About QuillBot
QuillBot is best known for paraphrasing, but its tool list also includes a grammar checker, AI detector, plagiarism checker, summarizer, citation generator and AI chat. Its Chrome extension brings paraphrasing and grammar checks into other web pages, and the site's create area produces presentations, resumes and images.
The Chrome extension is free to add, which makes it the simplest way to try the grammar checks. The site offers an upgrade to Premium, and its pricing terms are not shown on the pages checked. QuillBot's tools focus on single passages and rewriting. The site does not describe manuscript-level style reports, so long manuscripts need a different editor.
