Undetectable Text: AI Detector

Undetectable Text: AI Detector is an AI humanizer and AI detector in one app. Check any writing or image for AI-generated content, see exactly which sentences get flagged, and rewrite them so your text reads natural, human and undetectable by AI checkers.
AI DETECTOR
Paste your text or upload a PDF or DOC file and tap Check. You get a clear AI percentage score with paragraph-level highlighting, so you know which lines look AI written and which read like a human wrote them. Works with essays, assignments, blog posts, emails, product descriptions and more.

AI HUMANIZER
If your text gets flagged, switch to the Humanize tab. The AI humanizer rewrites the same content while keeping your original meaning intact. The result is natural, human-sounding writing that stays undetectable to most AI detection tools. Not happy with the first version? Humanize again and get a completely new rewrite every time.

CHECK, HUMANIZE, RE-CHECK
Go back and forth between the detector and the humanizer until your writing passes. Turn a 90% AI score into a 90% human score in a few taps.

HUMANIZE IN 6 LANGUAGES
Rewrite content in English, French, German, Dutch, Spanish and Turkish. Pick your content language and the humanizer adapts to it.

AI IMAGE DETECTOR
Not sure if a photo or artwork is real? Upload any image and the AI image detector analyzes it and tells you how likely it is to be AI generated, with a confidence score. Check images before you share, publish or trust them.

WHO IT IS FOR
- Students checking assignments and essays before submission
- Writers, bloggers and marketers reviewing drafts
- Freelancers making sure client work reads naturally
- Anyone who wants a second opinion on whether text or an image came from an AI tool

FREE AND PRO
The free plan gives you a daily word limit and a set number of checks per day, shared between the AI detector and the AI humanizer. Upgrade to Pro for a higher word limit, unlimited daily checks and direct PDF and DOC uploads.

HISTORY ON YOUR DEVICE
Everything you check or rewrite is saved locally on your phone, split into separate Detect and Humanize sections, so you can look back any time.

PRIVACY
Your text and images are sent to our detection and rewriting servers only to generate a result. They are not stored afterward or used for anything else. There are no ads in this app.

Make AI-assisted writing sound human, bypass AI detection and keep your content undetectable with one simple AI humanizer app.
