> ZaiSpace is a social app built around shared experiences. > Create Your Zai Your Zai is your ideal self. A digital being you hatch, name, and shape into whoever you wish you could be. It lives in ZaiSpace, representing you in ways a profile photo never could. > Go on Hangouts Your Zai meets other Zais and they go on adventures together. Each hangout becomes a story. Sometimes funny, sometimes surprisingly heartfelt. You just pick a topic and see what unfolds. > From Stories to Real Conversations After each hangout, the story drops right into a chat between you and the other person. No need for an icebreaker. You already have the best one. > Memories That Grow With You Every hangout leaves a trace. Over time, your Zai builds a collection of shared moments and a quiet reminder of the people you've met along the way. > We're a small team at Stanford who believe friendships start with having shared experiences, not scrolling past each other. Come hang out with us. > Questions? zaisland2024@gmail.com
