What is QuillBot?
QuillBot offers a set of writing tools in one place: a paraphraser that rewrites text in different modes, a summarizer, a grammar checker, an AI content detector and other helpers. The free tier is usable without heavy limits on basic tasks, while Premium removes word caps and unlocks all paraphrasing modes.
Rewording, condensing or checking text by hand is slow, especially for students and non-native writers.
