QuillBot
Reword, summarise and polish text you have already written.
About
QuillBot is an AI writing suite built around paraphrasing: it rewrites sentences and paragraphs in a different wording while keeping the meaning intact. Around that core sit a grammar checker, a summariser, a citation generator, a plagiarism checker and an AI detector. It is especially popular with students and academics who need to rephrase and tighten their own drafts.

- Grammar checker with basic corrections free and deeper suggestions on Premium
- Summariser that condenses long articles and documents into key points
- Plagiarism checker on Premium with a monthly word allowance

Best for
Students, researchers and professionals who need to reword, summarise and clean up existing text.
Limitations to know
Paraphrasing can subtly change meaning, drop nuance, or produce wording that reads smoothly but says something different from the original, so every rewrite needs a careful re-read. AI detection is also unreliable, and no detector result should be treated as proof about who wrote a text.
