We've already seen Gemini appear in search results, text messages, and more. In Google's latest update to Workspace, Gemini will be able to add calendar appointments from Gmail with a single click. Well, assuming Gemini gets it right the first time, which is far from certain.The new calendar button will appear at the top of emails, right next to the summarize button that arrived last year. The calendar option will show up in Gmail threads with actionable meeting chit-chat, allowing you to mash that button to create an appointment in one step. The Gemini sidebar will open to confirm the appointment was made, which is a good opportunity to double-check the robot. There will be a handy edit button in the Gemini window in the event it makes a mistake. However, the robot can't invite people to these events yet.The effect of using the button is the same as opening the Gemini panel and asking it to create an appointment. The new functionality is simply detecting events and offering the button as a shortcut of sorts. You should not expect to see this button appear on messages that already have calendar integration, like dining reservations and flights. Those already pop up in Google Calendar without AI. The new button opens Gemini in Gmail and requests a calendar appointment, which can save you some keystrokes.

This can make scheduling appointments particularly vexing. In our experience, Gemini often gets confused with dates, particularly if your email thread includes people discussing multiple possible meeting times. And making a calendar appointment incorrectly can have real-world consequencesyou don't want to be the person who missed an event because you trusted AI.Google says this feature will begin rolling out today, but it could take upward of two weeks to reach all users. It's also limited to English and the Gmail web interface at this time. You won't see it at all if you're using a Google account without premium AI access. Like many of Google's Gemini integrations, this one is only available to those paying for AI tools (whether they wanted to or not). However, even the cheapest AI-enabled plans, like Business Starter, are eligible. Individual users with Google One AI Premium will also get the new calendar button.Ryan WhitwamSenior Technology ReporterRyan WhitwamSenior Technology Reporter Ryan Whitwam is a senior technology reporter at Ars Technica, covering the ways Google, AI, and mobile technology continue to change the world.
