Chrome OS Lock Screen Note Taking Coming Soon, First with Google Keep. I use Google Keep for note taking for many reasons. It is easy, free, and compatible with all my Google apps. I have an extension in Google Chrome that allows me to click and save any website, content, text, photo, or whatever. Soon, for those of you who use a stylus and Chrome OS, you will be able to make and save notes from the lock screen. Just click and draw or write on the screen and you can save your thoughts wherever, whenever. I prefer typing since my writing isn't the best. I do, however, enjoy taking notes on paper with my Echo Smart Pen. They are preserved in digital form by connecting to the Livescribe app on my computer. If you are comfortable writing with a stylus on a tablet or computer screen, however, watch out for the Google Keep integration.
