Hyperclay: a way to package up HTML files as portable, editable apps that contain their own editable UI. I'm using these simple apps to plan, edit emails, write blog posts, and a lot more. I edit them on my mac and they sync to the web live.

It feels like being able to design my own document format on the fly and display it however I want. It's making it painfully obvious how many editable primitives the web is missing, however.
