Guides
Plain-language guides to the open-source MiroFish engine, to synthetic audiences, and to testing a decision before it reaches real people. MiroFish.co.uk is an independent hosted service built on the open-source MiroFish project.
MiroFish
- What is MiroFish?: MiroFish is an open-source multi-agent simulation engine: AI personas discuss your material over several rounds. How it works, what it is for and its limits.
- How to use MiroFish: How to use MiroFish step by step: online with nothing to install, or self-hosted. What to give it, how to describe the audience, and what you get back.
- Is MiroFish free?: MiroFish is free open-source software, but running it is not: model usage, Zep and a server if you self-host, or a hosted plan. How the costs work.
- Is MiroFish any good?: What MiroFish does well, where it falls short (accuracy, varying results, invented report quotes, cost) and how to get good results, from a team that runs it.
- Self-hosted vs hosted MiroFish: what running it yourself actually takes: What running MiroFish yourself takes, from the upstream docs: Node.js 18+, Python 3.11 or 3.12, uv, a language-model key and a Zep key, or the fully local fork. And what a hosted service changes.
Synthetic research
- What is a synthetic audience?: A synthetic audience is a set of AI-generated personas that react to your material in place of real people. How it works, what research shows, and its limits.
Testing decisions
- How to test a price change before customers see it: Ways to test a price change before it goes live: interviews, Van Westendorp, Gabor-Granger, conjoint, live tests and a synthetic audience. When to use each.
- How to test a marketing message before you launch it: Ways to test a marketing message before launch: interviews, message-testing surveys, preference tests, small paid experiments and synthetic audiences.
