About QuillBot
QuillBot is an AI writing suite centered on rewriting. Its paraphraser rephrases text in several tones and styles, and around it sit a grammar checker, summarizer, plagiarism and AI-content detector, citation generator and a translator — available on the web, as browser extensions and in Word.
Its appeal is speed and clarity: students, writers and non-native English speakers use it to tighten drafts, avoid repetition and check grammar without switching between multiple tools.
