Monthly, reproducible rankings of AI humanizers tested against six AI detectors
Leading AI humanizers are scored against GPTZero, ZeroGPT, Copyleaks, Winston AI, Originality.ai and Pangram using identical prompts every cycle.
The overall figure blends bypass rate, meaning preservation, readability and consistency, with explicit deductions for failures like unchanged output or meaning drift.
Prompts span academic essays, application essays, blog posts, business email, marketing copy, discussion boards and news articles to expose uneven performance.
Every prompt, raw output and detector verdict is published with the scoring script, a JSON endpoint and a GitHub repo.
