Amazon's Family Vault focuses on collecting and organizing images taken on multiple devices and accounts. While videos and other files can be stored too, storage is capped at 5GB across those five additional users. Once uploaded, the company says its new smart search capability can find matches based on "people, places or things." If those features sound familiar, Google's been doing the same with its AI-powered algorithms for quite a while.

It appears that Amazon has quietly been building other services around the expansion of Photos. Just last month, the retailer confirmed its intention to cash in on users storing their photos online with a new printing service. With Family Vault, Prime account holders can combine their images with those taken by others and order photo books, cards and other prints with free delivery.

Although the official launch is limited to US customers, it appears Prime subscribers outside North America can utilize the service via the web with their existing account. I was able to access Family Vault on Amazon.com using my Amazon UK account details, for instance.
