What Gemini Spark actually is

Gemini Spark is Google’s 24/7 personal AI agent inside the Gemini app. Sundar Pichai introduced it at I/O on May 19, 2026. The marketing line is: give it a task, it keeps working in the background, even if the phone and laptop are off.

It is not a new chatbot that replaces Gemini. It is an agent workspace next to chat. You turn it on. Connections are off until you enable them. It is designed to ask before big moves.

Pichai said Spark runs on dedicated virtual machines on Google Cloud, on Gemini 3.5 and the Antigravity harness. On August 19, 2026, Google posted that Gemini 3.7 Flash is in Gemini chat and Spark for AI Pro and Ultra.

What you need

The current help article is stricter than the launch blog:

• 18 or over
• A personal Google Account. Work and school accounts are out
• Google AI Pro or Ultra
• Keep Activity on
• Gemini on web, mobile, or the Mac app

It is not available in the European Economic Area, Nigeria, Switzerland, or the United Kingdom, even where Gemini Apps otherwise work.

At I/O, Spark started with trusted testers, then a US Ultra beta. The July 30, 2026 post expanded Pro access in over 160 additional countries. The Spark overview page still talks about Ultra in select countries and some business users. Use the help article for the gate, not the marketing FAQ.

The launch week is not the same as “it works on this login today.”

Tasks, skills, and schedules

Help splits the product into three pieces:

• A task is the goal. “Plan and manage my business trip to London.”
• A schedule is when. Time of day, or an event such as a delayed flight. These are not the scheduled actions in ordinary Gemini chat.
• A skill is reusable how. Tone for mail, a travel-booking recipe, extra context you would otherwise retype.

The official Spark page uses the same split. Example: every Monday at 9 a.m., scan last week’s mail, recap what matters, suggest a to-do list, block deep work on the calendar. Another: read the last 50 emails you wrote, turn that into a “ghostwriter” skill, call it on every draft.

To start a task: gemini.google.com, sidebar Switch to Spark, describe the work. On Mac: Gemini app → Spark → Tasks. First-run setup can be conversational: type set up, get started, or interview me.

What it can touch

With Connected Apps on, Spark can use Google Workspace: Gmail, Calendar, Drive, Docs, Sheets, Slides, Keep, Tasks. Search services (Search, Finance, Flights, Hotels, Maps), YouTube, Contacts. June 30 added Canva, Dropbox, Instacart, OpenTable, Zillow Rentals, plus custom MCP.

The help page lists Workspace actions in more detail than the brochure. Gmail: search, summarize, draft, reply, forward, labels. Calendar: check, RSVP, schedule, move, cancel. Docs/Sheets/Slides/Drive: search, create, edit; shared-file edits need confirmation. Keep: find and create notes. Tasks: Spark can bulk-add, update, and delete private tasks without confirmation. Read that request before you send it.

It does not roam the inbox for fun. Google’s own FAQ: Spark does not read email indiscriminately. It works under the tasks you set.

Chrome auto browse

July 30, 2026: Spark can, with permission, use logged-in Chrome sessions and saved passwords for web errands: apartment viewings, flight research, starting a booking. Payments stay in your hands. Google cites prompt-injection defenses and a handoff for sensitive steps. US first, more regions later.

Help is more mechanical. Auto browse on your Chrome is desktop Chrome only. The machine has to stay awake. If you close the lid, Spark may continue in a remote browser, then stop at sign-in until you take over. First connection asks Chrome. Every browsing task asks again. You can shut it off under Settings → AI Innovations → Gemini in Chrome.

Local Chrome sees the same signed-in sites you do. Help says Spark can share name, contact info, files, and other details with third-party sites while it works. That is the cost of “use my logged-in session.”

Mac files

June 30, 2026: Spark in the Gemini macOS app can sort PDFs in Downloads, build a Sheets budget from invoices on disk, and schedule updates. Access is only the files you grant. At that post it was a US Ultra beta, 18+, from gemini.google/mac. Help now treats the Mac app as a Spark surface and notes you can drive a set-up Mac from another device.

Do not assume every Pro user in every country has local-disk Spark.

Limits and how to stop it

Spark shares Gemini’s compute-based usage limits. Complexity and request count both count. You can have up to 15 tasks running. A sixteenth waits. A schedule will not fire if 15 are already going.

To watch work: open the task thread and the work panel. Progress, files read or written, schedules, skills and apps. Pause a schedule. Stop in the Spark box cancels the task. Take over grabs the remote or local browser.

Turn Spark off in Gemini Spark Settings. That deletes remote browser data and remote code-execution data. It does not wipe Chrome’s local history, and it does not delete your tasks, threads, schedules, or files Spark already wrote. Schedules stay paused until you turn Spark back on.

Cancel or drop below Pro/Ultra and you lose Spark. In-progress tasks finish. Schedules pause. Skills turn off. The data is kept.

Prompt injection

Help calls Spark experimental. Gemini can make mistakes. If a schedule runs while you are offline, you may not stop an unintended action in time.

Prompt injection is in the same article: a page, email, document, or .md file can hide instructions the agent will follow. Google’s examples include posting private mail to a public site, forwarding Gmail to an outside service, or running hostile code. Confirmation prompts, take-control mode, and site limits are mitigations. They are not a guarantee.

Spark is the consumer face of Google’s agent bet: a cloud VM, Workspace connectors, optional Chrome, optional Mac files. It is also a long-running process with your mail, calendar, and (if you allow it) logged-in web. Start with read-and-summarize. Keep the 15-task cap and the confirmation prompts in view. Recheck the help article when a feature is US-only this week and global next month.
