Google unveils Gemini 3, its most ambitious all-in-one digital assistant yet

Google has taken a significant step toward building a true all-in-one digital assistant with the launch of Gemini 3.

Announced alongside a sweeping update to its AI ecosystem, Gemini 3 introduces Gemini Agent, a tool designed to carry out multi-step tasks across Google services.

It manages users’ SMS messages, Gmail inboxes, and Google Calendar events through a single, autonomous agent system.

Since it is woven into Gmail, Calendar, and presumably Android messaging, it can operate in your actual digital life, not just in a separate chat window.

Gemini 3 also introduces Scheduled Actions, allowing users to create routines that run automatically, such as a daily digest of unread emails, a morning briefing on upcoming events, or a weekly report based on inbox activity. The feature supports up to 10 active tasks and notifies users when each one is executed.

While powerful, these automations are currently limited to paid AI Pro or AI Ultra plans and select Workspace tiers.

“Unlike earlier versions that primarily respond to text prompts, Gemini 3 is built to act. Users can ask it to reorganise emails, draft replies, coordinate meetings, extract dates from messages, or message contacts, all without manually switching between apps,” a Gemini spokesperson said during the launch.

“The model’s new reasoning capabilities allow it to parse context, interpret intent, and then carry out tasks independently once approved.”

The new level of access also introduces new privacy and security concerns, experts warn.

With Gemini able to read messages, emails, and scheduling data, researchers have highlighted potential vulnerabilities, including AI-triggered actions from malicious calendar invites or prompt-injection attempts.

However, Google says critical tasks such as sending emails or creating events will always require user confirmation.
