Our verdict

Editor's assessment

Undetectable AI is the stronger overall performer in this matchup. Its bypass rate (94.1%) is higher than Bypass AI's (78.2%), and it wins against 3 of the 5 detectors where there is a clear winner. The 8-point penalty for length inflation is a real issue, but even with that hit, Undetectable AI still finishes 3.3 points ahead on overall score.

Bypass AI is not a bad tool. It holds a meaningful advantage against Copyleaks and Originality.ai, which matters for users who specifically need to beat Turnitin (which uses Originality.ai's detection engine).

For most use cases, Undetectable AI is the better pick. The exception is workflows that specifically target Copyleaks or Originality.ai, where Bypass AI's advantage gives it a genuine edge.
