We would rather put this at the top than bury it. QuillBot blocks automated requests to its pricing page, which means we โ and every other site publishing QuillBot prices โ cannot simply read the official numbers. What we can do is cross-check the third-party figures, show you where they conflict, and point you at the only authoritative source: QuillBot's own checkout.
Treat everything on this page as a September 2026 third-party snapshot, not an official quote.
The free tier is the part of QuillBot that most people will actually use, so it is worth being precise about the ceiling:
| Free plan limit | The number | What it means in practice |
|---|---|---|
| Paraphrase length | 125 words per pass | Roughly one to two paragraphs at a time |
| Paraphrasing modes | 2 modes (Standard and Fluency) | The academic and creative-style modes sit behind Premium |
| Summarizer | 1,200 words | A short article or a section of a paper |
| Grammar checking | Basic | Enough for typos, not for full-sentence rewriting |
| Price | $0, no credit card | This is the real trial โ see below |
One structural detail matters more than any single number: the free plan's limit is per pass, not per month. We could not verify a monthly character allowance of the kind Rytr uses, and as far as the published limits go, there isn't one โ you can run as many 125-word passes as you like. That makes free unusually generous for someone who fixes a couple of sentences a day, and close to useless for someone who wants to rewrite a 2,000-word draft in one sitting.
It also tells you what the product is for. Rytr gives away 10,000 characters a month; ChatGPT and Claude give away a general-purpose model. QuillBot gives away 125 words at a time because its business is the sentence you are stuck on โ the small, recurring moment where $8.33 a month feels reasonable.
125 words is roughly eight to ten English sentences, or a little under half a page double-spaced. A typical paragraph runs 100โ150 words, so one pass covers about one paragraph. That is fine until you apply it to a real document:
| The job | Length | Passes on the free plan |
|---|---|---|
| A sentence that reads awkwardly | 25 words | 1 |
| A paragraph you want rephrased | 120 words | 1 |
| A short email | 200 words | 2 |
| A 1,200-word essay | 1,200 words | ~10 |
| A 2,000-word blog post | 2,000 words | ~16 |
| A 5,000-word thesis chapter | 5,000 words | ~40 |
The passes themselves are free; the cost is the chunking. Ten cut-and-paste round trips through a web editor is the friction that pushes heavy users to Premium, and it is the honest argument for paying โ not output quality, which we cannot score, but time. See our paraphrasing tools roundup for alternatives that do not meter by the paragraph, and how to paraphrase with AI for the workflow.
QuillBot sells Premium on three billing periods, and the spread between them is the largest single fact on this page:
| Billing period | Price as listed | Effective monthly | Cost over 12 months |
|---|---|---|---|
| Monthly | $19.95/mo | $19.95 | $239.40 |
| Quarterly | $39.95 per quarter | ~$13.31 | $159.80 |
| Annual | $99.95/year | ~$8.33 | $99.95 |
Annual vs monthly: $99.95 รท $19.95 = 5 months. Stay past month five and annual is already cheaper โ it saves $139.45 across the year, about 58% off the monthly rate. Quarterly vs monthly: $39.95 รท $19.95 = 2 months, so quarterly wins from month three. Quarterly vs annual: $99.95 รท $39.95 = 2.5 quarters, roughly 7.5 months.
The quarterly plan is the honest middle step and gets less attention than it deserves. At about $13.31/mo it is roughly a third off the monthly rate, and it only commits you to three months โ about how long it takes to learn whether your rewriting habit is permanent. Still using QuillBot after two quarters? Move to annual.
One comparison worth making explicitly, because the two tools get confused: $8.33/mo for a rewriter is more than Rytr Unlimited at $7.50/mo for a full generator (billed annually at $90/year; $9/mo monthly). If you need text produced rather than text reworded, the rewriter is the more expensive tool. The full breakdown is in our Rytr pricing guide.
We have to be straight about the numbers circulating, because a buyer comparing three tabs will otherwise assume they are all reading the same thing. In September 2026, third-party listings for QuillBot Premium included:
Those sets do not agree, and we could not verify which is current, because QuillBot's own pricing page is not readable by automated tools. The $4.17/mo figure in particular may be an expired promotion, a regional price, or simply wrong. If you see a QuillBot price quoted without a billing period attached, treat it as unverified. The same applies to any page that lists a single "QuillBot Premium price" without saying whether it is monthly, quarterly or annual โ including older versions of this one.
One practical difference to know before you type in a card number: QuillBot Premium does not come with a free trial. What it offers is a 3-day money-back guarantee. You pay, then you have three days to claim a refund.
Three days is a short window โ shorter than a weekend in some weeks. If you are testing whether Premium suits your workflow, do it deliberately: buy at the start of a working week, run one real rewriting job inside those three days, and decide on evidence rather than a first impression. Buying on a Friday and forgetting is how a refund window expires unused.
Practical consequence: the free plan is the real trial, and the only risk-free way to find out whether 125 words per pass covers your work. Start there. If free is not enough after a fortnight, the decision is between the three billing periods above, not between buying and not buying.
You rewrite a sentence or two a week, usually because a line reads awkwardly. One 125-word pass covers that exactly, and Standard and Fluency are enough to get unstuck. Paying $19.95/mo for this is a waste, and even $8.33/mo is hard to justify at four passes a month.
You rewrite every working day: non-native English speakers polishing their own prose, students working through drafts, marketers reusing copy across channels. Here the pass limit is not the issue โ the chunking friction is, and Premium removes it. At $8.33/mo for unlimited passes this is a fair price for the profile QuillBot is built around. Whether the tool's output is any good is a separate question, and one we cover in our QuillBot review and in is QuillBot Premium worth it.
