Memex is a browser extension that eliminates the time wasted on bookmarking, revisiting old web pages, or copying notes to scattered documents. Inspired by Vannevar Bush's vision of Memex, it offers full-text search, highlighting, annotation, tagging, list-making, and bookmarking capabilities. All personal data is stored locally, never leaving your computer, and can be backed up to the cloud. It also provides mobile app support and encrypted syncing, allowing for backups and restorations with multiple cloud service providers, as well as importing bookmarks and history from other services. Positioned as a productivity tool, Memex helps individuals, teams, and communities collect, annotate, and discuss the most valuable content and ideas found online.
