Otis turns AI chat into 3D

This is a smart UI thesis, but the real win is probably better navigation and project sensemaking, not a dramatic memory breakthrough.

• –3D scenes give conversations a mental map, which is useful when prompts, code, and research notes sprawl across a long project.
• –The tradeoff is classic 3D friction: occlusion, camera control, and spatial ambiguity can make finding things harder if the interaction model is clunky.
• –The stack choice makes this an interface innovation on top of OpenAI, not a new model or infrastructure story.
• –The biggest question is whether Otis pairs the spatial metaphor with search, tags, and persistence; without those, it risks feeling like a polished demo.
• –The 400% retention claim should be read as a hypothesis, not a proven result.
