Capsule is an open-source engine for causal consequence modeling. The demo: zoom into a 3D globe at 2000 BC, change one thing, zoom out, watch consequences ripple across the planet. Click any city to see a causal chain back to your decision. Decisions across 6,000 years. The engine is domain-agnostic (supply chains, ecosystems, urban planning, etc.). Includes the first open-source benchmark for causal reasoning in LLMs.
