The Canvas

Learn to build powerful AI conversations using the Canvas in your NLX workspace

What's the Canvas?

The Canvas is a visual and interactive design tool for building your conversation flows. Each conversation flow has its own Canvas to build all steps and possible paths. Every Canvas begins with a non-editable Start node from which your conversation will progress.

Analyze, Validation, and Test view

View modes from the Canvas toolbar

Activate one or more modes simultaneously from your Canvas toolbar:

You can continue to modify and build with your flow while these modes are activated. Simplify select the Canvas to adjust the flow and save changes.
