AI Text & Content Detector
Analyze essays, articles, and blog drafts for AI probability with sentence-by-sentence pattern detection, burstiness variance, and vocabulary predictability.
Frequently asked questions
How does the AI detector work?
It looks for patterns that are common in AI writing: how much sentence length varies (burstiness), how varied the vocabulary is, and which sentences read as very predictable. Then it gives an overall AI probability.
Is it 100% accurate?
No AI detector is. Treat the score as a hint, not proof. Short texts, heavily edited texts and writing by non-native English speakers can give wrong results, so don’t use the score alone to judge someone’s work.
What do the sentence colors mean?
Each sentence is marked as AI, Mixed or Human, so you can see which parts of the text look machine-written and which look natural.
How much text should I paste?
More text gives a more reliable result. A few paragraphs work much better than one or two sentences.
Is it free?
Yes. It’s free and you don’t need to sign up. The tool is still in beta, so results will keep improving.
