Google officially announced Keep yesterday through a blog post. Keep is Google’s note-taking app that was briefly revealed earlier this week. The Android app lets you store text, links, audio notes, images, and check lists and have it synchronized with Google Drive. You can make entries on the web or on the app. Google plans to roll out this ability directly on Drive as well. No official word yet on whether this will be available for iOS although just about all of Google’s mobile apps can be found on the App Store
Interestingly, Google had previously released a similar tool called Google Notebook for desktop browsers but it was shut down in July 2012.
