I recently spent some time to move my entire note-taking system away from Notion to Obsidian because the latter runs on Markdown files, which are text files. Why? Because AI runs on text.

And that is also the argument from Patrick Morgan. Your notes, your documented processes, your collected examples of what “good” looks like—if those live in plain text, AI can actually work with them. If they live in your head, or scattered across tools that don’t export, they’re invisible.

There’s a difference between having a fleeting conversation and collaborating on an asset you both work on. When your thinking lives in plain text — especially Markdown — it becomes legible not just to you, but to an AI that can read across hundreds of files, notice patterns, and act at scale.

I like that he frames this as scaffolding rather than some elaborate knowledge management system. He’s honest about the PKM fatigue most of us share:

Personal knowledge management is far from a new concept. Honestly, it’s a topic I started to ignore because too many people were trying to sell me on yet another “life changing” system. Even when I tried to jump through the hoops, it was all just too much for me for too little return. But now that’s changed. With AI, the value is much greater and the barrier to entry much lower. I don’t need an elaborate system. I just need to get my thinking in text so I can share it with my AI.

This is the part that matters for designers. We externalize visual thinking all the time—moodboards, style tiles, component libraries. But we rarely externalize the reasoning behind those decisions in a format that’s portable and machine-readable. Why did we choose that pattern? What were we reacting against? What does “good” look like for this particular problem?

Morgan’s practical recommendation is dead simple: three markdown files. One for process, one for taste, one for raw thinking. That’s it.

This is how your private thinking becomes shared context.

The designers who start doing this now will have documented judgment that AI can actually use.
