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 DiffLens (https://www.difflens.com/) initially just for myself. It's a diff tool that uses abstract syntax trees to make the diff more review-able. It's free for anyone to use too. I use it every day to review my diffs. If anyone works on Typescript, Javascript, HTML and/or CSS, do check it out!
