About QuillBot
QuillBot is a writing tool known for its paraphraser, which rewrites a sentence or paragraph in different words. It also includes a grammar checker, summarizer, citation generator and translator, and is available on the web, as a browser extension and in apps.
A free version has limits on how much text you can process, and a Premium plan lifts them and adds more modes. Paraphrasing someone else's work does not remove the need to cite it, and many schools have rules about AI-assisted writing, so follow your institution's policy.

❓ Frequently Asked Questions about QuillBot
What is QuillBot?
QuillBot is a writing tool best known for its paraphraser, which rewrites a sentence or paragraph in different words. It also includes a grammar checker, summarizer, citation generator and translator, and is available on the web, as a browser extension and in apps.
Is QuillBot free?
There is a free version with limits, such as a cap on how much text you can process at once, and a paid Premium plan with fewer limits and more modes. Limits and prices change, so check QuillBot's site for current details.
Does paraphrasing with QuillBot count as plagiarism?
Rewording someone else's work does not make it yours. If the ideas come from a source you still need to cite it, and many schools and publishers have rules about AI-assisted writing, so follow your institution's policy and disclose where required. Use it to improve your own drafts rather than to disguise copied text.
Can QuillBot detect AI writing or plagiarism?
QuillBot offers an AI content detector and a plagiarism checker. No AI detector is fully reliable: they can flag human writing and miss AI text, so do not treat one result as proof.
