How we can help you as a

No. Your text is used only to generate your AI detection report and is not sold or shared with third parties for their own purposes. We handle your content securely and explain how we use data in our Privacy Policy.

A false-positive means human-written text is flagged as AI-generated. A false-negative means AI-generated text is missed. No detector is perfect—use probability levels and review highlighted sections before making decisions.

Start with your ideas, then refine flagged sections with Paraphrase or Humanize so phrasing sounds like you. Edit tone, examples, and transitions manually—small personal details are what make writing unmistakably yours.

Our AI detector flags text that may be AI-generated. Use your best judgment when reviewing results. Never rely on AI detection alone to make decisions that could impact someone's career or academic standing.
