Quality discussion

PhraseRoot emphasizes phrase-level ai humanizer on phraseroot.com. StealthGPT emphasizes stealth-oriented ai writing / humanizer brand. 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: Stealth claims are marketing; validate independently.
