Modeler AI
Free + open source
An internal AI assistant inside FlexSim. Build, run, and discuss your model in chat with the model's context loaded.
PracSim Modeler AI puts a multi-provider AI chat panel inside FlexSim. Hook it up to your Anthropic, OpenAI, or other provider API key, and the assistant can build, run, and discuss your simulation directly, with the active model loaded as context. It is open source and BYOK (bring your own key): you choose the model, you pay the provider, and your conversations never touch PracSim's servers.
What you get
- Build, run, and discuss your model in chat without leaving FlexSim
- Work remotely: connect to your model and build it from another device, away from the computer it runs on
- Model context loaded automatically, so the assistant works against the active simulation
- BYOK: works with Anthropic Claude, OpenAI GPT, and other providers
- Your API key, your provider, your data. No PracSim relay.
- Open source. Free to use, free to extend or fork.
