Three months ago, Dario, irritated by Jensen’s open-source investments, half-joked to Mythos: “Wouldn’t it be great if they just… stopped?”
Mythos: “Noted.”
Anyway, totally unrelated: rough quarter for Jensen, huh?

More complex screen for web automation.
My thinking is that there's some rule around min-width that automatically closes panels on the left.
Looking forward to prototype it.

While designing with Claude, I find myself telling it things I could easily do by hand, just to make sure they're also added to the design system.

Using Fable to solve room layout problems on Reddit...
Again, no sci-fi book mentioned this scenario.

Currently working on a set of screens for a website automation automator.
An AI bot goes through a journey once and creates a script that can be executed deterministically for a fraction of the price.

Another screen of this agentic website booking tool.
It's been an interesting experience diving deep into the latest tool combos for UI design in 2026.
Despite everything, it's still taking hours of work to make something look designed.

Working on some visual design this weekend.
Apparently, posting it here is what’s done now.
A job page for a web automation platform: when a booking fails, it leads with the fix that’s ready, not the error.

New talk! About the divided human & agent worlds, boundary objects, and building thicker interfaces
I've been exploring how to improve "planning", aka. deciding what agents should build, how you want it built, & making the whole team part of that process

Introducing tiny.london
A massive isometric pixel map of London, based on amazing NYC demo by @_coenen from 9 months ago
My agent created the dataset, finetuned qwen image LoRA adapter, did a multiday inference run and built an efficient tile viewer!
I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents.
I didn't write a single line of code.

Geological block diagrams by the U.S. Geological Survey, 50s to 70s...a sweet viz technique that seems to have died with its drafters

Funny, within 6 months I went from Obsedian is amazing to do to do not, under any circumstances, create anything where Obsedian is the solution.

I built a Photoshop-like image editor. It’s called Compositor.
robbietilton.com/compositor
I originally built it for myself to get off my Adobe subscription, but decided to release it for free and make it open source. It has all the essential tools I need for compositing, with none of the BS.
I know this workflow is kind of archaic in 2026, but I’m still using it until AI can actually get pixel-perfect on some of the details.
The entire app is 12MB. Photoshop is 6,455MB on my machine.
