Speech is a muscle, and Rizz AI is the gym. Most people speak less than 10 min a day, but with our voice-to-voice AI conversations, practice your social skills and speaking, get tailored feedback on where you can improve, and build your confidence speaking.

Rizz.AI is an open-source AI-voice app that lets you practice everyday social interactions. Pick a character, select a scenario (dating, negotiating, etc), and get a custom score with feedback on how to improve. Bring your A game or prepare to get roasted.
