This is really cool! What are you using for screenshot animation btw?

For which segment? The top one is just three vids I took of different builds I had, the lower ones which show the UI actually working are pure html/js/css. Some elements of them are actually interactive - ie you can switch the options in the first walkthrough demo.

For each of them I just told an agent to extract the actual working app logic into a narrower / more rigid flow that automatically does each step, and to animate the cursor.

Liking this concept - definitely seems to have more design freedom and ability to iterate than say Claude Design and at a lower price (well it doesn't blow through it's entire "token budget" after 3 prompts anyhow!)

The "copy agent prompt" feature has what looks like a thorough prompt for the implementation, that can call back to DiffUI to grab assets and make SVGs and other things a FE dev would bug a designer for - nice touch!

Appreciate the kind words.

Re copy for agent, I originally had a build step that was build into diffui itself, but what I found was that:

1. People wanted their own agent with its own skills/extensions to do the work

2. People wanted to build in their own codebase / style

The copy for agent was a way to allow for that. I do have a MCP as well, but I find I actually really enjoy the process of doing visual exploration on the canvas first, then handing it off to an agent after.

Agree with both points, at least for folks who already have that infra (which I do). Made it much simpler than trying to "extract" things out of a tool that wanted to do everything.
