Description

Undetectable AI is an AI detector that lets users paste text or upload a file to check whether content is likely to be flagged as AI-generated. It supports detection for text from ChatGPT, GPT-5, Gemini, Claude, Llama, and paraphrased content, and it also includes an AI Humanizer and AI Image Detector.

The page emphasizes instant results, multi-detector comparisons, and support for free checking, along with a Chrome extension, word counter, sentence rewriter, and API access.
