Quality discussion

HumanifyLab emphasizes lab-styled ai humanizer — separate from humanifyer. Undetectable AI emphasizes incumbent humanizer + detector-oriented platform. On naturalness, HumanifyLab leads our dimension score (8.3/10). Still run your own 300–500 word sample — genre fit matters more than a single composite.

Detector evidence remains limited for public citation on both sides. Quote vendor pages carefully; no fabricated lab charts on this desk. Meanwhile: Brand centers on detection themes; treat results as time-sensitive.
