Google has rolled out a new feature in Gmail that allows users to add events directly to Google Calendar using an 'Add to Calendar' button, which is powered by its AI, Gemini.

The Gemini sidebar button is conveniently located in the horizontal menu above the calendar, making it easy for users to access.

Currently, the Gemini sidebar is in testing and may be exclusive to Workspace customers upon its full release.

However, the initial test version does not include a direct button for voice interaction, which may limit accessibility for some users.

Many of Gemini's most useful features are locked behind a paywall, indicating a trend where advanced AI capabilities are not freely available.

As a Workspace Labs feature, Gemini's responses may not always be accurate, and users are encouraged to provide feedback to enhance its functionality.

A notable limitation is that users cannot add guests to events through this button, although future updates may address this issue.

While the introduction of Gemini in Calendar is viewed positively by some, others express skepticism about the increased AI presence in everyday tools.

This update is part of a broader series of enhancements powered by Gemini, which includes features for email summarization and improved search functionalities.

Currently, this feature is not available for the Gmail mobile app on Android and iOS, limiting its accessibility to desktop users.

Once users access the sidebar, they can see suggested prompts and have the option to enter their own queries regarding their schedule.

Users can input custom prompts, such as asking about upcoming meetings or adding recurring events like workouts, although conversation history resets upon closing the app.
