Charis Zhang, Oliver Johansson, and Tobias Worledge, three Berkeley CS undergraduates, have co-founded RIZZ!, an AI-dating app that uses AI to generate witty and charming messages. The app, which was featured on “The Today Show,” has helped users drastically reduce the time between chatting online and meeting in person. “Traditionally it might take you a week, but with RIZZ!, it might take two to three days to get a date,” said Zhang.
