🎨 Build Your First Agent

Once the app is running and your API keys are configured, here’s how to build a simple voice agent.

​
Manual build

1

Add an Agent node

Drag Agent from the sidebar onto the canvas. This is the central node that orchestrates your voice agent — configure the agent name, persona, and language here.
2

Add component nodes

Drag an LLM, TTS, and STT node onto the canvas. Connect each one to the Agent node — they auto-route to the correct handle.
3

Configure the Agent

Click the Agent node and fill in the Persona (system prompt) field — e.g., “You are a friendly customer support agent.”
4

Build the conversation flow

Add a Start node and connect it to the Agent node’s output. Then add a Burst node, then an End node. Chain them: Start → Burst → End.
5

Set the opening line

Click the Start node and set the Command to your opening line (e.g., Hello! How can I help you today?). Enable Is Literal to speak it verbatim instead of generating it.
6

Test it

Click Test in the top bar, then Start Session. Allow microphone access when prompted and start talking to your agent.

​
Or use the AI generator

Instead of building manually, describe your agent in plain language:
  1. Click the AI button in the toolbar
  2. Type something like: Build a customer support agent with a greeting, a triage question, and two branches: billing and technical support
  3. The AI generates the full flow and applies it to the canvas automatically
