On Bases, or with The Horde → Pianist: builds, directs armies, contests flags, uses heroes and Q/W/E. Difficulty changes attention, not gold or combat stats. Pianist skill stays separate.

Works offline without a model. Optional local Ollama requires server setup; unavailable models fall back to the local bot. No paid API calls. Add ?aiDebug to inspect decisions.

Your units are made in this order, again and again. Tap a slot to change it.
