What our research says

Humanize Max

Everything free with no signup is rare enough in this category to be the main reason to try it, and term locking is a genuinely practical touch when brand names would otherwise get paraphrased away. The flip side is that a tool with no revenue model and no named operator gives you nothing to rely on if it changes or disappears.

Pros

Every feature free with no rerun limit and up to 2,000 words a pass
No account or sign-up required
Four writing styles plus shorten and expand control
Term locking keeps chosen words intact

Cons

No company or country identified anywhere
No API and no team features
No stated revenue model, so longevity is unclear

StealthWriter

Pairing the rewriter with its own detector in one screen is the sensible design choice here — you can see the before and after score instead of pasting into a third tool to find out. The tiering is honest about what you are buying: daily rewrite count and input length, nothing hidden. Everything else about this category applies, though: detector scores are not a guarantee, the rewrite flattens voice and sometimes meaning, and using it on assessed work is a disciplinary matter regardless of what the score says.

Pros

Built-in detector scores text before and after the rewrite in the same interface
Free tier is a standing 10 rewrites a day, not a one-off trial
Every paid tier raises input length to 5,000 words, so tiers differ only by volume
Named US operator with published phone and email support hours
Changelog actively maintained, indicating ongoing development

Cons

Detector evasion degrades as detectors update — today's score is not a durable result
Rewriting flattens voice and can quietly alter facts or technical terms
$400/month top tier is steep for a single-function tool, and there is no API to justify it
Free tier's 1,000-word input cap excludes most real articles
