Welcome

Stigmery is a browser-based tool for agent-based modeling - building worlds out of many small, rule-following entities and watching what patterns emerge.

It is inspired by NetLogo but built around two ideas:

A declarative model that you can read, edit by hand, save, and share.
An AI copilot that understands the same model and can build or tweak

it in plain language.

You don't have to choose between them. The same actions an expert user takes through the UI are the same actions the AI takes through its tools. Watching the AI work is one of the better ways to learn the system.

This guide focuses on the parts that matter when you're building or editing a model on the Code tab. If you've never used agent-based modeling before, the Concepts chapter is the right place to start.
