Notation is a chess coaching app that teaches you why — not just what.
Every chess evaluation comes from Stockfish 18, running entirely on your device. Every pattern, weakness, and tactical motif is detected by hand-tuned on-device classifiers built on decades of coaching theory. The language model's only job is the last step: explaining what the analysis found, in plain English, like a coach sitting next to you.
The chess is never generated. It's explained.
THREE COACHING FRAMEWORKS
Notation is the first chess app to operationalise multiple grandmaster-level coaching frameworks as deterministic measurement:
• Dan Heisman's seven positional elements — Mobility, Vulnerability, Centre Control, Coordination, Speed, Time, Flexibility — measured per-position with super-GM baselines
• Jeremy Silman's coaching emphasis frames — fifteen frames choosing what to teach at each moment
• Jacob Aagaard's positional predicates — Where are the weaknesses? Which is the worst-placed piece? What's the opponent's plan?
All computed on-device. All deterministic. The same principles human coaches have used for decades, encoded into classifiers that run before the language model ever sees the position.
GAME REVIEW
Every game gets a coherent on-device review — no API key needed, no internet, no cost. Template-driven narrative against the full coaching substrate. When you want depth, upgrade once with your own Anthropic or OpenAI API key, o ruse the On Device LLM with no additional costs and the richer review becomes the permanent artefact for that game. Nadia comments on at most six moments — only the ones worth learning from. PDF export of every review.
PLAYER PROFILE
Style axes — Aggression, Tactical Alertness, Positional Play, Endgame — derived from the substrate with confidence bands. The seven Heisman elements sit below as evidence. Full-screen iPad dashboard. PDF coaching report you could hand to a human coach.
OPPONENT SCOUTING & MATCHUP REPORTS
Scout reports surface the full eight-axis substrate on any opponent. How-to-play-against framing with concrete suggestions. Player-vs-opponent comparison across all axes with weakest-phase detection.
SHADOW — YOUR CHESS TWIN
