A recent leak suggests Google (GOOG) is working on a new note-taking application within its Drive cloud-storage suite. The service, known as Google Keep, allows users to create color-coded notes, add pictures and make checklists, according to Android Police. Google briefly activated the service over the weekend, however it has since been removed. Interestingly enough, a post from Google’s official Google+ page revealed the service in a screenshot last July. An image of a website thumbnail included the text “save to Google Keep,” suggesting the Evernote-like service has been in the works for quite some time. There has been no indication as to when Google will announce its new Keep service, which is also slated to be available as a standalone Android application.
