Detection performance
WriteHuman AI: One of the more heavily marketed student-focused tools, though third-party detector testing found inconsistent results even on the paid tier.
WriteBros.ai: Achieved a 100% human GPTZero score in testing, but only after four iterative rewriting rounds rather than a single pass.
AI detector included: Neither tool bundles a built-in detector — pair either with GPTZero or Originality.ai.
