Overview

QuillBot began in 2017 as a paraphrasing tool aimed at helping English-language learners write. It has expanded into tools for writing, communication, design, coding and collaboration. That breadth makes it more useful as a general writing toolkit than as a dedicated paraphraser, though its appeal depends on whether you will use the extra functions.

The company reports more than 35 million monthly active writers and 225 employees. QuillBot supports multiple languages; Premium includes paraphrasing in 23 languages and translation into more than 40. That coverage is relevant for multilingual work, but the free paraphrasing allowance remains narrow.

Key features

Writing and revision: Paraphrasing is joined by grammar and plagiarism checking, AI detection and humanizing, summarizing, and citation generation. This range suits users who want several writing tasks in one toolkit rather than a single-purpose rewriter.
Free access: Free allows paraphrasing up to 100 words in two modes, alongside basic grammar and summaries, with limited humanizing and AI Detector access. It works for brief edits and trying the service; longer passages quickly run into the cap.
Cross-platform workflow: Desktop apps are available for macOS and Windows, mobile apps for Android and iOS, and browser extensions for Chrome, Edge and Safari. The desktop app can appear as a widget in Slack, Notes and Messages, while Premium includes a Word add-in. One subscription works across apps, and Premium can be used on up to 10 devices at a time.
Team controls: Team plans include Premium features, writer-management dashboards and centralized billing. QuillBot says it does not train on Team Plan users’ text inputs, a meaningful distinction for organizations considering shared use.

QuillBot says it encrypts connections, restricts access to customer data, does not sell user content or data, works toward GDPR compliance, abides by the CCPA, complies with PCI DSS and is verified through CASA Tier 2. It may use user inputs and usage data to provide and personalize the service and train improvements, so individual users should weigh that use against their privacy requirements.

Pricing

QuillBot uses a freemium model. The Free plan is free, billed per month. It includes the 100-word, two-mode paraphraser, basic grammar and summaries, and limited humanizing and AI Detector access. That is a low-commitment option for occasional short edits, not a practical allowance for regular long-form rewriting.

Premium has no listed price and is billed annually. Its stated quotas include 25,000 plagiarism-checker words per month, 6,000 words in Summarizer, 300 AI images per month and 100 MB of Flow storage. The multilingual paraphrasing and translation coverage, plus the Word add-in and 10-device allowance, make it the fuller individual option, but a reader cannot compare its cost with those quotas before choosing it.

Team pricing is billed every 12 months and scales by seat count. Team Plan (2–10 seats) costs 750.00 USD per year (billed €89,95 every 12 months); Team Plan (11–50 seats) costs 666.00 USD per year (billed €79,95 every 12 months); Team Plan (51+ seats) costs 583.00 USD per year (billed €69,95 every 12 months). Each includes all Premium features, writer-management dashboards and centralized billing. The larger tiers have lower stated prices, so they suit larger groups better than a small team; the figures present USD and euro amounts together, which buyers should account for when budgeting.

Platforms

QuillBot runs on the web, macOS, Windows, Android and iOS, with Chrome, Edge and Safari extensions. This breadth favors writers who switch between desktop and mobile work. Widget access in apps such as Slack, Notes and Messages adds convenience for short edits in context, while the Word add-in extends the Premium workflow into a word processor.

Who it's for

QuillBot is a strong fit for students, multilingual writers and individuals who need a mix of paraphrasing, grammar, summaries and citation support. Teams may value the dashboards, consolidated billing and stated input-training distinction. It is less suitable for anyone who regularly needs to paraphrase substantial text on the free tier, or who needs to compare an individual Premium price before committing.

Pros and cons

Pro: A broad set of writing tools combines paraphrasing with grammar, plagiarism, AI and citation functions, reducing the need to switch between separate writing utilities.
Pro: Desktop, mobile and browser options, plus use across up to 10 devices for Premium, support writers who move between platforms.
Pro: Team dashboards, centralized billing and no training on Team Plan text inputs address practical group-management and privacy concerns.
Con: Free paraphrasing stops at 100 words and two modes, which limits usefulness on longer drafts.
Con: Premium is billed annually but has no listed price, making the value of its larger quotas difficult to judge in advance.
Con: Individual inputs and usage data may be used for service personalization and improvement training, which may not suit every privacy preference.

Verdict

Choose QuillBot if you want a broad multilingual writing toolkit that follows you across desktop, mobile and browser workflows, or if your team needs shared administration. The main reason to look elsewhere is the combination of a tight free paraphrasing cap and an unpriced annual Premium plan: occasional users can start free, but frequent writers need clearer individual pricing before they can make a confident paid choice.
