Plainvoice vs StealthWriter

Plainvoice rewrites the wording, locks the facts you choose, and shows the original beside the rewrite. It does not promise that a rewrite will pass a detector, and it does not sell a score that says so.

StealthWriter asks you to paste AI-generated text, choose a rewrite level, and click Humanize. Its FAQ says there is no download.

Not stated as a promise that a rewrite will pass a detector. The site includes an AI detector and says you can scan before and after you humanize.

Not stated. The FAQ says a rewrite preserves the original meaning and key points. It does not describe a lock on a number or a name.

You choose the phrase. The panel is labeled Keep these words. A price stays a price, a time stays a time, and a quoted line stays inside its quotation marks. The × removes the lock only. The original sits beside the rewrite, changed spans are marked, and the word-count change is under the pair. One request stops at 400 words on every plan. A paragraph retry meters only that paragraph.

Output languages are English, Dutch, Spanish, French, and German. A locked phrase is not translated. Free does not include a saved style profile. Writer includes 1. Studio includes 5. The profile does not relax a lock. The client email walk-through is on client emails.

Free is $0 and needs no card. The home page lists 10 humanizations a day, 10 AI scans a day, and 1,000 words per input. The pricing page lists the same daily counts and Ghost 5.2 Mini on Free.

Starter is $20 a month (the FAQ also says $200 a year): 50 humanizations a day, 50 scans a day, and 5,000 words per input.

The pricing page also lists Business at $200 a month and Scale at $400 a month. Daily humanization counts for Business were not in the pricing-page text that was retrieved, so they are not stated. The home page FAQ says Scale is 2,000 humanizations a day, or $4,000 a year.

Its FAQ says it is for writers, marketers, copywriters, researchers, and professionals who use AI to draft and want the result to read naturally. It also says to follow an employer or school policy and not to misrepresent authorship.

A side-by-side original and rewrite is not stated. Not stated as a text diff. The site shows a detector score and color-coded sentence highlights. Whether it locks a number or a name is not stated.
