The pitch sounds simple until you picture what changes: an AI assistant that keeps working after you stop talking to it.
Google is now rolling out Gemini Spark to Google AI Ultra subscribers in the US. days after the company announced the feature at Google I/O 2026. Instead of waiting for a prompt. Spark is designed to run 24/7 in the background. operating as an “AI agent” that can take care of tasks without constant user input.
Spark appears as a dedicated tab inside the Gemini web experience, sitting alongside the standard chat functionality. Google describes it as always-on—yet still under the user’s control. That “always-on” part is the heart of the feature. and it’s also why this rollout feels like more than another chatbot update. Spark is built to handle the kind of digital chores people normally juggle across multiple apps.
In practice, Spark leans hard into Google’s ecosystem. It can connect with Google Workspace apps including Gmail. Calendar. Drive. Docs. Sheets. and Slides to perform actions that typically require hopping between tabs and windows. Users can ask Spark to schedule meetings and manage invitations. search emails. summarize conversations. create documents. build spreadsheets. generate presentations. and organize files.
Google is also giving Spark access to connected services. Personal Intelligence features. the websites users are logged into. and remote browser tools that can interact with webpages on the user’s behalf. Sometimes that means Spark can browse. fill in information. and carry out actions without requiring the user to click through each step.
Behind the scenes, Google says Spark runs on cloud-based virtual machines using Gemini 3.5. The company’s point is clear: tasks can continue even if a user closes their laptop or locks their phone—background processing that turns the assistant from something you open into something that stays working.
Right now. Gemini Spark is only available to Google AI Ultra subscribers in the US. making it one of the most exclusive Gemini features Google has rolled out so far. But the direction is hard to miss. Spark isn’t positioned as a replacement for conversation. It’s positioned as the next step—AI that can take action while you’re away. and that could set the pace for where Gemini goes next if this rollout expands.

So it just… keeps running forever? Like background spying but called “help.”
If it can schedule meetings and summarize my emails then cool, but I’m still not trusting anything that can browse and fill stuff out. I’m gonna be checking every invite like a hawk.
Wait does this mean it’ll do my taxes too or am I mixing it up with that other AI agent thing? My cousin said something about it “taking over tabs” and honestly that sounds like it could mess up Gmail filters or whatever.
AI Ultra subscribers in the US only?? Figures Google’s gonna lock the useful stuff behind a subscription. Also “under user control” is doing a lot of work here, because once it has access to Drive and Docs it’s basically an intern that never clocks out.
