About SC2 AI Coach
Built by a StarCraft player. For StarCraft players. Free, forever.
The Philosophy
Every existing replay analysis tool either shows you raw numbers and leaves you to interpret them, or gives you so many charts that the actual insight is buried. SC2 AI Coach does something different: it reads your replay data with an AI and tells you, in plain language, what cost you the game.
The AI doesn't give you generic tips like "build more workers". It reads the actual worker count curve from your specific game, sees when you cut workers, and tells you that you cut workers at 5:22 and never recovered your saturation — that's the coaching.
What Makes It Different
Replay-Specific Advice
The AI reads the structured data extracted from your actual replay. It knows your APM, your build order, which battles you won and lost, and when your economy dipped.
Real Economy Graphs
Supply, workers, income, and army value are graphed over the game timeline. Scrub to any point and see where your economy diverged from your opponent's.
Every Engagement Detected
Every significant battle in the game is detected from kill event clusters. You get a timestamped list of fights, with resources lost per side.
Replays Saved Permanently
Every uploaded replay is stored in the database. Share the URL with friends, come back to it later, or compare replays across a session.
Team Game Support
2v2, 3v3, and 4v4 replays are stored and tracked alongside 1v1. Per-player stats are tracked even within team games.
