after score, but you should read the result and judge it yourself.
Which languages does Naturi support?
The app and the writing support English, German, Spanish, French, Portuguese, Russian, Japanese, Korean and Chinese. Voice input works in 9 languages.
Can I use my voice instead of typing?
Yes. Tap the microphone, dictate your draft and Naturi puts the text in the editor, ready to check or humanize.
How long can the text be?
Up to 6,000 characters per request. For longer documents, split them into sections.
Can I import a file or a photo of a page?
Yes. You can open PDF, DOCX or TXT files or scan a page with the camera. Text recognition runs on your device.
What are Light, Medium and Strong?
They set how much Naturi changes. Light keeps your wording and smooths the robotic parts; Strong rewrites sentences more freely. You can also pick a tone and a writing mode.
