Gemini Spark gains Chrome browsing to book flights and more

On August 3, 2026, Google's AI assistant Gemini Spark began browsing the web through the Chrome browser, leveraging users' saved passwords and logged-in accounts to research flights, start bookings, and schedule apartment viewings. The company presented only these two use cases.

The U.S. rollout started the same day, with additional regions to follow. It comes after Google extended Spark access to Google AI Pro subscribers in more than 160 countries.

Google detailed new safety measures against prompt injection, where hidden prompts on malicious websites or in user-generated content could trick the assistant into initiating financial transactions or stealing sensitive data. The company is investing in a layered defense that includes both deterministic and probabilistic methods, though it did not reveal specifics. Moreover, Spark never completes payments autonomously; it hands the final purchase step back to the user.

The assistant also integrates with Google's Workspace apps.
