About Cantina

Cantina, founded by Sean Parker, is an invite-only playground that puts AI into the hands of creators and allows them to bring any idea to life as a social bot that can be experienced with friends directly in the Cantina and also shared across the internet.

It's the first place where people can create, explore, and chat live with personality-driven AI bots together with their friends. People can choose from Cantina’s collection of thousands of unique bots, or build awesome AI bots from scratch with just a few prompts.

While a lot of AI focuses on improving productivity and efficiency, we believe our AI bots will drive the future of entertainment on the internet and we’re excited about the creative potential they will unlock for everyone.
