Frequently Asked Questions
How accurate is the AI detector?
Our tool uses advanced detection algorithms trained on millions of human and AI-written texts. While no AI detector is 100% accurate, our technology provides reliable detection across various content types.
What is perplexity and burstiness?
Perplexity measures how predictable text is - AI writing tends to have low perplexity. Burstiness measures variation in sentence structure - humans write with more variation. Together, these metrics help identify AI-generated content.
Can I use this tool for plagiarism detection?
This tool specifically detects AI-generated content, not plagiarism. If you're looking to detect copied content from other sources, you'll need a dedicated plagiarism checker.
Is my content stored or shared?
No. The text you analyze is processed for detection but is not stored or shared. We do not retain analyzed documents.
