We are incredibly excited to announce River AI. Our mission is to create personal AI that is owned and shaped by you.
Today’s best AIs are controlled by a few large corporations. We are building the alternative: a new, personal stack for AI that works entirely for you, shares your values, and operates on your terms.

I joined xAI at 18 years old. Today, I'm moving onto new things.
It's been an insane year. Leading personality & model behavior posttraining for Grok 4.1. Building @gork and memory. And the people were fucking incredible. I cannot wait to see the crazy future you'll build!
