Rewritify AI review of pricing, word caps and the yearly plan nobody should buy
Rewritify sells three plans. On yearly billing, two of them cost exactly the same $16 a month, and one of those two gives you a tenth of the words. Here is the full ladder, dated, plus the paste limit that decides whether the cheap plan can take your document at all.

The short answer
Rewritify is a web-only AI humanizer with a built-in detector, priced at $14, $24 or $49 a month in USD, or $9, $16 and $16 a month billed yearly. The yearly column is the whole story: because the annual discounts are uneven, at 36%, 33% and 67%, the top Unlimited tier lands on exactly the same $16 as the middle Ultimate tier while giving you unlimited words instead of 50,000 and removing the 3,000 word per-paste ceiling that Basic and Ultimate both carry. Yearly Ultimate is therefore strictly worse than yearly Unlimited at an identical price, and there is no reason to choose it. The free allowance is 80 words on signup, which is a sample rather than a plan, and the refund window closes after three days or 1,000 words, whichever comes first. There is no API and no browser extension.

The ladder
Rewritify pricing, with both word limits shown side by side
Three tiers, two different caps, and one yearly price that appears twice. Every figure read September 6, 2026.
| Plan | Monthly | Billed yearly | Words per month | Words per input | Yearly saving |
|---|---|---|---|---|---|
| Basic | $14/mo | $9/mo | 5,000 words/month | 3,000 words | 36% off monthly |
| Ultimate | $24/mo | $16/mo | 50,000 words/month | 3,000 words | 33% off monthly |
| Unlimited | $49/mo | $16/mo | Unlimited | Unlimited | 67% off monthly |
Read the monthly column on its own and the ladder is completely ordinary: $14, then $24, then $49, with each step buying roughly what you would expect it to buy. Nothing in that column would make anybody look twice, and it is the column most write-ups of this product reproduce.
Read the yearly column and the ladder stops being a ladder. Basic drops 36%, Ultimate drops 33%, and Unlimited drops 67%, which is a much steeper cut than either of the tiers beneath it. The arithmetic of those three different discounts lands Unlimited on $16 and Ultimate on $16 as well. Two plans, one price, and the cheaper-looking one is the smaller product.
It matters more than a curiosity because of the default. Open rewritify.ai/pricing and the Yearly toggle is already selected, with a "Save 67%" badge sitting on the Unlimited card. The prices a first-time visitor sees are $9, $16 and $16, in that visual order across the page, and the two identical numbers are on cards of different sizes at opposite ends of the row. It is easy to read that as a normal ladder and pick the middle one out of habit.
The one thing to know
On yearly billing, the Ultimate plan is strictly worse than Unlimited at the same price
Put the two $16 plans next to each other and every single line favours one of them. Ultimate gives 50,000 words a month; Unlimited gives no monthly limit. Ultimate caps each submission at 3,000 words; Unlimited caps nothing. Ultimate's card lists eight feature bullets; Unlimited's lists the same eight plus "Improved readability and clarity". There is no dimension on which Ultimate returns something Unlimited withholds.
In pricing terms that makes Ultimate a dominated option on annual billing. Buying it is paying full price for a strictly smaller version of the thing sitting beside it. This is not a hidden fee or a dark pattern, and it is worth being fair about that: the numbers are printed plainly on the page and nobody is concealing anything. It is simply what happens when three tiers get three different discount percentages and the largest discount is applied to the top one.
The practical instruction is short. If you are buying Rewritify annually, buy Unlimited. If the middle tier is the one that fits your budget, the middle tier costs the same as the top tier, so buy the top tier. The only situation in which Ultimate makes sense is monthly billing, where it genuinely is $25 a month cheaper than Unlimited and the ordinary trade-off applies again.
What the yearly commitment actually is
A $16 a month yearly plan is a $192 decision taken once, not a $16 decision taken twelve times. Set that against the refund terms below, which give you three days and 1,000 words to change your mind, and the honest way to approach this product is to spend the 80 free words and then a month at full monthly price before committing a year. The annual saving is real, but it is a saving you can still capture in five weeks' time with better information.
The cap people search for
The 3,000 word paste ceiling, and why the cheap plan may not fit your document
Rewritify enforces two limits that are easy to confuse. One is the monthly allowance, the pool of words your subscription entitles you to over a billing period. The other is the per-input cap, the most you may put into a single submission. Basic and Ultimate both print "Humanize up to 3,000 words per input" on their cards, and that figure does not move when you pay more. It moves only when you reach Unlimited, where it disappears entirely.
