This is an implementation¹ as a follow-up to a previous post² about preventing posting dupes on Instagram, through a simple ML model.

For now, you can upload an image, and it'll give the top k (5, at the moment), images that your image is similar to.

This approach makes it so that I can use it, which is the main priority, and also lets others have fun with it. Usually if I'm editing photos, I have access to the internet as well. I have thought of an offline- and mobily-only version of how it could be built.
