I made a tool to help me search images for drawing or design, it's free and open source and you might wanna try it. "Pictogrep" It has been very useful, almost every day for me, since the original Pinterest search is not great. You can also "follow" Pinterest folders and it downloads all the images automatically, like web-scrapping. It uses a local offline tiny model to embed the images, so search is instant and navigation is always super smooth. When you open an image, you can see its related images. link below.
