dotey: a one-line prompt iterated into a product intro video rendered in JS canvas
dotey · x · 2026-09-27
dotey shares that his much-discussed product intro video started from a very simple prompt: based on the app's prototype pages and icons, use JS to render a canvas directly and generate a fun, memorable product intro video. The rest came from gradual iteration; the polished prompt circulating was only written afterward by having AI summarize it.
