Frequently Asked Questions
Which AI models can this detector identify?
Our AI detector is trained to identify text generated by major AI models including ChatGPT (GPT-3.5 and GPT-4), Claude (Anthropic), Google Gemini, Microsoft Copilot, and LLaMA-based models.
How accurate is the AI content detector?
The detector achieves high accuracy on clearly AI-generated content. However, heavily edited AI text or short passages may be harder to classify with certainty. We recommend it as a strong indicator rather than an absolute verdict.
Is my text stored or shared?
No. Your submitted text is processed for analysis and immediately discarded. We do not store, log, or share any text submitted to the detector.
Can teachers and professors use this to check student work?
Yes. The tool is widely used by educators to check for AI-generated submissions. Paste the student's text and receive an instant AI probability score.
Is this tool completely free?
Yes, 100% free. There are no word limits, no API keys required, and no subscription plans. You can check as many texts as needed.
What score means the text is AI-written?
A score above 70% indicates likely AI-generated content. Scores above 90% are very strong indicators. Scores below 30% suggest human-written text.
