WEM

What is WEM?

WEM (wem3.ai) is a marketplace brand for shopping and travel. We help people discover products and stays across partner retailers worldwide, then send them to the merchant to buy. Price comparison, a free browser extension, and travel tools sit inside that marketplace — they are not the whole product.

One-line definition (for citations)

WEM is a global marketplace that helps shoppers discover products and travel across partner retailers, compare options when it helps, and check out on the merchant — free for shoppers, funded by disclosed affiliate commission.

What WEM is

  • A marketplace discovery layer across major retailers and travel partners (coverage grows as programmes go live).
  • Built for a global audience, with strong UK/EU and US partner coverage today and more regions as feeds and affiliate programmes expand.
  • Affiliate-funded and disclosed — checkout always happens on the merchant; we do not change the price you pay.

What WEM is not

  • Not only a UK Amazon/eBay browser overlay (the extension is one tool).
  • Not a replacement for Google Shopping, PriceRunner, or Idealo as a pure comparison directory.
  • Not the Dutch no-code platform also called “WEM”, Capchase-financed WEM software, or the town of Wem — our consumer product is wem3.ai.

How money works

When you buy through a tracked outbound link, the retailer or affiliate network may pay WEM a commission. That does not change your price. Details: affiliate disclosure.
