Google shuts down Project Mariner

Google has shut down Project Mariner, an experimental AI feature that could automatically perform tasks for users across the web, as of May 4th, 2026. The company stated that the technology has been integrated into other Google AI products, particularly Gemini Agent (an AI that can perform multiple actions autonomously). Project Mariner was originally announced in December 2024 and could handle up to 10 tasks at once before being discontinued.
