Quality discussion
RewritEssay emphasizes essay-oriented ai rewriting / humanizer. Undetectable AI emphasizes incumbent humanizer + detector-oriented platform. On naturalness, RewritEssay 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. Vendor marketing may reference academic detectors; not desk-certified. Meanwhile: Brand centers on detection themes; treat results as time-sensitive.
