Overview

Bottom line

QuillBot is an AI writing toolkit built around a paraphraser that rewrites sentences in different modes, with a grammar checker, a summarizer, an AI detector, a humanizer and, on Premium, a plagiarism checker alongside it. It works in the browser and through extensions, a Word add-in and desktop and mobile apps.

It suits students and non-native English writers who rework source material and drafts every day and want quick alternatives for a sentence rather than a full rewrite. The free version is enough to try the paraphraser, grammar checker and summarizer on short passages.

The caveat is the size of a free request: paraphrasing stops at 100 words, and QuillBot says its limits can differ between the web app, extensions and apps.

Individuals buy Premium on the website, and organizations can choose a Team Plan with central billing and user management.
