Undetectable AI is a two-sided platform: an AI detector that checks whether text, images, voice, or video were AI-generated, and an AI Humanizer that rewrites AI-generated text so it reads naturally and passes major AI detectors, with a money-back guarantee if flagged output isn't made human. It also includes a paraphrasing tool, AI essay writer, plagiarism checker, and watermark remover.

FAQ
Is Undetectable AI free to use?
There's a free trial limited to 250 words; additional usage requires a paid plan starting at $5/mo (billed annually).
What happens if my humanized text still gets flagged as AI?
Undetectable AI offers a money-back guarantee if output it humanized is flagged as AI-generated.
Does Undetectable AI only humanize text, or can it detect AI content too?
Both — it includes an AI Detector for text, images, voice, and video, alongside its AI Humanizer and related writing tools.
Where it holds up
- Money-back guarantee if humanized output is still flagged as AI-generated
- Combines both AI detection and AI humanizing in one platform, across text, image, voice, and video
- Writing level matching helps output read naturally for the intended audience
- API access for integrating detection or humanizing into other workflows
- Large, established user base (24M+ users) with Forbes recognition
Where it falls short
- Free trial is limited to just 250 words before requiring a paid plan
- Using AI humanizers to pass detection checks can violate academic, platform, or publisher policies depending on context
- Monthly word limits are capped per plan, and heavier usage requires upgrading
