HumanizerBench

Monthly, reproducible rankings of AI humanizers tested against six AI detectors

Six-detector testing

Leading AI humanizers are scored against GPTZero, ZeroGPT, Copyleaks, Winston AI, Originality.ai and Pangram using identical prompts every cycle.

Weighted composite scoring

The overall figure blends bypass rate, meaning preservation, readability and consistency, with explicit deductions for failures like unchanged output or meaning drift.

Category-level results

Prompts span academic essays, application essays, blog posts, business email, marketing copy, discussion boards and news articles to expose uneven performance.

Full reproducibility

Every prompt, raw output and detector verdict is published with the scoring script, a JSON endpoint and a GitHub repo.

Strengths & Pros

+Detector-verdict based rankings instead of marketing claims
+Publishes raw prompts, outputs, verdicts and the scoring script for reproduction
+Scores meaning, readability and consistency alongside bypass rate
+Archived monthly cycles reveal whether a tool is consistently strong or erratic
