Frequently Asked Questions

Everything you need to know about AI text detection and our tool.

Our tool uses heuristic analysis based on linguistic patterns — not machine learning models. Results are estimates and work best with longer text (100+ words). For critical decisions, combine our results with human review and professional plagiarism tools.
No. All analysis runs entirely in your browser using JavaScript. Your text never leaves your device, making ChatGPT Detector safe for confidential essays, emails, and business documents.
