StarCraft II Replay AI Coach

A web-based replay viewer and coaching tool for StarCraft II that renders match replays outside the game client. It displays isometric map views with unit positions, economy graphs, army breakdowns, build orders, and battle timelines. The platform analyzes gameplay through an LLM to provide personalized coaching feedback, highlighting strengths and areas for improvement for each player.

The maker built the replay rendering engine from scratch using Claude Code, extracting position data and commands from replay files, then interpolating unit movements over time. An LLM processes this context to generate tactical critique and strategic recommendations tailored to individual player performance.
