About the company
QuillBot was founded in 2017 by Rohan Gupta, Anil Jason and David Silin — three students who built a paraphraser for their own coursework — and was bought by Course Hero in 2021. Its job is narrow and honest: not writing from scratch but rewriting somebody else’s paragraph and proofing your own. Plagiarism checking, an AI-text detector and grammar grew around that. It is the cheapest paid access among the writing tools here at four dollars a month on annual billing, and its free tier is capped at a hundred and twenty-five words at a time but adds no watermark.
