In their own words
ClassLab
ClassLab is a digital campus for students, bringing together a feed, community chat, watch parties, focus tracking, mind maps, an exam calendar and an AI study assistant. Focus tools track Deep Focus, Class or Break sessions, show a daily timeline and tracked hours, and let students set goals. Watch parties synchronize YouTube videos or playlists, with live chat and a shared queue; hosts can manage participants. Mind maps help students organize a syllabus, connect topics and pin YouTube videos. The assistant uses a student's exam and preparation profile, focus sessions, tasks and milestones to tailor study plans, explanations and quizzes. ClassLab says account data is used only to personalize that user's assistant responses, not to train models. Users can connect assistants such as Claude or ChatGPT to their ClassLab tasks. Onboarding offers CAT, JEE, NEET, SSC/UPSC, Banking and Railways tracks. It is available on Android, iOS and web, works in mobile browsers and can send push notifications for messages, mentions and events. Watch parties run in the browser without installs. A free student account includes the listed study features.
