This paper presents Sketch Sync, a real-time collaborative whiteboard web application built using Next.js. With the rise of remote work and digital collaboration, there is a growing need for effective tools that enhance user interaction and creativity. Sketch Sync allows multiple users to interact, draw, and communicate on a shared virtual canvas in real Time. Utilizing Next.js for the front end and Socket.IO for real-time synchronization, the application ensures a fast and responsive user experience. Studies show real-time groupware improves collaboration efficiency, making Sketch Sync ideal for online classrooms, brainstorming, and creative sessions. This paper highlights Sketch Sync’s key features, including a user-friendly interface, drawing tools, and real-time chat, while addressing challenges such as performance optimization and cross-browser compatibility. Additionally, we explore its applications in education, design, and remote teamwork. By bridging traditional brainstorming methods with digital solutions, Sketch Sync enhances productivity and fosters seamless collaboration
