Built for this workflow

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

Design multi-step survey scripts with Burst nodes, Likert scales, yes/no, and open-ended questions.

Skip irrelevant questions based on previous answers using IfElse nodes for a natural experience.

Push every answer to your database or analytics platform in real time via webhook.

Configure the LLM and persona to ask questions naturally, not like a robotic form readout.

If the respondent is busy, schedule a callback time and trigger the call automatically.

Run the same survey in multiple languages by configuring TTS and STT providers per flow.

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.
