Analyze your chess games into commented videos

Observed in the wild: the builder recorded themselves thinking aloud during a 15+10 rapid game, then gave Claude Code the Lichess link and the mp3. Claude transcribed it locally with whisper.cpp and matched sentences to moves powered by PGN clock times. It produced an annotated PGN, an HTML board and a 6:49 narrated video with subtitles for The builder's real game.
