Gold, silver and bronze mark the top three scores in each column. Tied scores share a color.
Showing scores in the Overall column ( prompts per humanizer this cycle). A test only earns bypass credit when its output is a real rewrite; that is blended with the category's own meaning and readability. Small categories swing; that's the point. How category scores work

How scores are computed
Full methodology- Bypass
- Share of detector tests where the output was classified as human.
- Meaning
- How well the output preserves the original meaning.
- Readability
- How clear, fluent, and natural the writing reads, rated by a language model.
- Consistency
- How evenly the humanizer performs across writing categories.
Penalties
Taken off the total for each flagged test. Each rule stops at −10.0, −50.0 in total, and a score cannot go below 0.
- Identical to input −2.0
- The tool returned the input mostly unchanged. No real humanization happened.
- Refusal −1.0
- The tool refused to humanize the input, often due to a content-policy block.
- Meaning drift −1.0
- The output's meaning drifted significantly from the original input.
- Length inflation −1.0
- The output ran much longer than the input, a common trick that pads text to dilute the AI signal.
- Length deflation −1.0
- The output came back much shorter than the input. The rewrite dropped content instead of paraphrasing it.
