Everything you need to integrate the AI Voice Tutor into your platform.

*New to the Voice Tutor?

Start with the Getting Started guide to embed a working tutor in under 30 minutes.

Overview

The Voice Tutor is delivered as a hosted embed. You generate a signed session token on your backend, load our iframe with that token, and we send session data back to you via webhooks. Your platform handles authentication, billing, and the student dashboard. We handle the tutoring — voice, whiteboard, AI, and validation.
