StealthWriter

The rewrite is not a single button. The detector marks the sentences it flags, and each one can be swapped for an alternative you pick, at an intensity you set from light to heavy. That turns the tool into an editing loop rather than a black box, and it is why this beats a paste-and-pray rewriter: you keep the sentences that already say what you mean and only change the ones that read as machine-made. The vendor's own guidance is consistent with that — light levels change little, heavy levels rewrite a great deal — and a draft with real content in it usually wants the light end.

The before-and-after numbers come from StealthWriter's own detector, which makes them a measure of how this tool reads its own output. That is genuinely useful as a working signal inside the editing loop, and it is not the same as verification by an unrelated system. The vendor is also careful in one direction and less careful in another: it states plainly that submitted text is not stored after processing, not shared and not used for training, which is the sentence that matters most for unpublished work, while its marketing makes broader claims about detection outcomes that nothing here can test.

Commercially it is the day that governs. Every tier is rationed per day — ten rewrites free, fifty on Starter at $20, up to two thousand on Scale at $400 — and input length steps from 1,000 words on Free to 5,000 on everything paid. Nothing above Starter adds a capability; the ladder from $50 to $400 buys daily volume and faster support. So the plan you need is set by your busiest day rather than your monthly total, which is an unusual way round and worth modelling before you subscribe. Note too that paid plans renew automatically unless cancelled before the renewal date, and that the payment policy hands refunds off to a document of their own.
