What Is Gemini Spark? Google's 24/7 AI Agent, Explained
Gemini Spark is Google’s 24/7 agentic assistant — an AI that keeps working on your stuff after you close the tab. Google introduced it at I/O on May 19, 2026 with Gmail integration as the headline feature, and on July 1 it landed on macOS in beta, folded into the Gemini desktop app. Unlike the Gemini chatbot, Spark isn’t a question-answer surface: you hand it ongoing jobs — watch this, organize that, keep this updated — and it runs them continuously.
Both of the original catches have since loosened, and one new one matters more than either. As of August 2026 Google’s help centre says Spark needs a Google AI Pro or Ultra subscription rather than Ultra alone, and runs wherever Gemini Apps are supported except the European Economic Area, Nigeria, Switzerland and the United Kingdom, on the web app, the mobile app and the Mac app rather than macOS only. What replaced them is an account-type wall: Spark requires a personal Google Account and is not available if you sign in with a work or school account. Here’s what it actually does today, and who it’s really for.
What Gemini Spark does today
The July 1 Mac release is where Spark stopped being an I/O demo and became a product you can run, and it now runs in the web and mobile apps too. Right now it can:
- Work with local files on your computer. Spark can read, sort, and organize files on your Mac, and turn them into Workspace docs — point it at a folder of receipts or meeting notes and it produces structured Google Docs and Sheets.
- Track topics in real time. Sports scores, stock moves, breaking news — Spark monitors what you tell it to and surfaces updates without being asked again.
- Run your Gmail. The original I/O pitch: Spark watches your inbox and handles the repetitive layer of email continuously, not one prompt at a time.
- Manage tasks and notes. The Mac release added connections to Google Tasks and Google Keep, so Spark can capture and organize alongside its other work.
Google also says cross-device assignments are coming — ask Spark something on your phone and have it work through the files on your Mac.
Integrations and MCP support
Spark’s launch integration list reaches outside Google’s walls: Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals, alongside Gmail, Tasks, and Keep. More importantly for anyone with a longer tool list, Spark supports the Model Context Protocol (MCP) — the open standard for wiring AI assistants to external tools — so it isn’t hard-limited to the apps Google has partnered with. (If MCP is new to you, here’s what MCP is in plain English.)
On the mail-client side, Spark vs Canary Mail compares the two most-cited options.
That said, the built-in list is short compared to what the category now offers, and everything non-Google beyond those named partners is a do-it-yourself MCP exercise.
The catch: a paid tier, and a personal account
The gate moved twice between July and August 2026, so it is worth stating what it is now rather than what it was at launch.
At I/O 2026 Google restructured its AI subscriptions: AI Ultra starts at $100/month (an entry Ultra tier that includes Gemini Spark, 5x Pro’s usage limits, and 20TB of storage), with the top Ultra tier at $200/month, cut from the previous $250. Spark launched exclusive to those tiers and US-only. Google then logged a rollout to Google AI Pro subscribers in the US on July 16, and widened availability on July 14 to all Gemini Apps languages, so the current help-centre requirement is a Pro or Ultra subscription and a location outside the European Economic Area, Nigeria, Switzerland and the United Kingdom. Pro sits at $19.99/month, which moves the entry price for Spark by a factor of five.
The wall that replaced geography is account type. Spark requires a personal Google Account and Google states plainly that the feature “isn’t available if you sign in with a work or school Google Account.” That is the constraint most likely to bite a business reader, because the identity that owns your company’s Workspace data is the exact identity Spark refuses. Google hedges it with “for now” in three separate places, so expect movement. The best Gemini Spark alternatives covers what to use if any of these still rule you out.
One more inconsistency to know about: Google’s own Spark overview page still describes the feature as available to “Google AI Ultra subscribers over 18 in select countries as well as select business users.” The help centre contradicts both halves of that. Where the two disagree, the help centre is the more specific and more recently corroborated source.
