Artificial intelligence has moved beyond the phase of simple text-based chatbots to enter the era of autonomous and proactive systems, the so-called AI agents. At the center of this transformation we find Gemini Spark, a technology integrated into the Google landscape that redefines the concept of digital automation, and which was announced by Big G in the last few hours, in the annual Google I/O event. Based on the Gemini 3.5 Flash logical architecture and the Antigravity platform, this personal assistant operates in the background on virtual machines connected to Google Cloud, working independently even with devices turned off.
Unlike traditional chatbots – which require input for every single action – Spark applies the principle of personal intelligence: it coordinates complex, multi-phase workflows by natively connecting applications from the Workspace ecosystem, such as Gmail, Calendar and Sheets. The user always maintains oversight and decision-making control, as the system is designed to ask for permissions before performing crucial operations.
How Gemini Spark works and what it is used for
An AI agent doesn’t just answer a specific question: it is able to plan and execute a sequence of actions that point to an end goal. Spark realizes this ability through three functional pillars, namely activities, skills and planning, which work in synergy. Tasks connect the agent to Workspace applications; the skills define the operational rules and behaviors to be adopted for repetitive tasks, personalizing the experience without the need for new instructions; finally, schedules introduce triggers – conditional or temporal activators – which actually start the action at the exact moment it is needed.
Let’s move on to the utility of Spark. Every day a huge volume of information passes through our inboxes. Spark can act as a selective filter to optimize email management, without reading messages indiscriminately. Under our supervision, the agent isolates priority items, summarizes the week’s key themes from subscriptions, and drafts responses. If we need to update a working group on a project, for example, Spark can autonomously analyze relevant spreadsheets, documents and presentations to structure a coherent, ready-to-send text.
Sundar Pichai, CEO of Alphabet (the holding company that controls Google), when presenting Spark to the press, defined it in these terms:
It’s your personal AI agent that helps you navigate your digital life, acting on your behalf and at your direction. (…) It runs seamlessly on dedicated virtual machines on Google Cloud, (so) you don’t need to keep your laptop on to make sure it’s running.
The connection between Spark, the Google ecosystem, and third-party apps
An interesting advantage of Spark is its native connection with the Google ecosystem, which however is deactivated by default (so it is the user who has to activate it voluntarily and consciously). This eliminates the complex permissions setup with external software, typical of competing systems such as Anthropic’s Claude Cowork or OpenAI’s ChatGPT. It is possible to interact with the agent by writing to a dedicated Gmail address or monitor its progress from mobile via the Android Halo system, while the integration with protocols such as MCP will further expand its connections in the future also with third-party apps.
Google Spark availability
Currently rolling out to testers and 18+ subscribers to the Google AI Ultra plan in the US, access will quickly expand to a wider audience over the next few weeks.