So the two tiers differ in pool size by a factor of ten while being identical in the dimension that governs how you work. A 5,000 word white paper, a long dissertation chapter, a full case study: none of those go in as one piece on either plan. You split them, run the parts separately, and paste the results back together, which is exactly the workflow that produces seams. A rewrite that has not seen the paragraph before it cannot keep the transitions consistent, and stitched documents read like stitched documents.
This is not a theoretical complaint. Autocomplete for this brand is full of people asking about it directly: "rewritify no word limit", "rewritify unlimited words", "rewritify 1000 words". The demand behind those searches is a person with a document longer than the box will take, trying to find out which plan solves it. The answer is Unlimited, and on yearly billing Unlimited is not the expensive option, because it costs the same $16 as the tier that will not take the document.
Worth noting for balance: 3,000 words per input is not a bad cap by category standards. Humbot's entry tier stops at 500 words per request, six times tighter, and several tools decline to publish a per-run figure at all, which is worse than a modest one. Rewritify at least tells you the number on the card, in the same place as the price, which is more than most of this field manages.
Under 3,000 words
Blog posts, essays, product pages, most emails. Any tier takes these in one paste. Choose on monthly volume alone.
3,000 to 10,000 words
Dissertation chapters, white papers, long reports. Only Unlimited handles these whole. The other two require splitting.
Recurring long documents
Unlimited yearly at $16, or shop tools that publish a large per-run figure rather than a large pool.
Before you pay
What 80 free words and a three-day refund window really give you
Rewritify's trial is 80 words on signup. Their FAQ puts it plainly: "Our undetectable AI paraphraser allows you to try out our tool with 80 free words." Eighty words is one short paragraph. It is enough to see the register and rhythm of the output, and not remotely enough to judge whether the tool holds a voice across a full piece, which is the only question that matters once you are paying.
That would be a minor complaint if the refund terms were generous, and they are not. The policy requires a request "within three (3) days of making your initial purchase", and separately states that "If you have used over 1,000 words of our service, you will not be eligible for a refund". Both apply at once. On the Basic plan, whose entire monthly allowance is 5,000 words, that means you may evaluate a fifth of one month before your right to a refund lapses. Two long blog posts through the tool and it is gone.
Combine the two and the evaluation path this product offers is 80 words free, then a purchase, then roughly 1,000 words of protected testing inside a 72-hour clock. If you are considering the annual plan, that is a $192 commitment assessed on about four paragraphs of protected use. Buying one month at $49 to test Unlimited properly, then switching to annual, costs $33 more over the year and removes the entire problem.
One more thing belongs in this section because buyers ask about it and the answer is a genuine gap. Rewritify's privacy policy does not state how long submitted text is retained, and does not say whether submitted content is used to train models. It confirms a right to request deletion and gives a support address for that. If your text is client work under an NDA, or unpublished research, an unstated retention period is the sort of thing that ought to decide the purchase before the price does.
The paid field
Entry tiers compared, with the date each vendor's page was read
Prices move in this category. Every row below carries the day we last read it first-party.
| Tool | Entry price | Words per run | Allowance | Read |
|---|---|---|---|---|
| Rewritify | $9/mo billed yearly | 3,000 words | 5,000 words a month | Sep 6, 2026 |
| Humanize AI | $4.99/mo billed yearly | Whole documents on Standard | 25,000 words a month on Standard | Aug 30, 2026 |
| Undetectable.ai | $5/mo billed yearly | Not published | 10,000 words a month | Jul 31, 2026 |
| Humbot | $7.99/mo billed yearly | 500 words | 3,000 basic + 1,000 advanced words | Sep 21, 2026 |
| QuillBot | $8.33/mo billed yearly | Not published for Premium | No word cap published on Premium | Aug 10, 2026 |
| StealthWriter | $20/mo ($200/yr) | 5,000 words | 50 runs a day | Sep 5, 2026 |
| Undetected.ai | from $24/mo billed yearly | 1,500 words | 100,000 words a month | Ours |
Rewritify's entry tier is mid-table on price and weak on what the price buys. At $9 a month billed yearly it sits above Humanize AI and Undetectable.ai, and for that money it gives 5,000 words a month where Undetectable.ai gives 10,000 and Humanize AI gives 25,000. If you are shopping the bottom of this market on allowance alone, Basic is not the plan to pick.
