Humanize AI Pro vs WriteHuman
HumanFlow is not one of the two tools on this page. We make a competing product, so weigh this accordingly — our methodology sets out how we source competitor figures and what we refuse to claim.
Neither of these can be bought for a single month. Both entry plans are annual, so the first question is not which is cheaper but which year you want to own.

Why people compare these two
They are close competitors on positioning — both dedicated humanizers, both pitched below the best-known names, both landing on the same comparison lists. Anyone weighing them is usually choosing a first paid humanizer rather than switching from one.
That makes the shared commitment structure more important than it looks. Neither company publishes a month-to-month rate at entry, so whichever you choose, the decision is a year long and has to be made on published specifications rather than on experience.

Humanize AI Pro figures read from their pricing page on 16 August 2026; WriteHuman from theirs on 4 August 2026.
What actually separates them
Humanize AI Pro is $5.83 a month billed annually for 20,000 words, capped at 500 words a paste. WriteHuman is $12 a month billed annually for 80 requests, capped at 600 words each.
Those units do not convert without an assumption about you. Fill every WriteHuman request to 600 words and it is 48,000 words for the year's money; spend them on short fixes and the same subscription yields a fraction of that, because a request costs a request regardless of what you put in it. Humanize AI Pro's 20,000 words are 20,000 words however you spend them.
So the comparison rests on how evenly you write. Consistent long passes favour WriteHuman on raw capacity. Irregular work, or a lot of small revisions, favours the tool that meters the thing you are actually consuming — and at less than half the price.
The per-request caps are near enough identical, 500 against 600, and both are below the length of a standard essay. Neither tool takes 1,500 words in one pass at entry, whatever the annual capacity suggests, so on both you are reassembling a document from pieces that were rewritten without sight of each other.
The extras run in opposite directions. Humanize AI Pro includes a Chrome extension on every plan, the free one included, which is unusual at this price and useful if you want rewriting where you already type. WriteHuman scans images on every paid plan and returns two output variations at entry rising to five at the top tier, so you choose between rewrites rather than accepting the first.
Their free tiers are both too small to answer anything: 500 words once at 100 words a time, against 3 requests at 250 words. Between them that is well under a single essay, which is another way of saying the year-long decision has to be made on the specifications above.
Which to pick
Pick Humanize AI Pro if you write in bursts, revise in small pieces, or simply want the lower annual commitment — it is less than half the price for a word allowance that does not punish short edits. The extension on every tier is a real advantage if you draft in the browser.
Pick WriteHuman if you write in long, even passes that fill 600-word requests, or you want several versions to choose between and image scanning included. Used that way it buys more capacity than the price implies; used any other way it does not.
The claim we won't compare on
Neither tool's ability to get text past an AI detector appears above, and it is not an oversight. No vendor can observe or control the systems such a claim is about, detectors change without notice and disagree with each other on identical text, and every published bypass rate in this category was produced by the company selling the tool it tested. We publish none for our own product either — see why we publish no bypass rates.
