Amazon, Temu, and AliExpress already have visual search. Desktop just hides it.

I shop on a laptop. A lamp on Amazon that costs too much. A jacket in a listing photo. Something I saw on eBay and wanted to check on Temu. On my phone, that is a camera tap. On desktop, the camera icon is mostly missing. So I built SameSame , a browser extension I still use every day. It does not send your photo to a third-party reverse-image API. It opens the visual search each store already runs - the same one their mobile apps and some out-of-stock flows use - from the page you are already on. The desktop gap Visual product search is not new. Amazon Lens, Temu camera search, AliExpress image search: they work because they search inside that store's catalog. That is different from Google Lens, which searches the open web and often returns a mix of blogs, pins, and shopping links. The catch is where those tools live. Amazon's image search is a first-class feature in the shopping app. On amazon.com in a browser, it is easy to miss or simply not there, depending on the page. Temu and AliExpress follow the same pattern: obvious on mobile, buried or absent on desktop. If you want to search by image from a laptop, the usual advice is: save the image, open the store app or a reverse-image site, upload, then repeat for the next store. That is a lot of friction for something the store already knows how to do. The searches were already there I did not invent a new matcher. Amazon, Temu, and AliExpress already run visual search against their own catalogs. On mobile that is the camera in the search bar. The same capability shows up in other places, including some out-of-stock and similar-items flows on the web. When a listing is unavailable, you have sometimes seen visually close alternatives. That is not a coincidence. The catalog search is already wired up. Desktop shopping just does not put a camera on every page. Those endpoints are not a public developer API you sign up for. They are the stores' own visual search, used by their apps and a handful of desktop pages, mostl
