Open any flow in the builder and click the AI Assistant icon (bottom left of the canvas) to get help with that one flow, the same AI Assistant available in every other project type, scoped here to whichever flow you currently have open.
Chat mode
Ask questions about the flow's current structure, what happens if a user sends X, why a branch isn't wired the way you expected, and get an explanation back. Chat mode only answers, it never changes your flow.
Generate mode
Describe what you want in plain language, e.g. "add a step that asks for an email address and validates it looks real," and the assistant proposes a complete replacement for everything in the flow except its trigger block, which is never touched. Review the summary of what changed, undo is always available if it's not what you meant.
This requires the separately-paid AI Assistant add-on, see "What's the AI Assistant add-on?" in Account & Billing for what's included and how usage is measured.
Tip: Generate mode works one flow at a time, exactly like Discord Bot's per-command AI generation, if your bot has several flows, open the one you want changed before generating.
