Google Keep is a service provided by Google which integrates note-taking and web surfing. Announced on March 20, 2013, Google Keep is available both on Google Play for the Android mobile operating system and on Google Drive as a web application
Web version
Instead of owning a subdomain under google.com as other major services of Google do, Google Keep appears like an attached part of Google Drive. Compared to other note-taking products, it has only some basic features: changing note color, inserting an image, and adding a new list. Users can also choose the List View or Grid View mode on its homepage.
Like Google Drive, there is no Save button for document editing in the web app of Google Keep; it saves everything automatically so long as users make a change to any document.
