Overview

QuillBot began in 2017 as a paraphrasing tool for English-language learners and has expanded into tools for writing, communication, design, coding and collaboration. That range can consolidate parts of a writing workflow, though users who need only one function may prefer a more focused tool. The company reports more than 35 million monthly active writers and 225 employees.

Its Premium comparison includes paraphrasing in 23 languages and translation into more than 40. That reach makes QuillBot relevant to multilingual work, but the free paraphrasing allowance is limited to two modes and short passages.

Key features

Writing and revision: The suite includes paraphrasing, grammar and plagiarism checking, AI detection and humanizing, summarizing, and citation generation. This breadth is useful for writers who move between drafting, revision and supporting tasks.
Free access: Free users can paraphrase up to 100 words in two modes, with basic grammar and summaries plus limited humanizing and AI Detector access. That is enough to sample the tools or handle short edits, not sustained work on longer drafts.
Cross-app workflow: QuillBot offers desktop and mobile apps, browser extensions for Chrome, Edge and Safari, and a Word add-in on Premium. Its desktop app can appear as a widget in apps such as Slack, Notes and Messages, reducing the need to move text between separate windows.
One account across devices: A subscription works across QuillBot apps and platforms; Premium can be used on up to 10 devices at a time. This is practical for people switching between work and personal devices.
Team administration and privacy: Team plans add writer-management dashboards and centralized billing. QuillBot says it does not train on Team Plan users’ text inputs, while inputs and usage data may otherwise be used to provide and personalize the service and improve it. It says it does not sell user content or data, encrypts connections and restricts access to customer data.

Pricing

QuillBot uses a freemium model. The Free plan is free, billed Per month. Its 100-word paraphrasing cap, two modes, basic grammar and summaries, and limited humanizing and AI Detector access make it suitable for occasional short tasks, but not a substitute for broader paid use.

Premium has no published 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. Those allowances may suit regular users who need the broader feature set, but confirm the price before choosing it; without that, the cost is difficult to weigh against the quotas.

Team plans include all Premium features, writer-management dashboards and centralized billing. The 2–10-seat plan is 750.00 USD per year, billed €89,95 every 12 months; the 11–50-seat plan is 666.00 USD per year, billed €79,95 every 12 months; and the 51+ seat plan is 583.00 USD per year, billed €69,95 every 12 months. The per-year amounts fall as seat bands grow, making the larger tiers more attractive to bigger groups. Team benefits also include priority assistance and account-management support. Teams should weigh those administrative and support features against the stated seat minimums.

Platforms

QuillBot lists apps for macOS, Windows, Android and iOS, alongside web access and Chrome, Edge and Safari extensions. The desktop widgets and Premium Word add-in extend it into other writing contexts. This broad coverage is a strength for people who work across devices; the single subscription and 10-device Premium allowance make that portability more useful.

Who it's for

QuillBot is a strong fit for students, multilingual writers and professionals who want paraphrasing alongside grammar, summaries, citations and checking tools. The free tier works for brief, occasional edits. Regular writers should consider Premium, but only after confirming its annual price and checking whether its quotas fit their workload. Teams that need centralized billing, writer management and support have a clearer use case for the Team plans. Users who need generous free paraphrasing or only one specialized tool may be better served elsewhere.

Pros and cons

Pro: A broad writing toolkit combines paraphrasing with grammar, plagiarism, AI detection, humanizing, summaries and citations, reducing the need to assemble separate tools for those tasks.
Pro: Desktop, mobile, browser and Word options make the service accessible across common writing contexts, with Premium usable on up to 10 devices.
Pro: Team features include management dashboards, centralized billing and priority assistance, which address administrative needs beyond individual writing.
Con: The Free plan's 100-word paraphrasing limit and two modes restrict its usefulness for longer passages or regular rewriting.
Con: Premium's price is not published, making it harder for individuals to assess the value of its annual subscription and quotas.
Con: QuillBot says non-Team inputs and usage data may be used to personalize the service and improve it, a consideration for users handling sensitive text.

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 billing and writer management. Its main advantage is the range of writing tools and platform coverage; its main drawbacks are the short free paraphrasing limit and an unpublished Premium price. Occasional users can start free, but frequent writers should verify Premium’s price and quotas before committing.
