Pricing

Pricing model: Freemium
Paid options from: $19.99/mo
Billing: Monthly

The website refused automated fetches (HTTP 403), so prices come from the vendor's US App Store listing: Premium at $19.99 a month, $79.99 for six months or $99.99 a year; the free tier includes the grammar checker, two paraphraser modes, translator and AI detector.

Overview

About QuillBot

QuillBot rewrites text in selectable paraphrasing modes, checks grammar, summarises documents, translates, builds citations and flags AI-written passages, with the free tier covering the grammar checker, two paraphrase modes, the translator and the AI detector. Premium unlocks the remaining modes, longer inputs, tone and clarity suggestions and the plagiarism checker across the web app, a Chrome extension, a Windows app, a macOS and Safari app and iOS and Android keyboards. It is part of Learneo, the education group that also owns Course Hero, Scribbr and LanguageTool, and it is used mostly by students and non-native writers polishing essays and email.

Editorial verdict

Pros & cons of QuillBot

low confidence

QuillBot remains the fastest way to reword a paragraph you have already written, and the free tier is enough for occasional use; Premium at roughly $8 to $20 a month depending on term buys the extra modes, longer inputs and the plagiarism checker that students actually want. Against a general chatbot it wins on speed and a purpose-built interface, not on writing quality, and against Grammarly it is cheaper but narrower.

Pros

Free tier includes grammar checking, two paraphrase modes, translation and AI detection
Extensions and apps for Chrome, Windows, macOS, Safari, iOS and Android keep it inside the writing surface
Paraphrase modes and a synonym slider give more control than a one-shot rewrite prompt
Backed by Learneo, a large education group, rather than an anonymous operator

Cons

Month-to-month Premium is about 2.4 times the annual rate, so the headline low price assumes a year up front
The site blocks automated access, so none of the figures here come from its own pricing page
The App Store listing itself disagrees on how many Premium paraphrase modes exist (8 versus 10+)
The heavy student use and the AI detector attract academic-integrity scrutiny that can rebound on users

Best for

Students and non-native writers rewording essays and emails sentence by sentence
Anyone who wants grammar, paraphrase, summary and citation tools in one browser extension
Occasional users, since the free tier handles short rewrites without an account upsell wall

Not for

Professional editing or long-form drafting, where a frontier chat model does more for the same money
Teams needing an API, admin seats or a documented data-processing agreement

Watch out: Prices here were read from the App Store listing, not the website; the web checkout may show different term lengths and promotions, and reviews mention the annual price doubling in 2025.
