AI-pattern score

This is our own AI-pattern score, measured here on sentence rhythm, template phrases, vocabulary variety and passive voice. It is not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT result, and it does not predict one. Worth knowing: we also ask the rewrite to vary sentence length, drop template phrases and prefer the active voice, so some of the drop is built in. Read the two panels below, not just the number.

WriteHuman costs $18, $27 or $48 a month, or $12, $18 or $36 a month if you pay for the year. It is metered by requests rather than words, which is the thing that decides whether it fits you. Its top tier advertises "Unlimited requests" and caps every single one of them at 3,000 words. Every figure below was read on writehuman.ai/pricing on August 25, 2026, across three identical loads.

Almost every humanizer in this market sells you a monthly word allowance. WriteHuman sells you a number of attempts. That sounds like a small difference and it is the difference between a plan that suits you and one that runs out in the second week, because the two models fail in opposite directions.

What does "unlimited requests" mean on WriteHuman?

It means unlimited attempts, each one capped at 3,000 words. Ultra removes the count and keeps the size limit, so a 12,000-word report is still four separate submissions; you just will not be charged for having made them. That is a real benefit if you rewrite constantly and a smaller one than the word "unlimited" suggests if your problem is document length.

There is a second thing worth noticing on that tier. Ultra's feature list reads "MCP access (1,000/mo)" while Basic and Pro read "MCP access" with no figure, and the comparison table shows MCP as available only on Ultra, capped at 1,000 a month. So the plan called Unlimited is the one with a numbered ceiling on its newest feature. Neither reading is dishonest, they are just two different meters wearing one adjective, and it is the kind of detail that only matters after you have paid.

Requests or words: which metering model should you buy?

Work out your average job size first, then divide. That single calculation tells you more than any review will.

If you rewrite many short things, request-metering punishes you. Two hundred requests on Pro sounds generous until you are rewriting forty product descriptions of 150 words each, at which point you have spent forty requests to move 6,000 words. A word-metered plan would have charged you 6,000 words and left the rest of the month intact. On WriteHuman you have used a fifth of your allowance on a morning's work.

If you rewrite a few long things, request-metering rewards you heavily. Two hundred requests at up to 1,200 words each is a theoretical ceiling of 240,000 words a month for $216 a year, which works out around seven and a half cents per thousand words at full use. Nothing else in this category is close to that rate. The catch is that the ceiling is only real if every request is nearly full, and most people's are not.

Basic is the plan this arithmetic condemns. Eighty requests at up to 600 words is a ceiling of 48,000 words for $144 a year, about twenty-five cents per thousand. Pro costs $72 more a year and triples the effective ceiling, so it is more than three times better value per word. If you are choosing between Basic and Pro on price, the honest answer is that Basic is the expensive one.

Is the WriteHuman free plan enough to test it?

Three requests a month at up to 250 words each is 750 words of testing, and then you wait until the next billing cycle. That is one of the tightest free tiers in the category, and it is tight in the way that matters most: three attempts means three tries. If the first rewrite comes back wrong and you want to test a different input, you have spent a third of your month finding that out.

Spend those three deliberately. Use a paragraph you wrote yourself and know well, and read the output for meaning rather than style. The failure that matters here is not clumsy prose, it is a rewrite that quietly drops a qualifier, softens a claim or swaps a technical term for a near-synonym that means something else. That shows up in the first 200 words if it is going to show up at all. Rivals are more generous at this stage, and we put every vendor's trial terms side by side in this comparison of AI humanizer free trials.

What about the built-in AI detector?

Every WriteHuman plan includes "AI detection checks", and this is the feature to be most careful with, for a structural reason rather than a suspicious one. When the company that writes the rewrite also writes the score, the rewriter is being tuned against the thing that grades it. The result reliably passes its own exam. That tells you the rewrite happened; it tells you nothing about what Turnitin, GPTZero or Originality.ai will say next month, because those are different models with different training data and different thresholds, and they change without announcing it.

Use any in-house checker the way you would use a spellchecker: as a signal that the tool did something, never as evidence. If you want to understand what the third-party classifiers are actually measuring, we set out the mechanism in how AI detectors work, including the widely misread fact that a "90% AI" result is a confidence figure and not a percentage of your document.

WriteHuman is the most expensive entry ticket in that table, at $144 a year against Undetectable.ai's $60 and Humbot's $81.48. What it buys you is the highest theoretical word ceiling per dollar of anything here, provided your documents are long enough to fill the requests. It is a plan shaped for people who write in long pieces, and it is a poor deal for people who write in short ones.

One genuine credit worth giving: WriteHuman publishes its monthly and annual prices in the same table, on the same page, with the annual savings named. Most of this category shows you a monthly-looking figure that is really the annual rate and leaves you to discover the difference at checkout. Humbot's top tier, for instance, is $8.49 a month on the annual tab and $50.99 a month if you pay monthly, a six-fold gap we worked through in our Humbot AI humanizer review. WriteHuman does not do that to you, and in a market with this many billing complaints that is worth something.

Is WriteHuman worth it?

Buy Pro if you write long-form and want the best rate in this comparison; at up to 1,200 words a request and 200 requests a month it is the value tier by a distance, and Basic is the one to avoid. Buy Ultra if you rewrite constantly and want to stop counting, accepting that 3,000 words is still the size of a single job. Skip WriteHuman entirely if your work is many short pieces, because request-metering will charge you a full attempt for every 150-word paragraph and a word-metered plan will not.

One more consideration that has nothing to do with price. Any humanizer is a tool for text you have already decided to rewrite. If your situation is that something you genuinely wrote got flagged, rewriting it is the wrong move and can make your position worse; that is a documentation problem, not a text problem, and we set out what actually helps in how to prove you did not use AI. For freelancers pricing this against what the work brings in, the calculation is really about what an hour of your rewriting time is worth, which is the same arithmetic behind building a roster of paying writing clients in the first place, and it usually argues for the tier above the one you were going to pick. If you are weighing a subscription against negotiating a better rate on the work itself, an AI salary negotiation coach is the cheaper lever of the two.

The short version

WriteHuman is a request-metered humanizer at $144 to $432 a year, or $18 to $48 a month if you will not commit. Pro at $216 a year is the tier that makes sense for most buyers. "Unlimited requests" on Ultra means unlimited 3,000-word jobs, not unlimited words. The free plan gives you three attempts a month, which is enough to check whether the rewrite preserves your meaning and not much else. And whatever its built-in detector tells you about your output, treat it as a sign the tool ran, not as evidence about what any third-party detector will say.

Prices in this category move, and they moved twice on tools we track this month alone. Everything here was read first-party on August 25, 2026. Check the vendor's own page before you pay.
