AI Humanizer Benchmark is a free comparison site, not a writing tool. Each month it runs 10 AI humanizers on the same 33 AI-written texts, using each tool's default settings, and checks the output with GPTZero, Originality.ai, Copyleaks, Pangram, ZeroGPT, QuillBot and Grammarly.
Scores are out of 100 and combine bypass rate (42%), meaning preservation (32%), readability (16%) and consistency across writing types (10%), with penalties for problems like meaning drift or near-identical output. The November 2026 cycle ranks CleverHumanizer first with 79.33, followed by UndetectedGPT and Rephrasy.
- Access: The rankings, methodology and raw data are free to view with no sign-up mentioned on the site.
- Paying for tools: The site does not list prices or Pakistani payment options for the humanizers. Check each tool's own pricing page before paying, and confirm card or local payment support directly with the vendor.
