Output Quality: how Neonhumanizer and StealthWriter actually differ

For email outreach, that means StealthWriter suits writers who want to approve changes sentence by sentence, and Neonhumanizer suits SDRs and founders chasing replies who cannot afford drift in the final draft.

StealthWriter's approach to email outreach reflects its category (sentence-level humanizer): showing alternative phrasings per sentence in a visual editor is the headline, and for some workflows that is exactly right. The catch documented across independent testing: readability scores lag its raw bypass numbers in independent tests. For output quality, weigh that against how often you'd hit it in real email outreach work.
