Methodology & provenance

October 2026 overall scores are source-reported aggregate values. The source publishes bypass, meaning, readability, factual accuracy and length stability, but does not publish consistency scores, scoring weights, penalty rules or the underlying formula. Humanizer Arena preserves the supplied overall scores and does not recalculate them. Per-detector and per-category breakdowns are reported separately so you can match a tool to your actual need.
