Hello World - Building ThreeTone

Welcome to our first blog post! We're excited to share our journey building ThreeTone, a platform for creating and deploying voice AI agents.

What is ThreeTone?

ThreeTone is a complete platform for voice AI:

  1. Build - Create agents with natural language prompts
  2. Test - Real-time voice testing in the browser
  3. Deploy - One-click deployment to phone numbers worldwide
// Example: Creating an agent with our SDK
const agent = await threetone.agents.create({
  name: "Sarah - Customer Support",
  voice: "nova",
  systemPrompt: "You are a helpful customer support agent...",
});

// Assign a phone number
await agent.assignPhoneNumber({
  country: "US",
  areaCode: "415",
});

What's Next?

We're just getting started. In the coming weeks, we'll share:
