A browser-only collaborative classroom environment that enables tutors and teachers to give live remote courses to students.

It includes a collaborative whiteboard, video and audio chat capabilities, and desktop sharing. Developed as a SaaS platform so that any software can embed and use the online classroom transparently as if it is part of that software.

It is developed with React and Redux on the front end and Node.js on the back end. WebRTC is used for video conferencing.
