Gemini Spark now works with Chrome, using signed-in accounts and saved credentials to automate web tasks with user permission. Sensitive actions require approval, and protections against prompt injection attacks reduce malicious manipulation risk. Web automation is rolling out in the US, while Spark expands to Google AI Pro users in 160+ additional countries. The integration allows Spark to handle repetitive tasks like contacting landlords, narrowing flight options, or preparing bookings before final confirmation. However, Chrome stores passwords, payment methods, browsing history, and logged-in accounts, raising privacy concerns. The article notes hesitation about trusting an assistant with personal account access, framing the trade-off as convenience versus privacy. Broader expansion is planned for the future.
