Leonardo Demurtas
Product designer. Every product now has two users — humans and agents. I design for both.
What I do
I'm a product designer. My work right now is about one shift: products don't have only human users anymore. Agents read pages, click buttons, and call actions too.
I write about what that means for design systems, and I build small experiments to test the ideas instead of only writing about them. This page is the home for both.
Now: writing weekly on LeLines and turning the essays into working demos.
Experiments
- Run dashboard live
A dashboard that turns my Garmin running data into one readable page.
Writing
One essay a week on LeLines, my Substack. Start with these:
UX has a second user now
Designing for the agent that now operates products on the human's behalf
Can vs. may: the gap in every design system
The question nobody has written into their design system yet: who decides what the agent is allowed to do
The four stages of working with AI
Chatbox, projects, agents, loop, and the one setup move most designers should make next
