The Google Keep note taking service that leaked out a few days ago has officially launched. There's a website and an Android app for now, and a post on the Google Drive blog it's intended for users to quickly jot down ideas. They're saved on Google Drive, and on Android 4.2.2 there's a lock screen widget available for even easier access. Check after the break for a trailer explaining the new service's features, or just hit the links below to try it out for yourself.Filed under: Software,
