Google Keep Chrome web app can be installed from Chrome Web Store as usual, after which you’ll find its icon among other Chrome apps. Clicking on it will open Keep in a separate window where you can manage all your notes.
What is great with this app is that, you can create or recall notes while do other things on your computer. Also, this app works offline too, so any notes you create are synced back to the web and your other devices when your connection returns.
