2.3.5. AI Suggestions

You can use Connext AI to get suggestions about how to build or modify your system model. AI-generated suggestions display in the chat panel where you can review and apply the generated code.

There are three ways to get AI-generated suggestions:

  • Use the Create with AI option when creating a new project. For details, see Create with AI.

  • In the chat panel, request modifications specific to the open project’s model. For example, you could request to add a new domain to an existing domain library.

  • In the tree panel and Structured View, right-click any item and select the AI command from the context menu. For example, right-click a DomainParticipant and select AI > Modify this to get assistance fine-tuning the selected element using a natural language prompt.

After a suggestion is generated in the chat panel, the code is automatically validated to confirm the XML is properly formatted. If you want to use the suggestion, click Apply to System Designer Project to integrate the suggested code into the current model.

Note

Although the code is validated, it may still contain errors. Review and test all suggested code before deploying in production.

After applying an AI-generated suggestion in your project, a System Designer checkpoint is created automatically. A checkpoint is a snapshot of the open project that you can restore to undo an applied AI suggestion. For details, see Creating a Checkpoint.
