Built for this workflow

Everything you need to design, test, and deploy your voice agent, visually.

Design structured outreach scripts with opening, qualification questions, and a clear CTA.

Route interested prospects to a rep, and disinterested ones to a follow-up sequence via IfElse.

Push prospect data to your CRM automatically via webhook nodes mid-call.

Connect engaged prospects directly to a sales rep via SIP Transfer without losing momentum.

Let prospects choose a callback time and book it automatically via webhook.

Describe your ideal lead gen script and the AI builds the full outreach conversation.

Spin it up. Call it. Refine until it’s right.

Describe the voice agent you want, like 'Build a pitch practice bot', and the AI creates the full conversation flow instantly.

Drag, drop, and connect nodes to reshape the conversation flow exactly how you want it.

Describe what you want to change in plain language and watch the agent update in real time.

Talk to your agent right inside the builder - no deployment needed.

When the agent says something off, click on that message in the conversation panel to correct it.

When your agent is ready, deploy it with a single click. No extra tools or setup required.

Generate a share link and send it to anyone. They can test your agent directly on voiceblox.ai, no app install needed.
