Why This Matters

This article highlights the enduring relevance of plain text and ASCII-based tools in the tech industry, emphasizing their simplicity, portability, and evolving role in modern workflows including AI integration. It underscores how constraints in design can foster creativity and efficiency, which is increasingly vital as computing capabilities expand.

Key Takeaways

There’s a category of “plain text” or “ASCII” diagramming and UI design tools:

Mockdown – works immediately on the web, even on mobile

Wiretext – works on the web, but desktop only

Monodraw – a Mac app

I believe these are used by people who prefer intentionally limited visual choices, for low-key diagramming to put in source code, and – increasingly – as an entry point to gen AI.

They’re so interesting from the standpoint of this blog:

Fun to see a contemporary take on something that peaked between 1970s–1980s – you can look up TUIs and Turbo Vision if you want – but (just like Mario the other day) now with modern sensibilities, performance, web access, mouse and trackpad affordances, and so on.

It’s interesting simply as an exercise in constraint. I believe constraint practice will become more and more important as computers become more and more capable. It’s already useful to constrain yourself in order to make things easier for you. With the rise of AI, self-constraint will become important to make things harder, as well.

There is a certain power and longevity of monospace plain text that’s worth celebrating – not just because the file format is portable, but because text editing as interface is so well-known and potent.

Also, ASCII spray in Mockdown is just really fun:
