Our verdict
Editor's assessment
Humbot AI is the stronger overall performer in this matchup. and it wins against 2 of the 5 detectors where there is a clear winner. It finishes 0.2 points ahead on overall score.
Undetectable AI is not a bad tool. It holds a meaningful advantage against GPTZero and Proofademic and ZeroGPT. However, its penalty load of 8 points (length inflation) is significant, meaning it is more likely to alter what your text actually says.
For most use cases, Humbot AI is the better pick. The exception is workflows that specifically target GPTZero or Proofademic or ZeroGPT, where Undetectable AI's advantage gives it a genuine edge.
