To use Smart Compose in Gmail, you first turn it on in Settings, then just start typing and accept the gray predictive suggestions with Tab (desktop) or a swipe/tap (mobile). It helps you write emails faster by completing common phrases and even full sentences based on your writing style.

What is Smart Compose?

  • Smart Compose is a predictive writing feature that suggests words or phrases as light gray text while you type in Gmail.
  • It uses machine learning and your past writing patterns to offer context-aware completions, especially for greetings, follow‑ups, and sign‑offs.

Turn on Smart Compose (Computer)

  • Open Gmail in a browser, click the gear icon, then “See all settings.”
  • In the General tab, scroll to “Smart Compose” or “Writing suggestions” and select “Writing suggestions on,” then scroll down and click Save Changes.

Turn on Smart Compose (Android & iOS)

  • Open the Gmail app, tap the menu (three lines), then go to Settings and choose your account.
  • Look for Smart Compose or predictive writing options and toggle them on; suggestions will now appear as gray text while you type.

How to actually use it while typing

  • Start composing an email or subject line; as you type, gray suggestions appear ahead of your cursor.
  • On desktop, press Tab to accept; on mobile, swipe right or tap the suggestion, or just keep typing to ignore it.

Tips, limits, and “latest news”

  • Smart Compose currently supports major languages like English, Spanish, French, Italian, and Portuguese, and is controlled at the Google Account level across devices.
  • Recent tutorials and videos in early 2026 focus on personalization options, which let Gmail tune suggestions more closely to your tone to keep emails smooth but still yours.
