At Google I/O 2018, the company demonstrated the Smart Compose feature that uses machine learning to autocomplete sentences. Smart Compose was launched as an exclusive feature for Gmail and only available via G Suite accounts and limited to Pixel 3 devices. In early 2019, Google expanded the feature to all Gmail users and later on in the year to Google Docs for G Suite accounts. Now, Smart Compose is rolling out on Gboard for messaging services, starting with Google Messages, Telegram, and WhatsApp.

Since at least 2017, Android app including Gmail and Messages (as well as the now-defunct Inbox and Allo) have had the Smart Reply feature that offers instant responses generated machine learning. The feature was also released for third-party messaging apps with the help of an API prior to the launch of Android 10. But, Smart Compose is a step ahead of Smart Reply as it suggests words that might follow as you're typing and these suggestions also change dynamically with each added word. Not just that, Smart Compose also allows you to tweak the message instead of sending it directly.

9to5Google notes Smart Compose is available with the latest beta of Google's keyboard app Gboard, presently v9.5.12.317844448 that was updated last week. Similar to Gmail and Google Docs, you can swipe right across the suggested sentence to autocomplete it.

The feature is also supported in popular third-party messengers like WhatsApp and Telegram other than Android Messages. But since it has been enabled by Gboard and not the apps themselves, we may see it on other messengers. Although I'm running the same version of Gbaord in India, the feature is not available for me, which means it might either be available only for an A/B test group or restricted geographically.
