The update, presently rolling out for G Suite users on web, will use AI to point out errors in your email. If you’ve made a slight typo, Gmail will automatically correct the spelling for you.

I enjoy using some of Gmail’s nifty AI features, like Smart Reply and autocomplete; they’ve saved me a lot of time and helped me achieve Inbox Zero.
