Go to heysonara.com and create an account using your email, Google, or GitHub. You’ll receive a $5 welcome credit on the free plan - enough to test your first agent.

After signing in, you’ll land on the dashboard. Your default workspace is created automatically. You can rename it or create additional workspaces later under Workspace Settings.

Create an agent

Navigate to Agents in the sidebar and click Create Agent. Give your agent a name and description, then click Create.You’ll be taken to the agent configuration page where you can customize everything - instructions, voice, language model, and more.

Write instructions

In the Instructions tab, write a system prompt that tells your agent how to behave. For example:
You are a friendly customer support agent for Acme Corp.
Help customers with order tracking, returns, and general questions.
Be concise, helpful, and always confirm before taking any action.
Optionally, set a welcome message that plays when a call starts.

Choose a voice

Go to the Voice tab and select a voice provider and voice. You can preview voices before selecting one. Adjust the speed if needed.

Test your agent

Click the Test button in the top-right corner to start a live voice conversation with your agent. Speak naturally - the agent will respond in real time.
