Undetectable AI is a browser-based tool for checking AI-generated text and rewriting it to read more like natural human writing.
AI text detection
Paste any text to see how likely it is to be flagged as AI-written. The service evaluates content using signals similar to popular AI detectors and returns an estimated risk score.
- Check text created with ChatGPT, Gemini, Claude, Llama, and other models
- Get a quick assessment of whether your content may be labeled as AI-generated
Humanize rewriting
In addition to detection, Undetectable AI includes a Humanize feature that rewrites text to sound more natural and varied while improving readability.
- Useful for essays, articles, marketing copy, emails, and other written materials
- Helps reduce the chance of triggering AI detectors while keeping the message intact
Who it’s for
Undetectable AI can fit students, copywriters, and marketers—anyone who needs text that reads naturally and may be reviewed by AI-detection tools. It runs directly in the browser and works with a simple paste-and-check workflow.
