Let's say.... 10 shot with Claude Code :) Initial app, then hand refined, Claude Code again...back and forth. Spend my morning doing it and it was fun. Very simple so far, want to clean it up and add more meaningful features.

EDIT: Also, turns out the in-browser Editor landscape got GOOD the last few years apparently. It's really just plug and play. I remember 5 years I tried to do this and it was painful.
