This QuillBot review covers a writing suite built around a paraphraser, with a grammar checker, summarizer, citation generator and plagiarism checker. Premium, for example, costs $8.33 a month on yearly billing.
Its free plan paraphrases up to 125 words at a time in two modes. QuillBot also lets account holders opt out of training, though storing inputs is on by default.
QuillBot Review: Is It Worth It in 2026?
For students and writers who paraphrase and check text often, yes, on yearly billing. Monthly Premium, however, costs $19.95.
For drafting from scratch, a general assistant fits better. Our list of the best AI for students compares study tools.
What QuillBot Does
First, the paraphraser rewrites text in modes such as Standard, Fluency, Formal and Creative. It also checks grammar, summarizes long text, formats citations and, on Premium, checks for plagiarism.
QuillBot also runs on the web, in browsers, on desktop and mobile, and in Word. Our guide to using AI for editing shows where paraphrasers fit.
What QuillBot Costs
In addition, QuillBot sells one individual paid plan and a Team plan, as trackers read its pricing page in July and August 2026.
| Plan | Price | What it includes |
|---|---|---|
| Free | $0 | 125-word paraphrasing; 2 modes; limited summarizer |
| Premium | $19.95/mo, or $99.95 a year ($8.33/mo) | Unlimited paraphrasing; 9 modes; plagiarism checks |
| Team | By quote | Central billing; no training on inputs |
Premium’s plagiarism checker covers 25,000 words a month, one tracker reports. Yearly billing, moreover, saves 58% against monthly, as our guide to annual vs monthly AI subscriptions explains.
Accuracy and Academic Use
We found no independent test of QuillBot’s paraphrasing quality. Paraphrases, therefore, can shift meaning, so check them against the original, as our guide to fact-checking AI output explains.
QuillBot also offers a Humanizer. Using any paraphraser to disguise AI-written or copied work, however, can break school and publisher rules, so follow your institution’s policy, as our guide to avoiding overuse of AI in writing discusses.
Your Data
QuillBot’s trust center says account holders can opt out of letting it use text inputs to train its models, and that it does not train on Team plan inputs. Storing inputs, however, is on by default.
It also says it does not let third-party providers train on your data, for example. Our guide to which AI tools train on your data compares other tools.

General assistants such as ChatGPT, however, also paraphrase, as our guide to ChatGPT for writing covers.
