AI Detector Free lets you paste text and instantly review AI-writing signals such as repetition, sentence variation, generic phrasing, vocabulary diversity, and predictability. The checker is designed to flag patterns that may appear in writing produced by ChatGPT, GPT-5, Claude, Gemini, and other generative AI systems. No signup or file upload is required.
Paste a complete passage into the box above and select Analyze text. The tool returns an AI signal score along with word count, sentence count, and average sentence length. Longer passages generally provide more writing-pattern information than very short samples.
Use the score as a screening signal rather than a verdict. AI-generated text can be edited by a person, and human writing can sometimes contain the same predictable or repetitive patterns that detectors associate with AI. For important decisions, compare the result with the writer’s drafts, sources, revision history, citations, and ability to explain the work.
This preview runs directly in your browser interface and is intended for quick text review. It is useful for students, teachers, editors, writers, publishers, website owners, and anyone who wants a second look at whether text contains AI-like writing patterns.
A free AI detector reviews text for writing patterns commonly associated with AI-generated content. It provides a signal, not proof of authorship.
It can flag general AI-like patterns that may appear in text from those systems, but it cannot identify a specific model with certainty.
Yes. The on-page preview is free to use and does not require an account or file upload.
Accuracy varies with text length, editing, writing style, and subject matter. Treat the score as a review signal rather than final proof.
