Every prompt, output, and detector score is published.

Benchmark results
WriteHuman finished first; Clever AI Humanizer finished fourth
HumanizerBench is a public monthly benchmark of AI humanizers. It runs every tool by hand on the same prompts and publishes its inputs, outputs, and detector scores so the results can be checked. The October 2026 cycle ran 420 tests across fourteen humanizers and six AI detectors, and scored every output on the average of all six verdicts. WriteHuman finished first for the fourth cycle in a row with a composite of 74.89. Clever AI Humanizer finished fourth at 69.02, almost six points behind.
On the detectors, WriteHuman posted the highest GPTZero, Winston AI, and Originality.ai pass rates of all fourteen humanizers: 99.5%, 100.0%, and 100.0%, against Clever's 91.4%, 91.8%, and 97.1%. The widest gap was ZeroGPT, where WriteHuman's output passed 89.5% of the time and Clever's 76.9%. Averaged across all six detectors, WriteHuman's output read as human-written 88.8% of the time, against 80.1% for Clever.

Meaning drift
Clever's rewrites can say the opposite of what you wrote
HumanizerBench takes points off when a rewrite strays from what the original said. Clever AI Humanizer lost 4 points that way in October. WriteHuman lost none.
The slips are easy to miss because they read smoothly. In a blog post about mechanical keyboards, a tip warning that steep keyboards leave your wrists bent came back saying a sloped keyboard may help your posture and suits long typing sessions, which is the opposite advice. In a discussion post arguing that public art is not a frivolous add-on, Clever's version turned the point into a complaint about what art costs. Publish a rewrite like that and you are making claims you never made.
Clever also gives you a single rewrite per request. If it changes a sentence it should have left alone, your only option is to run the whole text again and hope. WriteHuman's paid plans return multiple variations at once, so you keep the one that held on to your meaning and move on.

Formatting
Your headings and bullet lists come back intact
Clever AI Humanizer turned bulleted lists into plain paragraphs in every benchmark sample that had them, and kept only 4 of 17 headlines intact. WriteHuman kept 16 of 17. On one landing page Clever lowercased the product's brand name throughout and reworded a customer testimonial that should have stayed word for word. Its blog rewrites also came back about 25% longer than the original, against about 3% for WriteHuman, so anything written to a word count needs trimming afterward.
For a landing page, a structured report, or a blog post with subheadings, that means rebuilding the layout by hand after every pass. WriteHuman is built to keep your structure, so a draft with headings and lists comes back as a draft with headings and lists, ready to publish.

Content types
WriteHuman scored higher on every content type in the comparison
The benchmark also breaks results out by the kind of writing. WriteHuman scored higher than Clever AI Humanizer on all four of the content types in the comparison above: blog posts (84.7% vs 76.7%), news articles (99.2% vs 88.9%), marketing copy (88.2% vs 75.2%), and discussion posts (93.2% vs 89.8%).
Marketing copy is where the gap is widest, 13 points, and it is the copy most likely to be checked before it goes live. Add the lost headings, the lowercased brand name, and the reworded testimonial, and landing pages and product pages come out of Clever needing the most repair.
