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
