Research offices, principal investigators, and graduate students evaluating a paraphrasing tool like QuillBot are usually facing two separate questions at once: how should this actually be paid for — personal expense, a grant line item, or a department-negotiated license — and does using it on a manuscript, thesis chapter, or grant narrative trigger a disclosure obligation under a journal’s or funder’s AI-use policy. Both questions matter more than the sticker price, and most QuillBot review pages skip both. This guide covers QuillBot’s actual current pricing and plan tiers in full, then works through the procurement and research-integrity considerations that actually decide whether it belongs on a research budget at all.
How Much Does QuillBot Cost?
As of August 2026, verified directly on QuillBot’s own pricing page, QuillBot Premium starts at $8.33/month when billed annually (marketed on the vendor’s site as a 58% discount off the standard monthly rate). QuillBot also offers a free plan with no payment required, though it’s capped tightly enough that most people who paraphrase or write regularly outgrow it quickly. QuillBot’s site does not publish separate monthly or six-month billing prices on its main pricing page at the time of writing — if you want a shorter commitment than annual billing, check the live checkout flow for current monthly/semi-annual rates before you buy, since QuillBot (like most SaaS tools) changes pricing periodically.
There’s also a Team plan for labs, departments, or research groups buying multiple seats, priced on request rather than listed publicly — QuillBot notes volume discounts for groups of 5 or more members, which matters if you’re trying to get a whole lab covered under one purchase order rather than expensing individual subscriptions.
QuillBot Free Plan vs Premium — What You Actually Get
The free plan is a genuine trial of the product, not a fully usable standalone tool for regular research writing:
- Free: paraphrasing capped at 125 words per use, only 2 of QuillBot’s paraphrasing modes (Standard and Fluency), basic grammar fixes, limited AI-detector access, and a 1,200-word summarizer.
- Premium: removes the 125-word paraphrasing cap, unlocks all 9 paraphrasing modes (including Academic mode, built specifically for scholarly register), adds full AI-detector access, a plagiarism checker covering 25,000 words/month, citation generation in APA/MLA/Chicago, and multi-device access across up to 10 devices.
For a one-off use — cleaning up a single abstract or cover letter — the free tier may genuinely be enough. For anyone paraphrasing regularly across a thesis, multiple manuscripts, or grant narratives, the 125-word cap and 2-mode limit make the free plan impractical fast, which is the actual pricing decision most researchers are facing.

QuillBot Premium: What’s In the Paid Plan
QuillBot Premium is the single paid tier that unlocks the full product — there is no mid-tier “Plus” plan sitting between Free and Premium. Verified via QuillBot’s own site (August 2026), Premium includes:
- All 9 paraphrasing modes (Standard, Fluency, Formal, Simple, Creative, Academic, Expand, Shorten, Humanize) plus unlimited custom-mode creation
- No word cap on paraphrasing (free is capped at 125 words per use)
- Advanced grammar recommendations and tone insights, with grammar correction across 6 languages
- Full AI Detector access and a plagiarism checker (25,000 words/month)
- Citation generation in APA, MLA, and Chicago formats
- Custom summaries up to 6,000 words (versus 1,200 words on the free plan)
- Faster processing and 100 MB of document storage
- Browser extensions and apps across Chrome, Edge, Safari, Word, Windows, macOS, iOS, and Android, usable on up to 10 devices
QuillBot’s site does not display a standard, published refund or money-back guarantee on its pricing page — if that matters for your purchase, confirm current terms in the checkout flow or with QuillBot support before you pay, rather than assuming a policy that may not exist.
Research Integrity and Disclosure: Does Using QuillBot Require AI Disclosure?
Paraphrasing tools sit inside a broader category — generative and AI-assisted writing tools — that most journals, funders, and research-integrity offices now have an explicit disclosure policy for, entirely separate from the budget question above. COPE’s (Committee on Publication Ethics) position statement on authorship and AI tools, published February 2023, is the reference point most journal policies are still built on: AI tools cannot be listed as an author, since they cannot take responsibility for the work or manage conflicts of interest or licensing, and authors who use generative AI in preparing a manuscript — including for paraphrasing or rewriting existing text — are expected to disclose which tool was used and how, typically in the Methods section or an equivalent statement. Some journals (see, for example, ICMJE’s generative-AI guidance) build their own author instructions on top of this baseline. QuillBot’s paraphrasing modes, including its Academic mode, fall inside “AI-assisted rewriting” for this purpose, even though the tool is rewording a researcher’s own material rather than generating new content from a prompt.
Practically, this means two things worth building into how a lab or department uses and pays for the tool. First, check the specific disclosure requirement of the journal, thesis committee, or funder before submission — policies vary in how much detail they want and where the statement goes, and a generative-AI disclosure statement that satisfies one venue may not satisfy another, so COPE’s guidance is a floor, not a ceiling. Second, if a department is deciding whether to fund a group license for a paraphrasing tool, loop in the research-integrity or scholarly-communications office alongside procurement, not procurement alone — a shared institutional license is also a natural moment to standardize disclosure language and usage guidance across a department, rather than leaving each author to interpret journal policy independently. Funder and university AI-use policies are still moving targets; treat this section as a starting point for the conversation, not a substitute for checking current guidance from the specific journal or funder involved.
