Mirofish

Mirofish is an academic research tool. An open source multi-agent simulation engine that builds a parallel digital world from seed data, lets thousands of persona-driven agents interact, and returns a prediction report plus a world you can question directly. Positioned for finance, policy, PR, marketing, research and fiction deduction, with a hosted online edition still on the waitlist.

MiroFish is an open source swarm intelligence engine built around multi-agent simulation. Rather than extrapolating trends from historical data alone, it takes seed materials from the real world (breaking news, draft policies, financial signals, novel chapters) and builds a parallel digital world inside which thousands of agents with independent personas, long term memory and behavioral logic interact and evolve socially. The premise is that group behavior emerges from individual interaction, and that rehearsing that emergence in a sandbox gives a better read on what happens next than a single statistical model can. In practice the workflow is a five stage pipeline. Graph construction extracts the reality seed and injects individual and collective memory into a GraphRAG structure. Environment setup pulls out entity relationships, generates personas and configures simulation parameters. The simulation then runs on two platforms in parallel, auto-parsing your prediction request while temporal memory updates on the fly. A ReportAgent equipped with a toolset examines the post-simulation environment and produces a prediction report. Finally you can interrogate the result directly by chatting with any individual agent in the simulated world or with the ReportAgent itself. The intended audience is broad by design. The site positions it for financial decision support and investor sentiment rehearsal, policy opinion forecasting for government and think tank users, crisis PR simulation for enterprises, marketing strategy testing, academic research on information propagation, and story or fiction deduction, including a demo that predicts a lost ending for Dream of the Red Chamber from its first eighty chapters. That spread is the product's stated thesis: the same simulation machinery serves serious forecasting and playful what-if exploration. Where it fits among alternatives is less clear from the homepage. MiroFish is not an LLM wrapper or a chatbot with search; it sits closer to agent based modeling tools, which usually demand programming and domain modeling expertise. MiroFish claims end-to-end automation and natural language input for that class of work. The catch is maturity: the project is open source and self described as heading toward an online edition that has not launched, with a waitlist in place, so most users will meet it as a repository rather than a hosted service.
