On-device AI
A companion, not a dependency.
Each engine remains the authority on legal moves and outcomes. A model may choose among legal actions, explain a position or speak in character; it never gets to invent the rules. When a model is unavailable, deterministic or rules-based fallback keeps the game playable and says what changed.
Conversation availability depends on Apple's local model and language coverage. The game interface can be localized more broadly than the current conversation model, so the site does not imply that every AI voice speaks every supported UI language on day one.
