   I made a new AI colorizer▲472

   Hi HN, I’m Emil, the maker behind Palette. I’ve been tinkering with AI and colorization for about five years. This is my latest colorization model. It’s a text-based AI colorizer, so you can edit the colorizations with natural language. To make it easier to use, I also automatically create captions and generate filters. Let me know what you think. You can see some of my results on my reddit page: https://www.reddit.com/user/emilwallner/?sort=top
