Gemini Spark: Google Expands AI Agent to AI Pro Users in US, Ultra Worldwide
Google has widened access to Gemini Spark, its “24/7” agentic AI assistant, rolling it out to Google AI Pro subscribers in the United States while simultaneously extending it to Google AI Ultra subscribers worldwide. According to Android Authority, the expansion began rolling out immediately, with Ultra subscribers also gaining local-language support for the tool. The move follows a limited early rollout of Spark earlier this year and marks the feature’s biggest availability jump since its debut.
What’s changing for Gemini Spark access
Starting today, Google AI Pro subscribers in the US will begin receiving Gemini Spark, while Google is also expanding access to AI Ultra subscribers worldwide, complete with local language support. That’s a meaningful shift from the tool’s original rollout, which was restricted to a small pool of testers on the pricier AI Ultra tier. 9to5Google, which covers Google’s ecosystem closely, reported separately that after launching in May with AI Ultra, Gemini Spark is now rolling out to Google AI Pro subscribers in the US, and it will “soon” be available to AI Pro members in other countries.
Not everyone is included yet. The rollout still excludes users in the EEA, UK, Switzerland, and Nigeria. Australia and New Zealand are not on that exclusion list, meaning AI Ultra subscribers in both countries should already be able to access Spark in their own language, while local AI Pro subscribers are set to get it once Google extends that tier beyond the US.
How Gemini Spark actually works
Google first unveiled Spark at its I/O developer conference in May 2026, describing it as a persistent, cloud-based agent rather than a conventional chatbot. In its own announcement post, Google said it was introducing Gemini Spark, a 24/7 personal AI agent that helps users navigate their digital life, representing a big shift for Gemini by transforming it from an assistant that can answer questions into an active partner that does real work on a user’s behalf and under their direction. The company added that Gemini Spark runs on Gemini 3.5 and uses the Antigravity harness, and is deeply integrated with Workspace tools such as Gmail, Docs and Slides.
Because Spark runs on Google’s own servers rather than a local device, it keeps working after a phone is locked or a laptop is shut. Google noted that because it is a cloud-based agent, Spark keeps working in the background even when a laptop is closed or a phone is locked, meaning it is ready to take complex tasks off a user’s plate. 9to5Google’s breakdown of the current build explains the mechanics behind that: Spark uses Connected Apps like Google Workspace and Search, Personal Intelligence, a remote web browser and computer with code execution, chats, Canvas, and location to accomplish workflows, introducing the concept of Skills as reusable instructions and Schedules as automated triggers, with a Task being the high-level goal a user wants accomplished. Users can have up to 15 tasks running at a given time, with Spark using the same compute-based usage limits as the rest of Gemini.
Workspace editing and a speed boost added mid-July
Ahead of this week’s wider release, Google had already been quietly stacking new capabilities onto Spark. Android Headlines reported that just two weeks after its last feature drop, Google began rolling out upgrades allowing Gemini Spark to interact directly with files inside Google Workspace, alongside a speed boost. Practically, that means the assistant can open, read, and edit Google Docs, with Google expanding that capability across other Workspace apps so Spark can modify private spreadsheets and presentations, read existing comments left on files, and make direct edits to shared team documents.
Performance also got an upgrade. Spark’s core engine is now over 50% faster, achieved through smarter sourcing that allows the AI to retrieve, process, and review multiple reference sources in parallel rather than scanning them one by one. Google also cleaned up how the assistant communicates when it needs input, with 9to5Google noting Spark will also stop sending mobile notifications for a task if a user is actively present in that task’s thread in the Gemini web app.
Privacy considerations as an agent gets closer to your inbox
Handing an AI agent direct access to email, calendars and shared documents inevitably raises privacy questions. CBS News, reporting around Spark’s original launch, noted that Google said Gemini Spark will need to obtain a user’s permission before executing “high-stakes actions like spending money or sending emails.” The outlet also quoted a Cornell researcher advising caution with any new agent: “The first time you onboard an assistant, you don’t know how good they are, so you try them out a little bit before you hand over your credit card,” he said.
Google’s own product page reinforces that connections are opt-in rather than automatic, noting that Spark can connect natively with apps like Gmail, Calendar, Drive, Docs, Sheets, Slides, YouTube, and Google Maps, though these connections are turned off by default and must be switched on in settings.
A desktop version and continued competition with rival agents
Spark’s next big step is arriving on desktop. Android Authority reported that Spark is expected to land on macOS in a much bigger way later this summer, working inside the Gemini desktop app so the AI agent can interact with local files and automate workflows directly across the desktop. That expansion sits inside a broader race among AI companies to build genuinely autonomous assistants, a race in which Google is positioning Spark against similar agentic products from rival labs.
For now, the immediate headline is simply availability: more people, across more of Google’s paid tiers, can try an assistant designed to work independently in the background rather than wait to be asked. With Australia and New Zealand absent from the current exclusion list, AI Ultra subscribers in the region are among those already able to put Spark to work, while local AI Pro users watch for the wider rollout Google has promised will follow the US.