If what you actually want is text produced from a prompt rather than your own sentences reworded, a rewriter is the wrong category. QuillBot Premium's annual rate is close to what a full AI writer costs, and generators start from nothing rather than from your draft. See QuillBot alternatives for what that swap looks like.
QuillBot is not one of the tools in our 30-day benchmark, so we do not publish a hands-on score for it. Everything above is about price, plan structure and limits. Any quality comparison you read on this site involving QuillBot is based on public information rather than our own testing โ see how we test for the tools that are in scope.
The most common comparison is QuillBot against Grammarly, and they are not the same job: Grammarly corrects grammar, QuillBot rewrites. On price, one thing is worth flagging in 2026 โ Grammarly has renamed its paid tier. "Premium" is now "Pro." The old name still appears on many pages, including some of our own older URLs, but the current tier name is Pro.
| Tool | Free tier | Paid tier | Billing period |
|---|---|---|---|
| QuillBot | 125 words per paraphrase pass, 2 modes, 1,200-word summarizer | Premium: $19.95/mo, or $39.95/quarter (~$13.31/mo), or $99.95/year (~$8.33/mo) | Monthly, quarterly or annual |
| Grammarly (paid tier renamed Pro) | Basic grammar and spelling, 100 AI prompts per month | Pro: $30/mo monthly, or $12/mo billed annually ($144/year charged once) | Monthly or annual |
| Grammarly Business | None | $15 per user/mo | Annual |
Read across: at the annual rates, Grammarly Pro ($12/mo) costs more than QuillBot Premium ($8.33/mo), and at the monthly rates Grammarly Pro ($30/mo) costs more than QuillBot Premium ($19.95/mo). QuillBot is the cheaper subscription on both billing periods. But cheaper only matters if rewriting is the job you need done โ if your problem is comma splices, tone and correctness, then the cheaper tool is the wrong tool regardless of what it costs. Our Grammarly vs QuillBot comparison works through the choice, and Grammarly pricing covers the rename and the current tier structure.
QuillBot Premium's annual rate only makes sense in context, so here is the same money against the rest of the category. Every figure carries its billing period; prices re-checked September 2026.
| Tool | Cheapest paid tier | Billing period | What it is |
|---|---|---|---|
| ChatGPT Go | $5/mo | Monthly | General-purpose chat, between Free and Plus |
| Rytr Unlimited | $7.50/mo | Annual, $90 prepaid ($9/mo monthly) | Generator, short-form |
| QuillBot Premium | ~$8.33/mo | Annual, $99.95 prepaid | Rewriter |
| Grammarly Pro | $12/mo | Annual, $144 prepaid ($30/mo monthly) | Grammar and tone editor |
| Claude Pro | $20/mo (about $17/mo annually, $200/year) | Monthly or annual | Generator, long-form |
| ChatGPT Plus | $20/mo | Monthly | General-purpose chat |
| Copy.ai Chat | $24/mo | Annual ($29/mo monthly) | Go-to-market workflows |
| Jasper Creator | $39/mo | Annual ($49/mo monthly) | Generator, brand voice at volume |
| Writesonic Starter | $79/mo | Annual (about $99/mo monthly) | GEO and AI-visibility platform |
At $8.33/mo, QuillBot Premium annual sits below every full-featured generator on this list. It is not an expensive subscription; it is a narrow one. The question is not "is it cheap" but "is rewriting the work I actually have" โ and if the answer is no, the cheapest tool on this page is still the wrong purchase. Our real monthly cost breakdown adds the hidden cost no price table shows: editing time.
QuillBot-rewritten text can be flagged by AI detectors, especially with aggressive paraphrasing, and schools and editors do run detection tools on submitted work. Use QuillBot to improve writing you did yourself โ not to disguise authorship or sidestep an integrity policy. Our AI writing tools vs AI detectors explainer covers what those tools measure, and AI writing tools for students covers staying on the right side of the line.
One piece of standing advice: always read a paraphrase back for meaning. A rewriter is optimizing for different wording, not for preserving your technical accuracy, so the sentence that comes out can be smoother and less true than the one that went in. That is true of every paraphraser, including the one we recommend.
125 words per pass, two modes, no credit card. If it covers your work, you never need to pay.
Try QuillBot Free โYes. The free plan paraphrases up to 125 words per pass in two modes, summarizes up to 1,200 words, and includes basic grammar checking. No credit card is required.
Premium is $19.95/mo billed monthly. Billed quarterly it is $39.95 per quarter (about $13.31/mo), and billed annually it is $99.95/year, or about $8.33/mo. The annual rate pays for itself after five months.
QuillBot blocks automated checks of its pricing page, so third-party sites publish figures that conflict, including a $4.17/mo annual figure we could not verify. We could not confirm official pricing directly as of September 2026, so verify any price on QuillBot's own checkout before buying.
No. QuillBot Premium offers a 3-day money-back guarantee rather than a free trial, so you pay first and claim a refund inside three days. The free plan is the real trial.
Only at the annual rate, and only if you rewrite daily. At $8.33/mo for unlimited paraphrasing it is fair value for a rewriter; at $19.95 billed monthly it is steep.
They do different jobs. QuillBot rewrites sentences; Grammarly corrects grammar. On price, QuillBot Premium annual ($8.33/mo) undercuts Grammarly Pro annual ($12/mo), but that only matters if rewriting is the job you need done.
