About QuillBot

QuillBot is the go-to paraphrasing and writing tool for students and professionals. Its signature feature rewrites any passage in multiple modes — from 'Standard' to 'Fluency' — so you can express the same idea differently while keeping the meaning intact.

Beyond paraphrasing, it offers a full writing toolkit: grammar checker, summarizer, citation generator, plagiarism checker, and a translator. The browser extension brings these tools to every site you write on.

If English is not your first language, or you write long documents and need to avoid repetition, QuillBot is one of the most practical AI tools you will ever install.

QuillBot: strengths and trade-offs

Our own read on the product — written from the vendor’s documentation and our use of it, not from a vendor brief.

What it does well

  • The paraphraser is still the most useful single feature of its kind — the slider between formal and simple is genuinely practical.
  • Summariser and citation generator are included in the same subscription, which covers a lot of student workflow in one place.
  • Free tier is usable for short pieces without an account.

Where it falls short

  • Output has a recognisable house style; unedited paraphrased text reads like paraphrased text.
  • Academic-integrity tooling increasingly flags heavy paraphraser use, which is a real risk for students.
  • It rewrites sentences but cannot fix a weak argument or a badly structured essay.

Who should skip QuillBot

  • Anyone whose submission will be checked by an AI-detection or integrity tool.
  • Writers needing net-new content rather than a rewrite of existing text.

Check Pricing

How this listing was checked

  • Source. Pricing, plan names and feature details come from the vendor’s own product and pricing pages — for this tool, QuillBot — plans. This listing was last edited September 12, 2026.
  • Prices change. AI pricing and free tiers move faster than almost any other software category. Treat the figure here as a starting point and confirm it at the source before you buy — we re-check listings on a rolling schedule but cannot promise a page is current on the day you read it.
  • Independence. No vendor paid for this page or for its position, and no vendor reviews it before publication. See our review methodology and advertising disclosure.
  • Corrections. Found something wrong or out of date? Tell us — verified errors are corrected and dated.
