GPT Detector
GPT models power many writing apps, chatbots and browser extensions. This detector estimates whether a passage carries typical GPT-style patterns.

GPT text in everyday tools
Email assistants, grammar tools and chat apps often use GPT models behind the scenes. Lightly AI-polished human text may show partial AI signals — which is why results include a “mixed” category.
What a GPT detector looks for
GPT-style text tends to be fluent, evenly paced and cautious. Typical signs include stock transitions (“Moreover,” “Additionally,” “In conclusion”), hedged statements, lists of three, generic examples and few concrete names, numbers or personal details. The detector weighs these signals across the whole passage and sentence by sentence.
Partial AI assistance
Much real-world writing is neither fully human nor fully AI: a person drafts, then an assistant polishes grammar; or an AI drafts, then a person rewrites. These texts often produce “mixed” results with medium or low confidence, and the sentence highlights show which passages carry the strongest AI signal.
Getting more reliable results
Use longer samples, check the original rather than a translated or reformatted copy, and avoid checking lists, tables or code, which have little natural variation. Treat the result as a starting point and look for supporting evidence.
Understanding the limits
No AI detector is 100% accurate. Results are probabilistic estimates and should never be used as the only evidence that someone used AI. Treat them as one signal alongside drafts, revision history, and a conversation with the writer.
Frequently asked questions
Is a GPT detector the same as an AI detector?
Practically yes. Our engine looks for patterns common to large language models in general.
What is the minimum text length?
80 words. Around 300 words or more gives the steadiest results.
Does it work on code?
No. The detector is designed for natural-language prose, not source code.
Is my text stored?
No. It is analyzed in your browser and never uploaded.
