Benchmark results

First place overall, and ahead of AI Humanize io on every sub-score

HumanizerBench is a public monthly benchmark of AI humanizers. It pays for every tool, runs each one by hand on the same prompts, and publishes all inputs, outputs, and detector scores so the results can be checked. In the August 2026 cycle — 33 samples per tool, 396 tests, five detectors — WriteHuman finished first of the twelve humanizers with a composite of 76.69. AI Humanize io placed sixth at 64.57.

That lead is not one number carrying the scorecard. WriteHuman scored higher on all four graded sub-scores in the same cycle: AI-detector pass rate (89.1% vs 70.8%), meaning preservation (71.7% vs 64.4%), readability (57.8% vs 54.6%), and consistency across writing types (80.8% vs 74.7%), and it took fewer quality deductions (-1 vs -2). The full numbers are shown in the comparison above and on HumanizerBench itself.

Detector scores

A higher pass rate, and four of the five detectors

Every rewrite in the benchmark is scored against five commercial AI detectors. In the August 2026 cycle, WriteHuman's output passed 89.1% of those checks to AI Humanize io's 70.8%, and WriteHuman scored higher on four of the five detectors.

The widest splits are on GPTZero, where WriteHuman scored 88.4% to AI Humanize io's 54.4%, and Originality.ai, at 66.5% to 40.1%. WriteHuman also came out ahead on Winston AI (83.8% vs 80.7%) and Copyleaks (67.1% vs 63.7%). Detectors disagree with each other constantly, which is why WriteHuman puts its own detector in the same view as the humanizer: you check the text against a score before you publish instead of guessing which checker your reader will run.

Marketing copy runs 97.1% to 82.7%, and news articles — the toughest of the four for both tools — 61.7% to 48.6%.
