WHAT TO EXPECT

What Our AI Detector Can (and Can't) Tell You

AI detection is helpful — but it's not a lie detector. Use it as a signal, not a verdict.

It can help you:

  • spot patterns common in AI‑assisted writing (repetition, unnatural cadence, generic phrasing)
  • review drafts faster before publishing or submitting
  • identify sections that may benefit from rewriting

It can't:

  • prove authorship with certainty
  • replace human judgment , editorial review, or institutional policies
  • guarantee "AI vs human" accuracy in every case
