Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.

I built a Chrome extension to be able to use spaced repetitions for chess puzzles/exercises that I found online. Used it for a couple years and gained at least 200 Elo rating with it :)

Recently I built a public facing website for that, if anybody is curious: chess.braimax.com
