Design Tools Are Going Headless: Tom Krcha

Tom Krcha founded Pencil.dev after years inside the design tooling cycle, from Flash evangelism to creating Adobe XD, which gives him a rare view of where AI design tools are actually heading.

This conversation covers why agents are best at the first 80%, why designers still need the last 20%, what a headless design tool means, how Pencil is building for swarms of AI designers, and why taste comes from still putting your hands in the work.
