Chess coaching, all in one app

Ask a coach what wears them out, and it is rarely the chess. It is keeping track of every student, and switching between apps in the middle of a lesson.

Every student, in order

Each student has their own course, homework and lessons, so you never need a spreadsheet to remember who is who.

  • A course for each student, built from topics and short units
  • Exercises that accept more than one right answer
  • Homework that shows how they thought, not only whether they were right
  • Your comments written beside their moves, and kept apart from theirs
  • Your weekly hours published once; students ask, you accept or decline
  • Invite a student by email, even before they have signed up

Teach live, with nothing to install

Send a link and begin. You both move the same board, see and hear each other, and what you played is kept with the unit it belongs to.

  • One board that either of you can move
  • Camera, microphone and chat beside the board
  • Arrows and highlights while you explain
  • A position or a whole game brought in from a PGN file
  • A summary afterwards, with everything you played

Book a lesson for later, or start one now.
