Users paste text into the QuillBot paraphraser, select a paraphrasing mode (Standard, Fluency, Formal, Simple, Creative, Expand, or Shorten), and generate a rewritten version. Synonyms are highlighted and can be changed individually. The summariser condenses longer texts to key points. The grammar checker identifies and corrects errors inline. The citation generator produces formatted academic references from URLs, DOIs, or book details. All tools are accessible within the QuillBot web interface or extension.
QuillBot
QuillBot is an AI writing assistant tool specialising in paraphrasing, grammar correction, summarisation, and citation generation. It is widely used by students, academics, and professional writers as a writing improvement and rewriting tool rather than a full content generator.
The core paraphrasing engine allows users to rephrase text while preserving meaning — useful for improving readability, reducing repetition, or adapting a writing style. QuillBot has expanded to include a full suite of writing tools: a grammar checker, summariser, plagiarism checker, citation generator, and a translator.
It is available as a browser extension integrating with Google Docs and Microsoft Word, as well as a standalone web application, making it accessible across common writing environments.

How It Compares
QuillBot's primary competitors are Wordtune and Grammarly in the rewriting and editing space. Wordtune focuses specifically on sentence rewrites and tone adjustment. Grammarly emphasises grammar correction and style improvements. QuillBot differentiates on its paraphrasing depth and academic tool suite (citation generator, summariser). For full content generation rather than rewriting, tools like Jasper or ChatGPT are more appropriate.
