Google is going to be bringing the Smart Compose feature it first introduced in Gmail to Google Docs. However, access to the function is currently limited to G Suite domain administrators that sign up for the beta. The feature is also limited to English right now. But as with other Google productivity-related features in the past, the plan could include a rollout to all users in the future.
Smart Compose uses machine learning to study your writing and suggest how to finish a sentence or correct a statement.
