Google shut down Project Mariner on May 4th, 2026, ending the experimental feature that was designed to perform tasks on behalf of users across the web. The Project Mariner landing page now displays a message reading: “Thank you for using Project Mariner. It was shut down on May 4th, 2026 and its technology voyaged to other Google products.”
Google first revealed Project Mariner in December 2024 and later updated it to handle up to 10 simultaneous tasks. Over the past year, the company integrated its capabilities into other AI tools, including Gemini Agent — which can archive emails or help book hotels — and AI Mode, Google’s AI-powered search feature.
The shutdown was first reported by Wired’s Maxwell Zeff.
Google has also previewed a Chrome feature called “auto-browse,” which can carry out multi-step tasks such as researching flight costs. Google has not confirmed whether auto-browse is powered by Project Mariner technology, though it addresses similar functionality to agentic web browsing tools offered by OpenAI, Perplexity, and OpenClaw.
The removal of Project Mariner as a standalone product may signal that Google is consolidating its agentic web capabilities into existing and upcoming products. Google’s annual I/O developer conference begins May 19th, 2026, where new AI features could be announced. Google did not immediately respond to a request for comment.
