LLM COACH · ALPHA
Ask about the match. Learn how to improve.

A StarCraft II expert knows the full replay and answers questions about decisions, turning points, builds, engagements, and composition.

PREDICTIVE NETWORK
Win probability, moment by moment

Our neural network, trained on tens of thousands of replays, shows how each decision changes the win probability.

ENGAGEMENTS
Understand every trade

Compare forces entering and leaving, lost composition, resources, actions and the win curve throughout the fight.

ECONOMY + PRODUCTION
See where the match was built

Track workers, income, bank, supply and production queues synchronized with the replay.

ARMY + TECH
Compare composition and upgrades

Open both players at the same instant and identify military and technological advantages.

ANALYTIC TIMELINE
Jump straight to what matters

Expansions, upgrades, supply blocks and engagements organized on a navigable timeline.

2D TACTICAL STATE
Spatial context without false precision

A reconstructed tactical view of units, bases and terrain to contextualize decisions — not an SC2 simulation.

COMMUNITY PROJECTBuilt by the community, for the community.

An experimental project for everyone who plays, studies and loves StarCraft II. Built transparently, open to feedback and improving replay by replay.

OPEN RESEARCHThe network will be open too.

The win-probability model will soon be released on Hugging Face with open weights. We will also publish a paper explaining its architecture, training process and how predictions are calculated.
