Overview
QuillBot AI is a writing and plagiarism-checker software for students, researchers, and professionals who need paraphrasing, grammar checking, and originality reports in one place. Its paraphraser offers seven modes including Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten, while the grammar checker fixes spelling, punctuation, and syntax. The plagiarism checker compares text against a large database to flag unoriginal content, and an AI content detector identifies ChatGPT or Gemini-generated writing.