Is QuillBot Worth Expensing to Your Department or Lab Budget?
This is where the pricing decision actually gets interesting for research staff, and it’s the part most QuillBot review pages skip. A few things worth weighing before you either pay out of pocket or submit a reimbursement request:
- Annual billing is cheaper per month but a bigger single charge. $8.33/month sounds trivial, but billed annually that’s roughly $100 charged at once. If your department has a small-purchase or per-item reimbursement cap, check whether an annual software charge clears it before you buy — a monthly or shorter billing cycle (if available at checkout) may be easier to expense even though the per-month rate is higher.
- Individual subscriptions are harder to procure centrally than most people expect. Research offices are generally set up to purchase site licenses or institutional software (e.g., a campus-wide Grammarly or EndNote license), not to reimburse a $100/year personal SaaS subscription — check whether your institution already has a bulk license for a writing tool before assuming you need to buy your own.
- Frame the request around output, not the tool. A reimbursement or grant-budget request is more likely to succeed framed as “editing/proofreading support for manuscript preparation” (a legitimate, common research expense category) than as a specific software brand name — check your funder’s and institution’s allowable-cost guidance for what counts as a reimbursable research or professional-development expense.
- If you’re a student rather than staff or faculty, department reimbursement is usually not an option at all, and the $8.33/month personal cost is the realistic comparison point against a library-provided or campus-licensed alternative, if one exists.
How QuillBot’s Pricing Compares
QuillBot Premium’s $8.33/month annual rate runs lower than Grammarly Pro’s $12/month, but the two tools solve different problems — QuillBot is built around paraphrasing with a basic grammar checker attached, while Grammarly is built around continuous grammar/clarity/tone checking with a basic rewrite feature attached.

Who Should Skip QuillBot Premium
QuillBot Premium is not the right purchase for everyone, and it’s worth saying plainly where it isn’t:
- If your main need is proofreading, not paraphrasing — catching grammar errors, awkward phrasing, and tone issues as you type across a full manuscript — a grammar-focused tool like Grammarly is the better fit, and its free tier alone may cover core grammar/spelling checking without a paid plan at all.
- If you only need occasional light paraphrasing — a single sentence or short passage now and then — the free plan’s 125-word cap may genuinely be enough, and paying $100/year for Premium would be needless expense.
- If your institution already provides a licensed writing-assistance tool campus-wide, check that first; paying for a personal QuillBot subscription on top of an existing institutional license is a real, avoidable cost most researchers don’t think to check for before buying.
Where QuillBot Premium does earn its cost: controlled paraphrasing with an Academic mode built for scholarly register, a word-similarity control most competitors don’t offer, and multilingual support for researchers drafting in a second language — for that specific job, it’s genuinely purpose-built in a way a general grammar checker is not.
Frequently Asked Questions
How much does QuillBot cost?
QuillBot Premium starts at $8.33/month when billed annually (verified on QuillBot’s own site, August 2026) — roughly $100 charged once per year. QuillBot also offers a free plan with no cost, but it’s capped at 125 words per paraphrase and only 2 of the 9 available modes. QuillBot’s pricing page does not publish separate monthly or six-month rates, so check the live checkout for current short-term billing options if annual billing doesn’t suit your budget.
What does QuillBot Premium include?
All 9 paraphrasing modes with no word cap, full AI Detector access, a 25,000-word/month plagiarism checker, citation generation (APA/MLA/Chicago), 6,000-word custom summaries, advanced grammar and tone insights, and multi-device access across up to 10 devices. See the full breakdown above.
Is there a QuillBot student discount?
QuillBot’s pricing page does not list a published student discount as of August 2026 — if one exists it isn’t advertised on the main pricing page, so don’t assume a discount is available without checking directly at checkout.
Can I expense QuillBot Premium through my lab or department?
It depends entirely on your institution’s procurement and allowable-cost policies — there’s no universal answer. Check whether your department has a small-purchase reimbursement process, whether your funder’s budget guidance treats editing/writing-support tools as an allowable cost, and whether your institution already has a bulk-licensed writing tool before assuming you need to buy an individual subscription. See the budgeting section above for what’s worth checking before you submit a request.
Does using QuillBot on a manuscript require AI-use disclosure?
Possibly, depending on the journal, funder, or thesis committee. COPE’s position statement on authorship and AI tools treats AI-assisted rewriting — which covers QuillBot’s paraphrasing modes — as something that should be disclosed, typically in the Methods section or an equivalent statement, even though the tool cannot itself be listed as an author. Individual publishers layer their own requirements on top of that baseline, so check the specific venue’s current author instructions rather than assuming one disclosure format covers every submission. See the research-integrity section above for more.
Does QuillBot offer a free trial of Premium, or refunds?
QuillBot’s free plan functions as an ongoing (if limited) trial of the core paraphrasing tool rather than a time-boxed Premium trial. QuillBot’s pricing page does not display a published refund or money-back guarantee — confirm current terms directly with QuillBot before purchasing if that matters to your decision.
