Why people look for a StealthWriter alternative
StealthWriter is a capable tool — this page is about fit, not fault. If it works for you, keep it.
Where ClearPen comes in
ClearPen is a focused humanizer with a built-in detector, organized around protecting legitimate writing from false positives. It uses a monthly word allowance instead of daily caps and offers a dedicated Academic tone. StealthWriter still wins if you specifically want granular, sentence-by-sentence rewrite selection — that's its strength.

The honest way to decide
No humanizer can promise a specific score on every detector — the models change constantly. The realistic test is to run the same paragraph through both tools and check it with a built-in AI detector before you submit. ClearPen's humanizer shows your before/after score in the same place so you can see what actually changed.
