Frequently Asked Questions

Still got questions about our ChatGPT detector? Here are the answers.

A ChatGPT AI detector is an online tool designed to analyze text and determine if it was generated by artificial intelligence. It evaluates sentence structures to provide a percentage score indicating how much of the content is likely AI-generated, mixed, or written entirely by a human.

Our ChatGPT detector analyzes the text structure and word choices to identify patterns common in AI outputs. It compares your document against known language models like GPT-3.5 and GPT-4 to calculate the probability of AI generation. The tool then highlights specific sentences that match these AI patterns.

While highly accurate for GPT-3.5 and GPT-4 outputs, false positives can occasionally occur. The detection serves as a strong signal rather than absolute proof. We recommend using the report as a starting point for further review, especially for academic or professional evaluations.

No. We do not store your documents or use your submitted text to train our models. All data is processed securely and immediately discarded.
