Google has shut down Project Mariner, the AI browser experiment it introduced in 2024 that could book hotels or clean up your inbox, as Gemini Agent and other agentic tools take over.

Google has pulled the plug on Project Mariner, an experimental feature designed to perform tasks for you across the web, as reported earlier by Wired’s Maxwell Zeff. The Project Mariner landing page now contains a message that says: “Thank you for using Project Mariner. It was shut down on May 4th, 2026 and its technology voyaged to other Google products.”
