Google Keep is a chrome app that allows you to quickly capture things and recall them easily wherever you are. With this Google Chrome app you can save, access and organize information you want like you can create a text note, add photo or type up a quick list etc.
Everything you create with Keep syncs seamlessly between Android app (goo.gl/XTJqg) and on your Google Drive (drive.google.com/keep).
