I made an HN clone that lists only Substacks posted here. - Why? Over the years, I've discovered some great blogs here, so I thought it would be nice to have a filter for them. - Why only Substacks then and not blogs more generally? Because it's easy to query for "substack.com" in the public HN Algolia API (see below). Plus, hnblogs was already taken :) - What about substacks on custom domains then? At the bottom of the page there is a form to submit a custom domain. The site attempts to auto-validate that it is a Substack. If that fails, it is marked for manual review (which I'll do every once in a while). Approved ones will be included in the results. - How? I use HN's Algolia API to fetch substack stories by searching for "substack.com" in the url.

Transform hand-drawn doodles into animated memes.

I like doodling, and I like character animation. I made a little tool that can animate your hand drawn characters and put them into an animated meme. It's free, there's no login needed, and it uses an animation pipeline (not generative AI) to create the outputs. Works on desktop and mobile. If you give it a try, I'd love to hear your feedback. Thanks!
