Done

BDK Comparo

I needed to compare two folders. So I built a Mac app.

The Story

I had a bunch of video files backed up in two different places and needed to know which ones I could safely delete. I described what I needed to Claude, and twenty minutes later I had a working SwiftUI application that showed me exactly which files existed in both locations, which were unique to each, and what I could safely remove.

Twenty minutes. An actual application with a UI, drag-and-drop support, and a clear visual diff.

I used it, deleted what I needed to delete, and freed up about 200GB of space. Problem solved.

This is the project I think about when people ask me why a lawyer cares about AI tools. Because the ability to see a need and build a solution — right now, in the moment — changes how you think about problems. It changed how I think about problems. And I believe it can change how the legal profession thinks about problems too.

Built with Claude

This was the simplest collaboration: I described what I wanted, Claude built it, I tested it, asked for a couple of adjustments, and it was done. The whole thing took less time than it would have taken me to manually compare the folders.
