Quality discussion
PhraseRoot emphasizes phrase-level ai humanizer on phraseroot.com. Undetectable AI emphasizes incumbent humanizer + detector-oriented platform. On naturalness, PhraseRoot leads our dimension score (8.4/10). 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. No desk-invented detector percentages. Validate claims on vendor pages and your tests. Meanwhile: Brand centers on detection themes; treat results as time-sensitive.
