Introducing Confetti — Build hardware from a single prompt
Confetti · Oct 2026 · 1:35 · AI-annotated · YC Fall 2026
One presenter-led screen recording walks the full pipeline, with a corner facecam and a dark caption pill riding over every panel while a badge names each step. Signature moves are slow zoom-ins into UI cards, badge-led step transitions, and a closing dissolve from 3D render to live desk footage of the finished robot.
