QuillBot is an AI paraphrasing and writing tool that suits students, bloggers, freelance writers and anyone who writes in English as a second language and wants sentences reworded quickly. It has a free plan, Premium costs $8.33 a month billed yearly ($99.95, checked 9 November 2026), and I score it 7.5 out of 10. The things worth knowing before you pay are less about the paraphraser and more about the paperwork: a monthly price that’s more than double the yearly rate, a three-day refund window that skips renewals, and a training setting that is switched on unless you find it.
Disclosure: I don’t earn a commission from QuillBot. It runs an affiliate program through PartnerStack, but I haven’t joined it, and every QuillBot link on this page is a plain link.

Five numbers before you sign up
| Measure | My reading |
|---|---|
| Time | Paste text and pick a mode; there is nothing to set up, and extensions cover Chrome, Word and Google Docs |
| Cost | Free plan; Premium $99.95 a year ($8.33 a month); trackers list $19.95 monthly |
| Output | Reworded sentences, grammar fixes, summaries, citations, AI-detection scores and a plagiarism check of 25,000 words a month |
| Real earning path | Rewriting supplier product descriptions into original copy for small online shops |
| Overall | 7.5/10 |
Buy it, or pass?
Buy Premium if you reword, summarise or tidy text most weeks and will keep it for six months or more. At $99.95 a year it costs less than most grammar tools, and the paraphraser has no word cap.
Pass if you only need a quick rewrite now and then (the free plan covers that), if you handle confidential client text and won’t change the privacy setting, or if you hope it will disguise copied or AI-written work.
How I checked QuillBot, and the four scores
I haven’t used QuillBot for paid work, so this is a research review rather than a hands-on test. On 9 November 2026 I read QuillBot’s Premium page, refund help article, data privacy page, privacy update notes, affiliate page and About page, plus Trustpilot, G2 and Capterra, four pricing trackers, Turnitin coverage and the plan pages of Wordtune, ProWritingAid and Grammarly. QuillBot’s Terms of Service page returned an error each time I tried it, so I don’t quote it. The cost figures below are my own arithmetic.
| Area | Score | Reason |
|---|---|---|
| Ease of use | 8.5/10 | Capterra users rate ease of use 4.6 out of 5, and the editor works inside Word, Docs and Chrome |
| Output quality | 7/10 | Rewrites usually keep the meaning, but G2 and Capterra users report drift in Creative mode and odd synonyms |
| Value for money | 8/10 | $99.95 a year is low for unlimited paraphrasing; the monthly price is steep by comparison |
| Trust and support | 6.5/10 | Fast replies to complaints, but a short refund window, renewal complaints and training switched on by default |
| Overall | 7.5/10 | Average of the four |
If a price or policy here has changed, send me a note through the contact page and I’ll fix it.
Is QuillBot free, and where does the free plan stop?
Yes, and the free plan is generous for occasional use. It paraphrases up to 125 words per run in two modes (Standard and Fluency), fixes basic grammar errors, summarises up to 1,200 words, gives limited AI-detector access and three Humanizer uses, all without a card. There is no plagiarism checker on the free plan, and the other seven paraphrasing modes and custom modes sit behind Premium.
How much does QuillBot Premium cost in November 2026?
$99.95 a year, or $8.33 a month, is the price QuillBot’s own Premium page showed me on 9 November 2026. The page showed no monthly toggle; it also displayed an unexplained $5.00 figure next to the $8.33, which may be a promotion, so look at checkout before you assume either.
| Billing | Charged | Per month | Where the figure comes from |
|---|---|---|---|
| Free | $0 | $0 | QuillBot Premium page |
| Yearly | $99.95 a year | $8.33 | QuillBot Premium page ($8.33); trackers for the $99.95 total |
| Every three months | $39.95 | $13.32 | RewritePal (checked 27 September) and Toolsurf (October) |
| Monthly | $19.95 | $19.95 | RewritePal, Toolsurf, Hackceleration and CostBench (checked 4 November) |
| Team Plan | Quote | Quote | Discount from five seats; contact sales |
Premium adds unlimited paraphrasing in nine modes plus custom modes, advanced grammar suggestions in six languages, summaries up to 6,000 words, unlimited Humanizer and AI-detector use, citations, paraphrase history and 25,000 words of plagiarism checks a month.
When does the yearly plan beat paying monthly?
After five months. Five monthly payments come to $99.75, twenty cents short of a full year, so anyone who expects to keep QuillBot for six months or more saves by paying upfront.
| Plan | Cost over 12 months | Cost per 1,000 words of plagiarism checks* |
|---|---|---|
| Monthly ($19.95) | $239.40 | $0.80 |
| Three-monthly ($39.95) | $159.80 | $0.53 |
| Yearly ($99.95) | $99.95 | $0.33 |
The yearly plan works out 58% cheaper than twelve monthly payments. The cheapest way to test it runs the opposite way to how most people buy: start on the free plan, buy one month if the free limits annoy you, then switch to yearly once you know you’ll stay.
What QuillBot does beyond paraphrasing
Quite a lot for one subscription: a grammar checker, Summarizer, AI Detector, Humanizer, plagiarism checker, citation generator, translator, AI chat and QuillBot Flow, a writing space with 100 MB of storage on Premium.
QuillBot started in 2017 as a dorm-room project by Anil Jason, Rohan Gupta and David Silin, built to help English learners; by 2019 it had an office in Chicago. Its About page now claims 56 million monthly active writers and 243 staff. It is one of the brands of Learneo, alongside Course Hero, CliffsNotes, LitCharts, Scribbr and Symbolab, and Learneo’s legal page lists QuillBot as a service under Learneo’s terms.
Does QuillBot train on what you type?
