# MiroFish

> MiroFish is an open-source, multi-agent AI simulation for scenario prediction. Ask a what-if question in plain language; MiroFish builds a knowledge graph of the actors, runs them as autonomous AI agents on a simulated social surface, and returns a prediction report you can keep questioning. It is exploratory decision support, not a guaranteed forecast.

Canonical name: MiroFish (one word). Common misspellings that refer to the same tool: Miro Fish, MicroFish, Micro Fish, Mirror Fish, Mira Fish, mirofihs.

## Guides (English)
- [What is MiroFish?](https://mirofish.ink/what-is-mirofish): MiroFish is an open-source multi-agent AI simulation that turns a what-if question into a knowledge graph, a crowd of AI agents, and a prediction report you can question.
- [How to use MiroFish](https://mirofish.ink/how-to-use-mirofish): A practical walkthrough of running your first MiroFish simulation: write a sharp question, seed it with real actors, run the multi-agent simulation, and read the prediction report.
- [Using MiroFish online](https://mirofish.ink/mirofish-online): Run MiroFish in your browser at mirofish.us — the full multi-agent prediction workflow with no Docker, no GPU, and no API keys. Here is what the hosted version does.
- [Multi-agent simulation, in plain terms](https://mirofish.ink/multi-agent-simulation): Multi-agent simulation models many autonomous agents interacting so that group behaviour emerges instead of being scripted. Here is how MiroFish uses it to predict reactions.
- [AI scenario simulation](https://mirofish.ink/ai-scenario-simulation): AI scenario simulation rehearses how people react to an event before it happens. See how MiroFish turns a what-if question into a testable prediction report.
- [Public-opinion simulation](https://mirofish.ink/public-opinion-simulation): Simulate how public opinion forms and spreads after an event using AI agents. See which group reacts first, how narratives compete, and where sentiment settles.
- [Inside a prediction report](https://mirofish.ink/prediction-report): What a MiroFish prediction report contains: an executive summary, risk signals, narrative paths, and follow-up questions — plus a world you can keep interrogating.
- [MiroFish vs traditional forecasting](https://mirofish.ink/mirofish-vs-traditional-forecasting): How multi-agent simulation compares to trend lines and survey-based forecasting — and when a MiroFish rehearsal tells you something a forecast number cannot.
- [World Cup prediction with MiroFish](https://mirofish.ink/mirofish-world-cup-prediction): Use MiroFish to build an evidence-led World Cup match forecast: feed in form and context, simulate the decisive moments, and see what could reverse the result.

## Key facts
- Type: multi-agent / agent-based simulation for scenario and public-opinion prediction.
- Workflow: seed question or file -> knowledge graph -> multi-agent simulation over rounds -> prediction report -> follow-up chat.
- Best for: launches, pricing changes, policy debates, market narratives, and other outcomes that depend on how a crowd reacts.
- Honesty: outputs are exploratory rehearsals, not guarantees or financial advice.
