What the scores mean
- Source-reported overall
- The overall score each tool is ranked by, as reported by the source. It's preserved as published and not recalculated. Higher is better.
- Bypass
- The share of rewritten outputs that AI detectors didn't flag, across the detector panel.
- Meaning
- How well the rewrite keeps the original's meaning, claims and argument intact.
- Readability
- How naturally and fluently the output reads to a human.
Limitations
These scores describe how each tool performed in one benchmark cycle, on our test set and detector panel. They aren't a guarantee for any individual document.
