The AI Interface Company

You draw. AI draws back on the same space. We build the interfaces and the machine that ships them.

Interfaces

Two products. One paradigm.

Sketchbook

Superpencil

Visual-in, visual-out.

An agent-native visual thinking app. You draw, annotate, and sketch on an infinite canvas — AI agents respond visually in the same space. No prompts. No text boxes. The pencil is the interface.

Founders

Built from the first line of code.

Chief Executive

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). Co-founded Superworld (ST World) with Elijah — 20,000 users, featured on a16z market map. Built Superpencil in 6 months, Superdirector in 6 weeks.

Chief Technology

Elijah Mansur

Elijah has been shipping products since he could code. He and Bell co-founded Superworld (ST World) — shipped it on Steam, grew it to 20,000 users, featured on the a16z market map. Then he went and did it again — co-founded Dental Agent, built a camera vision system for dental procedures that's installed in 7 operatories (Z Fellows '25, raised pre-seed). Built DuoDate on the side (2K users). Published in IEEE. Three startups by 23.
