Plainvoice vs Humanizeo

Plainvoice says you lock a phrase and that phrase stays as written. The original sits beside the rewrite. Changed spans are marked. The word-count change is printed under the pair. The line under the rewrite is an estimate, not a detector. The saved blog note keeps 18% and drops “It is important to note that ” and “Furthermore, ”.

Not a phrase you type into a lock list. The site says facts, numbers, brand names, and links are kept verbatim, and that must-keep keywords stay character for character. Its paraphrasing page says numbers, proper nouns, and links are protected automatically.

The paraphrasing page says numbers, proper nouns, and links are protected automatically. The home page also says you can add must-keep keywords. Whether every fact is chosen for you, with no keyword list, is not stated.

Plainvoice does not scan the draft and decide which facts matter. You do. The panel is labeled Keep these words. You add the price, the date, the name, the time, or the quoted line. One lock highlights that phrase. Several locks each stay character for character. The × removes the lock only. Those words stay in the draft, and the next rewrite may reword them if you leave them unlocked.

If 42 pallets, Maya Chen, 14:00, and PO-4418 must survive a client email, you lock those four strings yourself. The stored client rewrite keeps them. Output languages are English, Dutch, Spanish, French, German. The draft can be in a different language. A locked phrase is not translated.

The newsletter sample locks 86 people, 09:00, and March, and the blog sample locks 18%. One request stops at 400 words on every plan. A longer guide is how to rewrite AI text and keep every fact.

Plainvoice does not promise that a rewrite will pass a detector. It does not sell a detector score. The estimate under a rewrite is an estimate of the writing in front of you. The home page line is “Estimate. Not a detector.”

The site says no tool can promise 100% on detectors. It also says the loop rewrites until its own detector scores the text clearly human.
