Gmail expands Gemini thread summaries and Help me write

What the features do

AI Overview places a short summary at the top of a long email thread. Instead of scrolling through 20 replies, you can see at a glance whether a deadline moved or whether someone is waiting on you.

Help me write works from a simple instruction. Tell Gemini what you need and it drafts the email. It can also improve text you have already written, so it is useful for polishing as well as starting from scratch.

Availability and caveats

To use either feature, Gmail's smart features must be enabled in your account. Google says the rollout is already underway and can take up to 15 days to reach everyone, so the tools may not appear in your inbox immediately.

As with any AI-generated text, it is worth reading a draft before you press Send. A generated email is a starting point, and a personal touch still matters.

For workplace and school users, the expansion means less time spent catching up on busy threads and fewer blank compose windows. Whether the summaries prove reliable on messy, multi-topic conversations will be the real test once the features reach more inboxes.
