The full review of QuillBot
QuillBot combines paraphrasing with tools for checking, summarizing, and supporting other writing tasks. It is a strong fit for writers who want a broad toolkit across devices, but the Free plan’s 100-word paraphrasing cap makes it better for brief edits than sustained drafting.
Overview
QuillBot started in 2017 as a paraphrasing tool for people learning to write in English and has since expanded into a suite spanning writing, communication, design, coding, and collaboration. That range can consolidate several writing tasks in one service, though users looking only for paraphrasing may find the broader product unnecessary.
The multilingual offering is a useful differentiator: Premium supports paraphrasing in 23 languages and translation into more than 40. QuillBot reports more than 35 million monthly active writers and 225 employees. Those figures suggest a substantial product, but the practical choice still turns on its limits and plan costs.
Key features
- Writing support: The toolset includes paraphrasing, grammar and plagiarism checking, AI detection and humanizing, summarizing, and citation generation. This breadth suits people who regularly move between drafting, revising, and checking work; it is less compelling if only one of those jobs matters.
- Free access: Free includes paraphrasing up to 100 words in two modes, basic grammar, basic summaries, and limited humanizing and AI Detector access. It is a useful way to handle short passages, but the word ceiling is restrictive for longer paragraphs or regular editing.
- Work across apps: QuillBot offers apps for macOS, Windows, Android, and iOS, plus Chrome, Edge, and Safari extensions. Its desktop app can appear as a widget in apps such as Slack, Notes, and Messages, and Premium includes a Word add-in. One subscription works across its apps, with Premium usable on up to 10 devices at a time.
- Team controls: The Team Plan adds writer-management dashboards and centralized billing to Premium features. QuillBot also says it does not train on Team Plan users’ text inputs, a meaningful distinction for organizations concerned about how work inputs are used.
Pricing
QuillBot uses a freemium model. Free is listed as free, billed per month. Its 100-word, two-mode paraphrasing cap and limited access to humanizing and AI detection make it a starter option, not a realistic substitute for paid use on longer work.
Premium is billed annually, but its price is not published. It includes 25,000 plagiarism-checker words per month, 6,000 words in Summarizer, 300 AI images per month, and 100 MB of Flow storage, alongside the Premium feature set. The monthly quotas help frequent users gauge capacity, but without a price it is difficult to assess the upgrade’s value before choosing it.
Team pricing is annual and includes all Premium features, dashboards for managing writers, and centralized billing:
- 2–10 seats: $750 a year, billed €89,95 every 12 months.
- 11–50 seats: $666 a year, billed €79,95 every 12 months.
- 51+ seats: $583 a year, billed €69,95 every 12 months.
The listed annual amount decreases as the seat band grows, making the larger tiers more attractive for bigger writing groups. Smaller teams get the same stated feature bundle but pay the highest listed annual amount. Priority assistance and account-management support are Team Plan benefits. QuillBot says user inputs and usage data may be used to provide and personalize the service and improve it through training; it says it does not sell user content or data, encrypts connections, and restricts access to customer data.
Platforms
QuillBot covers web, macOS, Windows, Android, and iOS, along with Chrome, Edge, and Safari extensions. That broad reach is useful for people who write on both computers and phones. It says it works toward GDPR compliance, abides by the CCPA, complies with PCI DSS, and is verified through CASA Tier 2.
Who it's for
QuillBot suits multilingual writers, students, and professionals who want paraphrasing alongside grammar, summaries, citations, and checking tools. Its cross-device access can help people who shift between desktop apps and mobile devices. Teams that need billing and writer management may benefit from the Team Plan, while occasional users may be well served by Free if their passages stay short. Writers routinely handling longer text should consider the paid plans, weighing the unpublished Premium price or the stated team tiers before committing.
Pros and cons
- Pro: Broad writing toolkit. Paraphrasing, grammar, plagiarism checks, AI tools, summaries, and citations cover more than rewriting alone.
- Pro: Wide platform coverage. Desktop and mobile apps, browser extensions, a desktop widget, and a Word add-in put the service in several writing contexts.
- Pro: Useful team administration. Dashboards and centralized billing address management needs beyond individual writing assistance.
- Con: Free paraphrasing is tightly capped. A 100-word limit in two modes is inadequate for many full-paragraph or longer edits.
- Con: Premium price is not published. Annual billing is stated, but users cannot compare the cost with its monthly quotas from the plan price alone.
- Con: Individual users may not need the breadth. Those seeking only a focused paraphraser may be paying attention to tools they will not use.
Alternatives
For a different fit, consider Trinka, Paraphrasing.io, RewriteGuru, Paperpal, Wordtune, Paraphrase Online, Clever AI Humanizer, and ParaFree.
Paraphrasing.io is worth considering if its free plan’s 8,000 credits and mix of paraphrasing, rewriting, summarizing, plagiarism checking, AI detection, and humanizing better match the work at hand. RewriteGuru offers a free 800-word rewriting limit, with spell and plagiarism checks also capped at 800 words, so it may suit users who want clearly stated free word limits. Wordtune’s Basic plan allows 10 rewrites and AI suggestions daily, three AI summaries monthly, and unlimited spelling corrections and grammar checks; it is a plausible choice for readers whose usage fits those allowances. Paraphrase Online has a free one-year Basic Plan and a yearly plan at $5.75 a year, billed $69 annually, with 120,000 submissions, five modes, 365 days, and 24/7 support; those terms may appeal to someone prioritizing its stated submission allowance.
Paperpal, Clever AI Humanizer, ParaFree, and Trinka are other options to compare.
QuillBot also sits within broader categories: browse Paraphrasing Tools, AI Paraphrasing Tools, AI Writing Tools, AI Summarizers, Translation Software, and AI Grammar Checkers.
Verdict
Choose QuillBot if you want paraphrasing plus a broad set of writing tools available across desktop, mobile, and browser contexts, or if your team needs writer management and centralized billing. Its principal drawback is the Free plan’s small paraphrasing allowance, compounded by an unpublished Premium price. If you need substantial free paraphrasing or want a paid option whose cost is clear upfront, compare alternatives before committing.
