What is Undetectable AI?
Undetectable AI is an AI content detection platform that analyzes text and images for signatures of generation by models such as ChatGPT, GPT‑4, GPT‑5, Gemini, Claude, Llama, and other large language models. It aggregates results from multiple detection engines and presents a combined probability score, allowing users to see how different tools rate the same content.
The system supports paraphrased and rewritten AI text, helping to identify content that has been obfuscated or re‑phrased by rewriting tools. An optional AI‑humanizer can adjust flagged text to reduce detection scores while preserving meaning. The service includes a Chrome extension for on‑the‑fly detection in web pages, an API for automated workflows, and a bulk‑scan feature for large documents.
Multilingual detection is available for over 50 languages, making the tool applicable to academic, editorial, marketing, and business settings. All user submissions are processed in memory and not stored, ensuring privacy for researchers, educators, and content creators.
