Voice Agent Builder
Build a voice agent by creating a new agent at https://app.lemuai.com/workflow and talking through the setup with the AI Copilot.
Creating a new agent opens the workflow canvas with a default flow already scaffolded — a Global node, a Start Call node, a main conversation node, and an End Call node — plus an AI Copilot panel on the right. The Copilot adds extra steps when your use case needs them (for example, finding a slot and then confirming the booking).
Talk (or type) through what you're building — the Copilot has a live call connection while you describe your use case, and fills in the canvas nodes and prompts as you speak. Be as specific as you like: deadlines, offers, what to say when a customer refuses, how firm or friendly the agent should be. Everything you ask for is written into the agent as you said it. The only exceptions are abusive language, made-up threats and harassment, which Lemu agents never use. See AI Copilot for more on what it can do beyond initial setup.
Once the starting flow is in place, you can:
- Edit any node's prompt directly on the canvas to fit your use case
- Test the agent with a Call right from the builder
- Save your changes as a draft, or Publish when it's ready to take real traffic
