GenUI

14 Feb 2026

Where was I?

Let’s just say that a fair bit has happened since 2019 and the The Monument Valley login problem. Moved on from ustwo, opened and closed Dersu, joined and was laid off from tado and 2 years too late I finally joined VGV, one of the best Flutter teams in the world.

Which brings us to GenUI.

What is GenUI?

GenUI is LLMs rendering user interfaces at run time.

Think complete interface personalization provided by the LLM understanding (or finding out) who you are and what you want to achieve. In real time.

There is a lot to talk about GenUI, but for now I’m not going to put it in writing because in all honesty it’ll probably be obsolete by the end of week. It is moving that fast.

So instead I’m going to use this page as a resource centre for the time being. I promise* I’ll put down my thoughts at one point. In fact, I’m doing a couple of talks about GenUI, I’m hoping they’ll be recorded and publicly shared, I’ll update this page when available.

And if you want to talk GenUI please reach out! You can find my email and Linkedin profile on my main page.

• VGV’s intro to GenUI.
• Google Research: Generative UI: A rich, custom, visual interactive user experience for any prompt.
• Google’s Flutter GenUI SDK repository, which includes sample apps.
• A2UI.org, home page of Google’s open protocol for agent driven interfaces. Loads of down to earth documentation, including an intro to the core concepts.
• Thesys’ Generative UI: What It Is and Why It Matters and How to Build Generative UI Applications. These are long, but well written deep dives.

* I can’t promise, really.
