Quality discussion

CleanerTone emphasizes free ai humanizer positioned as a professional writing tool. StealthGPT emphasizes stealth-oriented ai writing / humanizer brand. On naturalness, CleanerTone leads our dimension score (8.6/10). 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. Marketing cites GPTZero, Turnitin, Originality.ai and “99.9% accuracy.” Quoted as claims only. Meanwhile: Stealth claims are marketing; validate independently.
