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.
