Paraphrasing, grammar and summarizing in one writing suite
Reviewed by the the30top research team · Last reviewed 2026-10-27
Overview
QuillBot began as a paraphrasing tool and now bundles a paraphraser with 9 modes, grammar checks, a summarizer, citation generator, AI detector and a humanizer. Owned by Learneo since its 2021 acquisition by Course Hero, it has a usable free plan and a Premium plan at $8.33 a month billed annually. It rewrites and edits text you already have rather than writing long pieces from a brief, and free usage is capped, for example paraphrasing up to 100 words at a time.
