Five steps to go live

Each step takes just a few minutes. No code required to get started.

Step 01Agents → Create New Agent

Create your first agent

From the left sidebar, click Agents, then hit the Create New Agent button at the top right. You'll be guided through a two-step wizard.

✓ Select your industry (e.g. Healthcare, Hospitality, Retail, or General)
✓ Give your agent a clear, descriptive name — e.g. SupportAgent_UK
✓ Click Create Agent to save and continue to configuration

Tip: Use a naming convention that reflects the agent's role and environment — e.g. BookingAgent_Prod or SpaAgent_Test. This helps as you scale to multiple agents.

Step 02Agent Configuration

Write your system prompt

The system prompt is the brain of your agent. It defines personality, tone, scope, and how it should handle calls. A well-crafted prompt is the single biggest factor in agent quality.

✓ Define the agent's role, business name, and persona
✓ Specify what topics to handle — and what to escalate
✓ Include verification steps if callers need to be authenticated
✓ Set the expected tone — formal, friendly, professional

Tip:Start your prompt with "You are…" and write as if briefing a new employee. Include example phrasings for common caller intents to keep responses natural.

Tools & Integrations

Step 03Tools Configuration

Connect tools & actions

Tools let your agent take real action during calls — checking availability, creating bookings, fetching data from your systems via HTTP. You can create new tools or link existing ones.

✓ Enter a tool name (e.g. check_availability)
✓ Add a description so the AI knows when to invoke it
✓ Set the HTTP endpoint URL and method in the JSON config
✓ Define the parameters schema the tool accepts
✓ Click Create Tool and it appears in Active Tools

Tip: If you already have tools from other agents, use Link Existing to reuse them without duplicating configuration.

Step 04Test Agent Tab

Test before going live

Use the built-in browser test to speak directly with your agent. Allow microphone access, hold a real conversation, and review the transcript to verify accuracy.

✓ Navigate to the Test Agent tab in the wizard
✓ Click Test Agent and allow microphone access
✓ Speak naturally — test common caller intents and edge cases
✓ Review the call transcript for accuracy and tone
✓ Click End Test Call, then refine the prompt if needed

Tip: Test at least 5–10 real scenarios including edge cases — angry callers, unclear requests, and out-of-scope questions — before assigning a production phone number.

Assign Phone Number

Step 05Phone Numbers Tab

Assign a phone number & go live

The final step links a real phone number to your agent. Once assigned, any call to that number is automatically handled by your AI agent, 24/7.

✓ Navigate to the Phone Numbers tab
✓ Select an available number from the dropdown
✓ Optionally add a label (e.g. Support Line)
✓ Click Add Phone Number — the webhook is auto-configured
✓ Click Update Agent to save. Your agent is now live!

Tip: You can assign multiple numbers to a single agent. Check your Phone Numbers section in the sidebar to manage all numbers in one place.
