Groupboard

The platform offers a browser‑based whiteboard that supports real‑time drawing, chat, and document upload, with additional tools such as drag‑and‑drop, pan/zoom, undo, and a built‑in Desmos graphing calculator for math tutoring. Integrated audio/video conferencing and screen sharing allow participants to discuss and present content without installing plugins, while shared code editing enables collaborative programming sessions. Optional session recording and playback let users capture meetings for later review, and multiple rooms can be created to organize separate discussions.

It is targeted at online tutors, educational institutions, and tutoring businesses that need a unified environment for instruction and collaboration. The software runs on any modern web browser across desktop and mobile operating systems, including Windows, macOS, Linux, iOS, and Android, and can be deployed either as a hosted cloud service or self‑hosted on a private server.

Distinctive aspects include a long history of development since 1998, a proprietary license with a free tier that requires no registration, and the ability to embed the whiteboard in external websites. The solution emphasizes stability, scalability, and a feature set tailored to math tutoring and general collaborative work.
