What is Agent Builder?
Agent Builder turns a short description of your use case into a production-grade, call-ready voice AI agent — in 5 to 8 minutes. No prompt engineering, no guesswork. Just fill in a form and get a fully structured agent prompt, auto-selected voice, and a published version ready to make calls.How to Use It
Click + New Agent in the sidebar and choose Auto Build Agent to open the Agent Builder. The form has 3 steps:
Once submitted, your agent is production-ready in 5 to 8 minutes. You can navigate away — the agent will appear in your dashboard when ready.
Step 1 — Identity & Goal
There are two ways to provide context — and the more context you give, the better your agent will be.Upload a document
Upload a PDF, DOCX, TXT, or CSV — a call script, SOP, FAQ sheet, or any business document. The builder reads it and pre-fills the fields automatically.
Fill in manually
Fill in the fields yourself. Be as detailed as possible — specific goals, flows, and guardrails produce a far better agent than vague inputs.
You can also do both — upload a document and add extra details in the fields. More context always means a better agent.
Fields
| Field | Required | What to enter |
|---|---|---|
| Agent Name | ✅ | The name the agent introduces itself with. E.g. Saanvi |
| Industry | ✅ | Select from the list or choose “Other” to type your own |
| Agent Designation | ✅ | The agent’s role. E.g. Recruitment Specialist |
| Company Name | ✅ | The organisation the agent represents |
| Company Description | Optional | A short description of the company |
| Languages | ✅ | One or more languages the agent should speak. Set one as Primary |
| Gender | ✅ | Male or Female — used to auto-select the best matching voice |
| Tone | ✅ | Pick one or more: Warm & professional, Formal, Casual, Assertive, Empathetic |
| What Should This Call Achieve? | ✅ | The call goal in 1–2 sentences. E.g. Screen candidates and book a technical interview if they qualify |
Step 2 — Conversation
| Field | Required | What to enter |
|---|---|---|
| Agent Welcome Message | ✅ | The first thing the agent says when the call connects. Use {variable_name} for dynamic values |
| Guardrails | ✅ | Hard rules the agent must follow — topics to avoid, things it must never say, when to hand off to a human |
| Conversation Flow | ✅ | The steps the agent follows in order. Numbered steps work best. E.g. 1. Greet → 2. Ask about experience → 3. Qualify |
Step 3 — Closing
| Field | Required | What to enter |
|---|---|---|
| Closing Line | ✅ | The last message the agent says before disconnecting. E.g. Thanks for your time. We’ll follow up by email. |
| Hangup Prompt | Optional | Toggle on to give the agent a custom instruction for when to end the call — useful for complex call flows |
