Founder & CEO

Bell Chen

Bell prefers slower LLMs — he can't read as fast as they output. When he tries to describe a design idea in text, the idea dies in translation. So he started drawing things out on paper and photographing them as input. That's visual-in visual-out — he was doing it by hand before building it into a product. Coding since 14. Image generation paper at 18 (IEEE oral). Built Superworld (ST World) — 20,000 users, featured on a16z market map. Built Superpencil in 6 months, Superdirector in 6 weeks.
