Google Photos

Unlimited photo storage isn't new — plenty of other services offer it. Neither is automatic cloud backup. But like Gmail for your memories, Google Photos offers you both without sharing your secrets with the world. Using Google's scarily accurate machine learning, it automatically indexes your photos, picking out things like people, places, and things, making them completely searchable without needing to tag every damn shot. Add in support for 1080p movies, powerful integrated editing tools, and seamless sharing, and you've a strong incentive to sign up, especially considering it's free.
