AI language buddy in kids' games

What is your company going to make? Please describe your product and what it does or will do.

We build an AI companion that interacts with children inside games like Minecraft. It chats and plays with them while helping them learn a new language in a natural, playful way. Instead of kids just spending hours gaming, parents can turn that time into learning time with our AI that fits inside the games kids already love.

Where do you live now, and where would the company be based after YC?

We live in San Francisco, CA, and we plan to keep the company based here after YC.

Explain your decision regarding location.

San Francisco is where the team lives and works. It's the best place for us to find talent, connect with early customers, and stay close to the gaming and AI communities relevant to our product.
