Evernote and Google Drive aren't exactly competing services, but they're similar. Both are places you go to vomit out notes and other documents worth remembering. Now the two are working together.
With this new integration, you can save files from Evernote into Google Drive. The inverse is also possible, in a way. You can drop Drive files inside of a note, and Evernote will create a more dynamic link. Changes you make in Drive will make their way over to Evernote.
Evernote says the functionality is in beta for Chrome and on Android. Support for other platforms is set to arrive soon, along with tighter forms of integration.