Yes, unless you turn it off or pay for the Team Plan. QuillBot’s data privacy page says it uses inputs and usage data to provide the service and “for training to improve its services generally”. Since a privacy update tied to extension version 4.37.0, storage of extension text is on by default for everyone, with two opt-outs: one for storage (all users) and one for training (account holders only), found under View All Settings, then Data and Privacy.
Anyone who said yes to the old consent prompt was moved to the training opt-in automatically, while Team Plan inputs are never used for training. For client drafts under NDA, that setting matters more than any feature. I found no SOC 2 or ISO mention on the page. I’m not a lawyer, so check your own client contracts.
Is using QuillBot cheating, and can Turnitin spot it?
It depends entirely on whose words go in. Rewording your own draft for clarity is editing; feeding in a source or an AI answer and handing in the result as your own work is what universities treat as plagiarism or misconduct.
On detection, Turnitin announced “AI bypasser detection” on 27 August 2025 to flag text altered by humanizer tools, adding to an anti-paraphrasing feature from July 2024. Plagiarism Today noted that Turnitin’s claimed false positive rate of under 1% still needs independent testing, and G2 users call QuillBot’s own AI Detector inconsistent.
Can you get your money back from QuillBot?
Once, and only quickly. QuillBot’s help centre says new Premium buyers may get a refund within 3 days of purchase in most countries, or 14 days in Europe. Each user gets one refund, the purchase must be made on QuillBot.com, renewals aren’t refundable unless the law requires it, and Team Plans and app-store purchases are excluded.
That renewal rule lines up with the complaints. Several one-star Trustpilot reviews from 9 and 10 October 2026 describe charges after a short plan renewed, and one says a refund was refused despite a quick request. You can pause a subscription from the Account page instead of cancelling.
What 14,465 Trustpilot reviewers and G2 users report
Mostly praise, with a renewal problem in the minority. On 9 November 2026 Trustpilot showed QuillBot at 4.8 out of 5 from 14,465 reviews, 8,607 of them in the past year, split 87% five-star and 3% one-star, and QuillBot had replied to 99% of negative reviews, usually within a week.
The business-software sites are smaller and cooler. G2 shows 4.4 out of 5 from 80 reviews, with ease of use and time saved as the main pros and meaning drift, mechanical wording and inconsistent AI detection as the cons. Capterra shows 4.5 from 157 reviews (ease of use 4.6, customer service 4.2), and a few complaints about slow support and refunds.

Is Wordtune, ProWritingAid or Grammarly better value?
For pure rewording on a budget, Wordtune Unlimited comes closest on price; for deep editing of long documents, ProWritingAid; for grammar and tone, Grammarly. QuillBot stays the broadest bundle for the money.
| Tool | Price (checked 9 November 2026) | Free plan | Best for |
|---|---|---|---|
| QuillBot Premium | $99.95/yr ($8.33/mo); $19.95 monthly per trackers | Yes, 125 words per paraphrase | Rewording, summaries, plagiarism checks |
| Wordtune | Advanced $6.99/mo or $4.89/mo yearly (30 rewrites a day); Unlimited $9.99 or $6.99/mo yearly | Yes, 10 rewrites a day | Sentence rewrites inside the browser |
| ProWritingAid | Premium $30/mo or $120/yr; lifetime $399 | Yes, 500 words per check | Long-form and fiction editing |
| Grammarly | Pro $12 (plans page, billing period not shown) | Yes, 100 AI prompts a month | Grammar, tone and AI drafting |
My Grammarly review covers its AI caps. For search-led rewriting, the Surfer SEO review and Semrush review cover the research side, and newsletter writers may want the beehiiv review.
Where I land on QuillBot
QuillBot Premium is good value on yearly billing and poor value month to month, and its free plan is enough for many people. The paraphraser does what it claims, as long as you read every rewrite before using it. My score loses points on trust: a short refund window with renewals excluded, and a training default most users won’t notice. Turn that setting off on day one, and set a reminder a week before renewal.
Can QuillBot pay for itself?
It can, through small writing jobs rather than anything passive. My earning guide covers rewriting supplier product descriptions for small online shops, with real Fiverr prices, a worked month and the Google and Fiverr rules that sink careless rewriters.
QuillBot questions people ask
Is QuillBot free?
Yes, QuillBot has a free plan with no card required. It paraphrases up to 125 words at a time in two modes, summarises up to 1,200 words, checks basic grammar and gives you three Humanizer uses, but it has no plagiarism checker.
How much is QuillBot Premium per month?
$8.33 a month if you pay $99.95 for a year, which is the only price QuillBot’s own page showed on 9 November 2026. Pricing trackers list $19.95 for a single month and $39.95 for three months.
Is using QuillBot cheating?
Not by itself, but it can be. Paraphrasing your own draft is ordinary editing, while running someone else’s words or an AI answer through it to pass it off as yours breaks most university rules, so check your course policy first.
Can Turnitin detect QuillBot?
Possibly, and you shouldn’t bet a grade on it not doing so. Turnitin added a feature in August 2025 aimed at text altered by AI humanizer tools, on top of an earlier anti-paraphrasing feature, though independent accuracy figures are thin.
Does QuillBot use my writing to train its AI?
Yes, by default, unless you opt out or use the Team Plan. QuillBot’s data page says inputs are used for training, account holders can switch that off in the extension settings, and Team Plan text is never used for training.
Can I get a refund from QuillBot?
Yes, once, if you are new and ask within 3 days of paying (14 days in Europe). Renewals, App Store purchases and Team Plans are not covered, and each person gets only one refund.
Is QuillBot better than Grammarly?
For rewording, yes; for full grammar and tone checking, Grammarly is the stronger pick. QuillBot Premium is also cheaper on yearly billing, $99.95 a year against Grammarly Pro’s listed $12 (its plans page didn’t show the billing period).
