What they did
A user built a chess tutor with Grok Bot. It pulls every rapid game from their account through the site's free public API, runs each one through Stockfish 17 to mark blunders, mistakes and inaccuracies, and reads the clock on every move. It sorts errors into themes like hung pieces, missed tactics and time trouble, writes a lesson plan with their top 3 problems and real examples, and books two 45-minute study slots in their calendar.
How it went
The first run over 200 games found only 1 of 90 losses was on time, and 160 of the blunders were just leaving a piece hanging. They say everything except the engine is free and it's a weekend build.
Worth knowing
- Self-reported X post; the setup details make it easy to repeat. Next step they mention, a nightly run, wasn't built yet.

Pull my last [200] rapid games from [chess site] using its public API. Run each through a chess engine and mark blunders (300+ centipawns), mistakes (100-299) and inaccuracies (50-99), and note the clock. Group my errors into themes with game links, move numbers and the better move. Write a lesson plan with my top 3 problems and a short weekly practice list, then put two study sessions in my calendar.
