Frequently asked questions about QuillBot: AI writing companion
Is QuillBot free to use?
Yes, QuillBot offers a free plan that includes basic paraphrasing with a 125‑word limit, limited Humanizer usage, simple summarization, basic grammar checking, and a limited AI Detector, without requiring a credit card. However, some advanced tools and unrestricted access to features like unlimited paraphrasing and full plagiarism checking are reserved for paid Premium and Team plans.
What does QuillBot Premium include?
QuillBot Premium includes unlimited paraphrasing in all available modes, advanced grammar and style recommendations, unlimited Humanizer with human‑score and tone insights, custom summaries, an unlimited AI Detector, plagiarism‑prevention tools, full access to citation and academic‑writing features, and integration across browser extensions, desktop apps, and mobile keyboards. It also unlocks additional content‑creation tools such as cover‑letter generation, social‑media post writing, and certain AI‑driven design and PDF utilities.
Can QuillBot be used in mobile apps?
Yes, QuillBot offers mobile apps and a keyboard extension for iOS and Android that allow users to paraphrase, check grammar, and rewrite text directly within mobile apps and browsers. The mobile experience mirrors many web features, though some advanced tools or modes may be more limited or slightly slower compared to the desktop version.
Is using QuillBot considered cheating in academic writing?
Educational institutions set their own rules, but QuillBot is designed as an editing and writing‑assistance tool, not a way to generate someone else’s work. Many schools and instructors allow tools like QuillBot for paraphrasing, proofreading, and citation help as long as students still do the original thinking, research, and structuring. Users are encouraged to check their institution’s policies on AI‑assisted writing and plagiarism before relying on QuillBot for graded assignments.
Does QuillBot store my documents and data?
QuillBot may store certain documents and user content to power its tools, but it provides controls over account data and explains how information is handled in its privacy and terms policies. Users can often delete or manage their saved content, and QuillBot emphasizes that it does not automatically share documents with third parties without explicit consent, though details depend on current policy language available on its website.
Can QuillBot detect AI‑generated text?
QuillBot includes an AI Detector that analyzes text and estimates the likelihood it was written by an AI model, giving users a score or label to help judge originality. The detector is not foolproof and may produce false positives or negatives, so it is best used as a guide rather than a definitive proof of whether text is AI‑generated.
What languages does QuillBot support?
QuillBot supports paraphrasing, grammar checking, and translation in multiple major languages, including English, Spanish, French, German, Portuguese, and others, with coverage varying by tool. Translation and paraphrasing quality can differ by language pair, and some less common languages may have fewer modes or lower accuracy than English.
Does QuillBot work with PDFs and other file types?
Yes, QuillBot offers PDF‑editing tools such as ChatPDF, which lets users ask questions about PDF content, plus PDF editing, merging, reordering, rotating, splitting, extracting, and deleting pages, as well as file converters for Word, Excel, PowerPoint, and images. Users can upload or paste content from these file types to paraphrase, summarize, or analyze without leaving the QuillBot environment.
How does QuillBot integrate with browsers and Office tools?
QuillBot provides browser extensions for Chrome, Edge, and Safari that add a popup toolbar to rewrite text on web pages, and it also offers an add‑in for Microsoft Word so users can paraphrase and check grammar directly inside Word documents. These integrations aim to reduce copy‑paste steps and let users edit in context while maintaining document formatting as much as possible.
Is QuillBot suitable for professional and business content?
QuillBot is designed to support professional and business users with tools for drafting emails, reports, presentations, company blogs, and marketing copy, plus AI‑assisted brainstorming and content‑generation features. The platform also offers team and enterprise plans with centralized billing and user management, making it feasible to standardize writing quality and style across departments or organizations.
