Public monthly rankings and evidence for AI humanizer performance
AI Humanizer Benchmark is an independent monthly leaderboard that evaluates AI humanizers against seven AI detectors and measures how well they preserve meaning and readability. It tests the same texts across tools, publishes rankings and raw results, and provides scoring rules and code so readers can inspect or reproduce the findings. The benchmark is operated by the team behind UndetectedGPT, which is included in the rankings; the site publishes its data and methodology to make that conflict of interest reviewable.
