LoopLedger
LoopLedger is a web app (with optional desktop wrapper) for building causal loop diagrams and turning them into lightweight, testable system models. Users sketch variables and feedback loops, then attach simple equations, delays, and assumptions to run quick “what-if” scenarios. The app focuses on practical decision-making: it flags reinforcing/balancing loops, highlights leverage points, and generates a plain-language narrative of how a change propagates through the system. It also supports versioning and scenario comparison so teams can track how their mental model evolves. This is a combination traditional + AI app: traditional modeling tools for structure, plus AI to help label variables, suggest missing links, and summarize model behavior. It’s not a full-blown system dynamics suite; it’s a faster, collaborative middle ground for product, ops, policy, and risk teams who need clarity more than academic rigor.
