Watch your system dynamics model flow, not just chart
Nirai is an innovative system dynamics visualization tool that transforms traditional line-chart results into immersive, animated water flow simulations. Designed for modelers, educators, and analysts, it brings stock-and-flow diagrams to life by visually representing water moving through tanks and pipes, making feedback loops, bottlenecks, and system behavior instantly understandable. Unlike conventional tools that require interpreting numerical data, Nirai offers a dynamic, real-time visual experience that enhances comprehension and engagement. Its fully browser-based architecture, powered by Rust/WASM, ensures fast, smooth performance without the need for downloads. Additionally, users can export entire simulations as MP4 videos, ideal for presentations, slides, or explainer videos. The platform also features AI-driven model editing via API integration, making it adaptable and user-friendly for a diverse range of users interested in system thinking, data visualization, and animated storytelling.