Gemini Spark vs ChatGPT Work
OpenAI launched ChatGPT Work on July 9 — one day after Spark’s Mac beta had settled in — and the two are the clearest head-to-head in AI yet, with different shapes:
- Spark is continuous; Work is per-task. Spark runs standing jobs (watch my inbox, track this stock) around the clock. ChatGPT Work takes a defined outcome, works on it for hours with its GPT-5.6 agent, and delivers finished spreadsheets, docs, and slides.
- Work has far more connectors. ChatGPT Work launched with 1,400+ connectable apps; Spark has a handful of partners plus MCP.
- Pricing structure differs. Spark is a fixed gate, now a Google AI Pro or Ultra subscription rather than Ultra alone; ChatGPT Work is usage-metered against your ChatGPT plan’s allowance, so heavy use burns your monthly budget.
- Spark owns the Mac’s local files; Work’s edge is breadth across SaaS tools.
The full comparison is in ChatGPT Work vs Gemini Spark.
What Spark is good at — and where it stops
Spark is genuinely strong at the Google-plus-Mac life: continuous Gmail handling, local file organization into Workspace docs, and ambient tracking. If your work lives in Google’s ecosystem and you already pay for AI Pro or Ultra, it’s the most “ambient” assistant Google has shipped.
Where it stops: it runs only on a personal Google Account, so the work identity that owns your company’s data is locked out, and four markets including the UK and the EEA are excluded. It doesn’t send email through Outlook, its non-Google integration list is thin without MCP tinkering, and the trigger vocabulary is Google-shaped, a clock, a Gmail filter or a news topic, rather than “when anything happens in any of my tools, act.” Nothing in it watches a file, not even in Google Drive.
A 24/7 agent on any account type: Carly
If what attracted you to Spark is the always-on part — an assistant that acts when things happen instead of when you prompt — you don’t need Google’s top tier to get it. Carly is a trigger-based AI executive assistant that runs 24/7 in the cloud: when an email lands, a meeting is booked, an invoice falls overdue, or a schedule hits, Carly acts — drafting and sending email on both Gmail and Outlook, updating your CRM, managing tasks and calendars.
Setup is a conversation, not a config screen: describe the system you want in plain English and Carly interviews you, then builds the workflow. It connects to 200+ tools natively — see integrations — and anything else via your own API key, pasted on carlyassistant.com/integrations. AI agents start at $35/month, and steps in a workflow that don’t use AI run free. It runs on a work account as readily as a personal one, which is the gate Spark has not opened yet.
Frequently Asked Questions
What is Gemini Spark?
Gemini Spark is Google’s 24/7 agentic assistant, introduced at I/O on May 19, 2026. Instead of answering one prompt at a time, it runs ongoing jobs — managing Gmail, organizing local files into Workspace docs, tracking topics in real time — and works continuously in the background. It runs in the Gemini web app, the mobile app and the Mac app.
How much does Gemini Spark cost?
Spark needs a Google AI Pro or Ultra subscription. Pro is $19.99/month; Ultra starts at $100/month after Google’s I/O 2026 pricing restructure, with a top tier at $200/month (down from $250). Google rolled Spark out to US Pro subscribers on July 16, 2026, so Ultra is no longer the only way in. There is still no way to buy Spark on its own.
Is Gemini Spark available outside the US or on Windows?
Partly, as of August 2026. Google now requires a Google AI Pro or Ultra subscription rather than Ultra alone, and Spark reaches everywhere Gemini Apps are supported except the European Economic Area, Nigeria, Switzerland and the United Kingdom. It runs in the web app, the mobile app and the Mac app, so it is no longer macOS-only, though there is still no dedicated Windows app. The remaining hard limit is account type: Spark is not available if you sign in with a work or school Google Account.
Does Gemini Spark work with non-Google apps?
Partly. It launched with Canva, Dropbox, Instacart, OpenTable, and Zillow Rentals integrations, and it supports MCP, so technically-inclined users can wire in other tools. The built-in list is much shorter than ChatGPT Work’s 1,400+ connectors or Carly’s 200+ native integrations.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
