About this video

I think voice is going to become the default way we talk to computers.

So I built Tabi, an AI language coach that teaches you Japanese through live conversation with Gemini 3.8 Live, and in this tutorial I show you exactly how I built it in 6 steps, from exploring the idea with AI to launching it on the web.

You can follow along to build a live voice language app for whatever country you're visiting next.