The comparison flips at the top. Very little in this category offers genuinely uncapped words with no per-paste ceiling for $16 a month, and that is what yearly Unlimited is. StealthWriter's much-praised 5,000 word input costs $20 a month and still meters you at 50 runs a day. Judged as a top tier rather than an entry tier, Rewritify is priced well, which is the opposite of the impression you get from reading the first number on the page.
Two figures on their site do not agree, and we would rather say so than tidy it away. The homepage claims support for "over 50 languages" while every pricing card says "30+ languages supported". Both were read on ' . the same day. We use the lower number in the table above because it is the one printed next to the price, on the card you actually buy from.
Buy it, or do not
Who each tier is actually for
Anyone buying annually. Buy Unlimited, never Ultimate. They are the same $16 a month and Unlimited is larger on every published dimension. This is the single most valuable sentence on this page and it takes ten seconds to verify on their own pricing page with the Yearly toggle selected, which is how the page loads by default.
Students with long chapters. Buy Unlimited, or reconsider the product. A dissertation chapter runs well past 3,000 words, and on Basic or Ultimate it has to be split, which is where rewritten text starts to read as though different people wrote consecutive sections. If your budget is genuinely $9 a month, you will get more usable work out of a tool that takes the whole chapter at once.
Bloggers and marketers under 3,000 words a piece. Basic is workable but not good value. Five thousand words a month is two or three posts, and rewriting is iterative, so a single post you run three times can consume most of a week's allowance. Price a tool on the words you will burn re-running drafts, not on the words you will publish, and the entry tiers elsewhere in the table look better.
Anyone who needs this in a pipeline. Do not buy any tier. There is no API and no browser extension, and no tier adds either. The entire site is six functional pages and some legal text, with no developer documentation anywhere on it. If you want rewriting to happen from your own code or a scheduled job, an AI humanizer with a documented API is the category to shop in instead.
Anyone still deciding between vendors. Do not buy from a table, including this one. Published caps tell you what a tool is allowed to do, not what its output sounds like, and the whole point of a humanizer is the second thing. Run one real paragraph of your own writing through two or three candidates and read the results side by side. Eighty free words is enough to do that here.
Frequently asked
Rewritify questions people actually search
How much does Rewritify cost?
Rewritify costs $14, $24 or $49 a month, or $9, $16 and $16 a month billed yearly, all in USD. Basic gives 5,000 words a month, Ultimate 50,000 and Unlimited has no monthly cap. Every figure here was read on rewritify.ai/pricing on September 6, 2026 through three separate channels.
Is Rewritify free?
No, it is a paid subscription with a sample rather than a free tier. Rewritify gives you 80 words once you create an account, which their own FAQ describes as a way to try the tool. Eighty words is roughly one short paragraph, so treat it as a demo of the output style rather than as a usable free plan.
Does Rewritify have a word limit?
Yes, two of them, and they are separate. There is a monthly allowance of 5,000 words on Basic and 50,000 on Ultimate, and there is a per-input cap of 3,000 words on both of those tiers. Only the Unlimited plan removes both. A 4,000 word essay cannot go in as one paste on Basic or Ultimate.
Which Rewritify plan is best value?
Unlimited on yearly billing, and it is not close. Yearly Unlimited and yearly Ultimate are both $16 a month, but Unlimited has no monthly word cap and no per-input cap, while Ultimate stops at 50,000 words and 3,000 per paste. At the same price the middle tier gives you strictly less of everything.
Can you get a refund from Rewritify?
Only inside a narrow window. Their refund policy requires the request within three days of the initial purchase, and separately says you are not eligible once you have used over 1,000 words. Both conditions apply, so on the 5,000 word Basic plan you can test a fifth of one month before the refund right lapses.
Is Rewritify legit?
It is a real product that has been running since 2024, takes card payments through the usual processors and publishes terms, privacy and refund policies. What it does not publish is a data retention period or a statement about whether submitted text is used for training, so judge it on the price and the caps rather than on data handling.
Does Rewritify have an API?
No, and there is no browser extension either. The whole site consists of the humanizer, an AI detector page, a bypass page, pricing, sign-in and sign-up, three legal pages and fifteen translated pricing pages. There is no developer documentation anywhere on it, so anything scripted or scheduled is out of scope.
Is Rewritify worth it compared to cheaper humanizers?
At $16 a month yearly for the Unlimited plan it is competitive, because uncapped input is rare at that price. At $9 a month for Basic it is poor value, since 5,000 words a month with a 3,000 word paste ceiling is beaten on both counts by entry tiers around $5 elsewhere. Buy the top tier here or buy elsewhere.
