Peng Zhu

Peng Zhu is the founder of Jiu-Jitsu AI, and a Brazilian jiu-jitsu enthusiast. What stayed with him was not the hard round. It was the week after class: a technique that had just started to make sense was already slipping away, and the notes were scattered across too many places to help on the mat. He built Jiu-Jitsu AI so a grappler can log a session in seconds, keep every technique in one private place, and see the game take shape. The name is the product. Jiu-jitsu is the training. The assistant helps you choose what to work on next from your own log. It does not replace your coach.
