About QuillBot
Quillbot is an AI writing platform that helps students, professionals, and writers improve their work through a comprehensive suite of tools. The platform includes paraphrasing to rephrase text while maintaining meaning, grammar checking for spelling and syntax errors, AI detection to identify AI-written content, and originality checking through plagiarism detection. Beyond text tools, Quillbot offers content creation features like image generation, presentation building, cover letter generation, and social media post writing. The platform distinguishes itself through seamless integration across multiple devices and applications—available as browser extensions (Chrome, Edge, Safari), mobile apps (iOS, Android), desktop applications (Windows, macOS), and Word add-ins. Users can access Quillbot anywhere without switching between tools. The service has grown to serve over 35 million writers across 180 countries and partners with 140+ institutions, indicating significant adoption in educational and professional sectors. One limitation is that core features require account creation for most advanced functionality, though a free tier exists with limited daily usage.
