Google Docs' AI grammar suggestions are no longer limited to early adopters. The company is rolling out the machine learning tool for G Suite users, giving them an easier way to polish their reports. As Google outlined last year, this isn't a spelling checker with some grammar rules thrown in. The machine translation tech at the heart of the suggestions can detect nuances in grammar, whether it's a simple matter of word choice (like "their" versus "there") or the proper use of a subordinate clause.
