Are you referring to something like https://www.algolia.com/doc/guides/solutions/ecommerce/visual-image-search/tutorials/search-by-image/ or https://www.algolia.com/doc/guides/solutions/ecommerce/visual-image-search/ ?

Yes, I have looked at this document. However, it’s quite difficult for people like me who don’t know how to code

As is, we don’t have anything in the out-of-box plugin and templates that we ship with for this specific topic. So we don’t have the code worked out on our end either to implement the topic. Even then, it would be needing customizations to meet per-site demands.
