On 18 September 2026, Google opened AI Overviews in Gmail search to all paid users worldwide, as long as their Gmail is set to English. It is the latest step in a year where Gmail became a product built around AI. For professionals, especially outside the US, the question is practical: what can you actually expect from it today, and in which language?
What happened
In January 2026, Google announced that Gmail was entering the Gemini era. Thread summaries, the Help Me Write drafting aid and suggested replies became free. Asking your inbox questions in natural language and the advanced Proofread feature are reserved for Google AI Pro and Ultra subscribers. The rollout started in the US, in English. An AI Inbox, which gathers tasks and important contacts on a single page, opened to testers.
In May, at Google I/O, TechCrunch reported that AI Inbox was expanding to AI Pro and Plus subscribers, and that Google had announced Gmail Live, a conversational voice search initially limited to Ultra subscribers. Finally, the Google Workspace update of 18 September extended AI Overviews in Gmail search, previously US-only, to paid users worldwide whose Gmail language is English.
What it means for professionals
Gmail’s AI excels in two areas: understanding an inbox (summarizing a long thread, finding buried information) and helping you write a message when you ask. That is a real gain for anyone who spends time searching through email.
Three limits are still worth knowing. Language first: several features arrive in English before other languages, which matters for teams working in French, German or Spanish. Scope next: these tools only work in Gmail, while many businesses also run Outlook or other email services. And the way it works: Gmail’s AI responds when you call on it, one email at a time, rather than acting in the background. Following up on an unanswered email, forwarding a request to the right colleague or drafting a reply grounded in your own documents is still up to you. That is the ground Scribarius covers, working the same way in Gmail, Outlook and Zoho Mail.
What to do now
- Check your Gmail language and plan: some features depend on both.
- Try thread summaries on your longest conversations: it is the most immediately useful free feature.
- List what you still do by hand every day (follow-ups, sorting, forwarding) to see what built-in AI covers, and what it does not.
The next thing to watch is the arrival of these features in languages other than English, which Google has announced without a precise timeline. To organize your inbox now, read how to sort emails automatically in Gmail and Outlook.
