Rehearse what comes next.
FNDX turns your sources into a living simulation, so you can test a decision before the world does.
Illustrative animation. Move your cursor to disturb the network.
Decisions meet people, and people react to each other.
- Surveys record what one person says when asked.
- Reports explain what has already happened.
- Neither shows what happens when a reaction spreads.
A rehearsal room for decisions that matter.
Start with a question and the documents behind it. FNDX maps what they describe, creates personas who could plausibly be affected, and lets them act out the situation round by round.
You then read what happened, check findings against your sources, and ask the personas why they acted as they did.
It is a simulation, not a forecast. Its value is showing what could happen and what would drive it.
From a folder of sources to a conversation with the outcome.
Sources
Add the documents, reports and context your question depends on.
Knowledge graph
FNDX extracts people, organizations and their relationships into a graph you can inspect.
Personas & environment
Generate personas from that graph or write your own, then set the conditions they act in.
Simulation
Personas post, reply and react to one another on simulated social platforms.
Report & interviews
Read a report tied to its sources, then question individual personas or the whole group.
Inside FNDX
The workspace follows each study from its sources to its conclusions.
- Knowledge map
- See what FNDX extracted from your sources and how it connects.
- World view
- Follow who wrote what, who replied, and read each persona's reasoning.
- Method limits
- Every result states how far it can be trusted.
Six ways to ask the question.
Social simulation
Your question and the sources behind it
How personas talk and react, with a report you can question
Controlled experiment
Two versions of a message or presentation
How the same personas respond to each version
Product research
A product idea and the people it is for
Structured persona feedback on the idea
Process scenario
Capacity and demand assumptions
How waiting changes across the options you set
Video research
A video you want to study
A transcript-based source and a report built on it
Probability study
Numeric options and your assumptions
A comparison across 50 to 50,000 repeated runs
Built so you can check the work.
- Separate by company
- Each company runs its own engine process with its own data area.
- Traceable findings
- Reports cite the sources you provided, so you can check what they rest on.
- Your own model
- Connect an OpenAI-compatible model and memory service with your own API keys.
- Open foundations
- The simulation engine builds on the open-source MiroFish and OASIS projects.
- Honest about limits
- Personas are models, not real people. Treat results as evidence to weigh, never as a guarantee.
Your next decision deserves a rehearsal.
