Adaptive builds, every game

Our model evaluates game state (enemy comp, gold differential, team needs) and suggests an item path for your situation.

Contextual Branching

vs Healing

The model branches based on game context. Different games can produce different build paths.

Specific to the game

Computed from 298 features: your champion and items, gold/XP, objectives, lane state, and team comps. As the game changes, the suggestions can change too.

How it works
Performance Analysis

Cause, not correlation

We use causal inference (DoubleML) to estimate how different behaviors affect rank.

Average Treatment Effects

Causal effects estimated from large-scale match data

Positive causal effect
Negative causal effect

CATE vs ATE

Conditional treatment effects

ATE tells you what works on average. CATE tells you what works for you. Using DoubleML, we estimate individual-level causal effects conditioned on your playstyle, champion pool, and rank.

37 Behavioral Signals

Champion pool, builds, timing, tilt

We compute a set of behavioral signals from your match history: champion focus, build choices, skill order patterns, play-after-loss behavior, and more.

Correlation Misleads

Correlation mixes skill and cause

Correlations often say "good players do this," not "doing this makes you win." Causal estimates aim for the second, controlling for skill and context.
