Agents can make one-off apps, but they’re usually toys. I show how we might bring malleability and composability to the kind of deep interfaces that experts live in all day—demonstrated in a writing environment, but applicable to all serious software. Little serious reading software exists, so I propose and demonstrate a new kind of malleable digital reading environment focused on expert use.

But malleable interfaces aren’t enough. Historically, inventing interfaces has required imaginative design skill, deep domain insight, and fluent programming. Few have all three, but programming is the only skill that can produce working software on its own—so interface invention culture is dominated by programmers. I share early reports of how coding agents are changing that, and what it might mean for the people and institutions inventing interfaces today.
