What does the Nodes AI Agent do?
The AI Agent, at the top right, builds the flow for you: you describe what you need and it creates the nodes, connects them, fills in prompts, styles, lists and settings, and frames the result on the canvas. If you select nodes before writing to it, it takes them as a reference.
The Agent doesn't run anything: when it's done it tells you what's missing — for example, uploading your photo — and you decide when to generate. Using it costs no tokens and it's on every plan; the nodes it builds charge when you run them. Its history is saved per project in this browser.
