Hi, I am Jinyi (Bruce) Li ⟐
I'm a product builder
studying Cognitive Science
at the University of Michigan.
I'm building Hiu, an AI
game on the App Store,
and I run a small web studio
called Pop Up Limited.
Hi, I am Jinyi (Bruce) Li ®
I'm a product builder
studying Cognitive Science and
building AI products people use.
Hey, Just An Intro
I'm a Cognitive Science student at the University of Michigan, graduating in 2027. Outside class I build products. Right now that means Hiu, an AI game on the App Store, and I'm most interested in how people come to trust an AI character, or stop trusting it.
Bringing Ideas to Life
Everything here was used by real people. Two iOS apps I built on my own passed 20,000 downloads, a mystery game I ran as a PM reached 200 players in two weeks, and Hiu is on the App Store now.
Collaborate with Me
I'm applying to graduate programs for fall 2027. If you have questions about any of this work, my email is at the bottom of the page.
