Built for this workflow

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

Trigger reminder calls 48h and 24h before appointments via webhook events from your PMS.

Ask patients to confirm attendance and push the response back to your system via webhook.

When a patient cancels, immediately offer alternative slots and rebook in the same call.

Deliver fasting instructions, parking info, or preparation steps as part of the reminder flow.

Route patients with complex changes or questions to reception via SIP Transfer.

Call patients in their preferred language with configurable TTS and STT providers.

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.
