Built for the way coaches work
One place for the class, the homework and the follow-up.
Most coaches juggle a video call, a board site, a spreadsheet and a chat app. NabuChess is all of it, built around chess.
Live classroom
Every student on their own board.
Ask a puzzle and watch every board at once. You see the right moves, the wrong ones, and who hasn't started, without screen sharing or raised hands.
- Video, chat and your board in one window
- Puzzle challenges with live scores
- Arrows and highlights reach students instantly
- Class puzzle rush, simuls and play pairs
