QuillBot

QuillBot is an AI-powered writing assistant that specializes in paraphrasing, grammar checking, and text refinement. Developed by Course Hero, it helps students, professionals, and non-native English speakers improve their writing clarity, originality, and style through a suite of interconnected tools — all accessible from a clean, browser-based interface.

QuillBot's core tool is its Paraphraser, which rewrites text using multiple modes including Standard, Fluency, Formal, Simple, Creative, Expand, and Shorten. The Grammar Checker identifies and corrects grammatical errors, punctuation issues, and awkward sentence structures. The Summarizer condenses long texts into key points or paragraph form. The Plagiarism Checker scans content against billions of web sources to ensure originality. The AI Humanizer helps make AI-generated text sound more natural. The Translator supports over 45 languages with AI-enhanced consistency. Additional tools include a Citation Generator, Tone Detector, and Co-Writer for longer-form composition.
