About Lamina Labs

Lamina Labs is building infrastructure for near-real-time structured video generation. Most AI video is built for cinematic clips. Lamina is built for useful videos that teach and explain. Our first product, Simi, turns prompts, documents, and AI answers into whiteboard-style teaching videos in seconds. Our goal is to make video the default interface for AI communication.
