Drill pace — how many due lines per day
The most overdue lines always come first, so nothing gets lost — a lighter pace just spreads them out. No review avalanches.
Your notebooks are yours — take everything with you any time, no lock-in. Notebooks download as a PGN file (opens in any chess app); the full backup also includes your drill progress, puzzles and settings.
Optional — connect your free Lichess account to see 🌍 What players do here: real-game popularity and win rates for every position in the Analysis panel. Lichess calls the key a “personal API token”: create one at lichess.org → API tokens (just tap Create — no permissions needed), then paste it below. It stays on this device only.
Hand a code to your class: students tap Sign in at the top of the page, then 🎒 Join with a class code, and enter it with just a first name — no email, no account setup, nothing to install. They appear under your students automatically.
Add the email address of anyone you want as an instructor. They sign in with that email and can view the notebooks you share, comment on your moves, and add variations. Choose which notebooks they see with ⋯ → Share with instructors inside each notebook. Remove an instructor any time.
🎒 Join your coach's class
No email needed — enter the class code your coach gave you, and your first name so they know it's you. This device remembers you afterwards.
