Google Keep has been launched: it’s Google’s latest attempt to create a service for taking notes. Unlike Google Notebook, Keep is a Google Drive app (the Drive integration is not yet ready for public release), it doesn’t have a rich-text editor and it’s optimized for mobile.
There’s an Android app and a desktop site. Both use the sticky notes metaphor and you can choose the color for each note, add text, images, lists and voice recordings that are automatically converted to text in the mobile app. Both interfaces let you choose between the grid view and the list view.
