How it works: you type "goggles under $15 that ship from the US", Vesim checks every store it indexes, and lands on the cheapest one that fits: $6.93.
The same search, the way it goes today and the way it goes here.
Any product page from any shop, or a photo. We find every other seller of the same thing, right here.
The photo is fingerprinted on your device. Only 64 bits are sent, never the image.

Two listings, two names, two prices. Watch each photo turn into its fingerprint, and the two fingerprints line up.
Every comparison site matches on words. Edit these two real titles and watch the words drift while the photos stay identical.
Five steps, running in your browser on a real listing. Scroll and watch the photo become its fingerprint.
Every one of 74,691 photo pairs in the index, by how different they are. Drag the line and see what it would merge.
Your sentence becomes requirements, each one snapping into place. Anything we can't check is shown, never quietly dropped.
Every candidate on one line. The cheapest fails something you asked for, so the light moves to the one that fits. Switch a requirement off and watch it move.
Three things a shopping search doesn't do, and we do on every answer.
Sellers rename the same product a hundred ways. They almost never change the photo, so that is what we compare.
Instead: Shopping search matches the words and the product codes, so renamed copies look like different things.
The cheapest listing is often the wrong one: wrong country, over budget. We gate on what you asked for, then sort by price.
Instead: Shopping search sorts by relevance and ads, and leaves you to check each requirement yourself.
If nothing meets every requirement, you get a clear no and what came closest, instead of a page of near misses.
Instead: Shopping search always shows something, close or not, so a near miss looks like an answer.
Every bright point is a product in the index today, placed by what it looks like. The faint field is room for the catalogues on the way. Hover a cluster.

Vesim is free. Plus is for people who never want to check twice.
Watch anything. When the price drops, or a cheaper seller of the same thing appears, we tell you. Price history on every product, and the extension checks every page you open.
The honest comparison is the only thing we sell. These are the rules, and the questions people ask first.
Vesim matches the product photograph rather than the barcode, brand or title. Resellers do not photograph their own stock — they upload the supplier's media pack unchanged — so the identical image file appears on every listing of the same object. Each photograph is reduced to a 64-bit perceptual hash and listings within 10 bits of Hamming distance are treated as the same object. Measured on 60 real product photographs: 98% recall with zero false matches across 1,762 true negative pairs.
Most goods sold online have no GTIN or barcode, particularly unbranded goods sold by many resellers. Those are exactly the products with the largest price spreads, so barcode matching fails precisely where comparison would be most valuable.
The lowest price among sellers that satisfy every measurable constraint you gave. It is distinct from 'cheapest anywhere', which may be lower but violates one of them — for example by shipping from a country you excluded. Vesim shows both, names the reason the cheaper one does not qualify, and will return nothing at all rather than hand back a near-miss.
No. Vesim holds no stock and handles no checkout. Every link goes to the seller. Some outbound links earn an affiliate commission, which is disclosed on every page carrying them and never affects the order results appear in.
Vesim is built to search millions of products, and it is early days: one catalogue is connected today, with 376 products from 387 listings, fingerprinted and compared across 74,691 pairs. Comparison across different stores, the thing the product is for, arrives as each network connects. Adapters for eBay, Amazon, Walmart and AliExpress are written and tested, and are waiting on credentials rather than on engineering.
No connected source returns delivery dates, so arrival constraints are reported as 'not measured' rather than estimated. Discount codes are not available. Price history does not exist yet, because it cannot be backfilled and the first daily snapshot has not run. And a matching photograph is strong evidence of the same object but is not proof of an identical pack size or revision, which is why both images are always shown.
Only the fingerprint: 64 bits, computed in your browser. The photo itself is never uploaded when you drop or paste an image. When you paste a link, our server reads that public page to find its product photo, then the same 64-bit fingerprint is compared against the index.
Describe it. We’ll show every price, which one fits, and tell you when nothing does.
It’s early days. Today we search one catalogue of 376 products, and the matching is measured and real. More stores connect every week, and every one makes every answer wider. The live numbers →
