Hear from every customer after launch, not just the loudest ones. An AI agent calls users, collects structured feedback, and logs it automatically.

Built for this workflow

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

Design structured feedback interviews with satisfaction scores, open-ended questions, and feature ratings.

Probe unhappy customers deeper and fast-track promoters to a referral ask using IfElse nodes.

Push all responses to your product analytics tool, CRM, or spreadsheet in real time.

Configure the LLM persona to sound like a curious PM, warm, conversational, not a survey bot.

Route highly engaged or critical customers to a product manager for a deeper interview via SIP.

Launch feedback calls automatically via webhook after trial end, first purchase, or feature adoption.

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.
