SAN FRANCISCO — Google launched Gemini Spark, a 24/7 agentic AI assistant, in beta for subscribers of its AI Ultra plan in May 2026. The service, introduced at Google's annual developer conference, is designed to complete online tasks, summarize unread content such as emails, and organize personal workflows including expense tracking in Google Sheets.

Gemini Spark integrates with Gmail, Calendar, Docs, Sheets, and Slides, enabling users to assign “tasks”—a term Google uses instead of “prompts”—to automate actions across its productivity suite. The assistant operates via virtual machines in the cloud and can perform internet-based activities through a remote browser, though actions like sending emails or creating calendar events require user approval. Google CEO Sundar Pichai stated that Gemini Spark runs on virtual machines in the cloud and joked, "yes, you can close your laptop."

In testing, Gemini Spark scanned a user’s email and calendar to generate a daily recap with top to-do items and compiled weekend activity suggestions by analyzing Gmail newsletters and web content. For a birthday party, it extracted reservation details from an email—including the last four digits of a credit card used for a deposit—and produced a five-page plan with venue rules, dining options, and theme ideas based on the user’s Google Workspace history.

However, the assistant also exhibited limitations. When asked to include the user on a guest list for their own birthday party, it omitted them entirely. It suggested exclusively gay bars for after-party plans, citing past affiliations with groups like Stonewall Sports, and included age restrictions in an invitation deemed unnecessary for a 32-year-old’s gathering. In other tasks, it returned four newsletter summaries instead of five, provided a non-functional redirect link, and failed to complete a dinner reservation after triggering a phone verification code.

Gemini Spark also showed mixed results in commerce-related tasks. It recommended stacking Walgreens promo codes for extra savings, though one code was invalid despite meeting stated criteria. It compensated by highlighting alternative deals such as buy-one-get-one offers. When asked to create a packing list for a day trip, it generated accurate suggestions—including lawn chairs or blankets, water, sunscreen, sunglasses, a light layer for evening, a reusable shopping bag, and an umbrella—but could not import the list into Google Keep, offering instead to draft a Google Doc or email.
