What users say

Pros

  • Idiosyncratic phrasing and distinctive pre-AI stylistic habits reliably score as fully human.
  • Caught text that ZeroGPT and QuillBot both scored at 0% AI, and that many humanizer tools failed to disguise.

Cons

  • Scores can swing between runs and on short or partial texts.
  • AI text written in an unusual style or lightly edited can pass as human.
  • Checking long documents or many posts gets costly once the free scans run out.
