Visit AI Humanizer Benchmark

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.

Key features

  • Monthly ranking of 10 AI humanizers
  • Tests against 7 commercial AI detectors
  • Overall score with bypass, meaning, readability and consistency
  • Category views such as essays, students, SEO and marketing
  • Penalty system for identical output, refusals and length changes
  • Full inputs, outputs and scoring code published on GitHub

Pros

  • Free to access, with all raw data and scoring code public for checking
  • Uses the same texts, detectors and formula for every tool, so the comparison is consistent
  • Measures meaning and readability as well as detector bypass, which catches tools that ruin the text
  • Discloses that the team runs UndetectedGPT, which is included in the rankings

Cons

  • The site's own team builds UndetectedGPT, which ranks second, so readers should weigh that result carefully
  • Each month uses only 33 texts and default settings, which may not match how a user would configure a tool
  • Detector results can change as detectors update, and Turnitin is not tested directly, only approximated by Originality.ai
