Google today announced it’s bringing a slew of updates to its Docs, Sheets, and Slides mobile apps — among which is Smart Compose. The apps will also get some minor updates including Dark Mode (yay).

Smart Compose is probably the most useful of the new additions. While the feature has been available in Gmail for years, and in the web version of Docs for a while as well, this will be the first time it’ll be available in the mobile apps. According to the preview images, the Smart Compose text will appear as gray words next to what you’re typing. You can fill in your sentences with the text by swiping it. Google boasts that this feature saves users 3 billion keystrokes a week, and based on my own use on web, I believe it.
