About QuillBot

QuillBot is a writing assistant for people who want help revising, checking, or reshaping written work. Its tools address common writing tasks in one service: paraphrasing a passage, reviewing grammar, summarizing longer text, translating, or preparing citations. That makes it relevant to students, professionals, and other writers who need support at different stages of a draft, from shortening source material to checking language before sharing it.

Rather than focusing on only one kind of editing, QuillBot combines writing, language, and AI-related tools. Access to some capabilities differs by account type, and the available word limits matter when deciding whether it fits a particular task.

What can QuillBot do?

The Paraphraser offers Standard and Fluency modes to free users; Premium adds nine preset modes and custom modes. The Summarizer handles up to 1,200 words on Free and up to 6,000 words on Premium, with custom summaries available on Premium.

  • Grammar Checker provides basic fixes on Free and advanced recommendations on Premium.
  • Translator supports more than 40 languages; Premium paraphrasing is available in 23 languages.
  • Other listed tools include an AI Detector, AI Humanizer, Citation Generator, AI Chat, and AI image generation.
  • Premium plagiarism checking has a monthly limit of 25,000 words.
  • Premium access includes Chrome and Edge extensions, a macOS app, a Word add-in, and Android and iOS apps or keyboards.

QuillBot also offers QuillBot Flow storage: the verified help page lists 10 MB for Free and 100 MB for Premium. Feature access and allowances should be checked against the relevant official page, as the verified pages differ on the Free paraphrasing word limit.

Who is QuillBot best for?

QuillBot may suit students working with summaries and citations, professionals revising messages or documents, and writers who want paraphrasing and grammar tools alongside translation. People handling longer summaries or needing custom modes, advanced grammar recommendations, plagiarism checking, or the full Humanizer and AI Detector access should compare those Premium features with their needs. Teams can consider the separate team features if shared administration and billing matter.

QuillBot pricing in brief

QuillBot has a free option and paid individual access, with team plans for organizations that need seats and shared administration. Official pages show several paid plan displays, and the Premium page notes that pricing and limits may vary by surface. Check the current official pricing page for the applicable offer and terms before choosing.

Limitations to know about QuillBot

Free access has narrower allowances: two paraphrasing modes, limited access to the Humanizer and AI Detector, and summaries up to 1,200 words. The official pricing page lists a 100-word Free paraphrasing limit, while the help page lists 125 words, so the exact allowance is not consistent across the verified pages. Premium plagiarism checking is also limited to 25,000 words per month. These limits may affect longer or repeated tasks.

Alternatives to QuillBot

Grammarly is an alternative to compare for writing and grammar assistance. Wordtune is another option to compare for rewriting and revising text. These tools are listed as alternatives for similar writing tasks; their specific capabilities are not established by the QuillBot facts used here, so compare their own product information before deciding.
