Free AI Content Detector
Paste any text to check how likely it was written by AI. You get a clear probability score in seconds — free, no signup.
No detector is 100% accurate — treat this score as one signal, not proof.
How to use
- Paste the text you want to check into the box above. A paragraph or more gives the most reliable result — very short snippets are hard to judge.
- Click Analyze Text and wait a few seconds while the model scores it.
- Read the AI probability score, the verdict band, and the two bars showing how the result breaks down.
Frequently asked questions
How accurate is this AI content detector?
It makes a statistical guess based on writing patterns, and it works best on longer passages (150+ words). Short texts, heavily edited drafts, and formal writing can all throw it off — so use the score as one signal among others, never as final proof.
Does it detect text from ChatGPT, Claude, and Gemini?
It looks for common machine-writing patterns shared by most large language models, including the big three. Newer models keep getting better at sounding human, so detection gets harder with each generation.
Why did my own writing score as AI?
Detectors flag predictable, uniform writing — and humans write that way too, especially in formal or technical text. A false positive doesn’t mean you did anything wrong; it means the text reads smoothly and evenly.
Is my pasted text stored anywhere?
No. Your text is sent to the analysis model only to produce the score, and we don’t keep copies or publish anything you paste.
