Google Pulls the Plug on Project Mariner, the AI Agent that Browsed the Web Like a Human
Google is folding Mariner’s web-browsing features into Gemini Agent and AI Mode after the experimental tool reached 10-task support for Google AI Ultra subscribers.
- On Monday, May 4, 2026, Google quietly shut down Project Mariner, its experimental Chrome-browsing AI agent designed to complete tasks on users' behalf across the web.
- Google debuted the tool in December 2024, showcasing it during the 2025 I/O conference as a way to automate web browsing by processing screenshots and recognizing page elements in real time.
- The screenshot-based approach demanded significant compute resources and was prone to errors, while industry momentum shifted toward faster, more reliable command-line agents that proved more efficient.
- Google folded the agent's capabilities into Gemini Agent and AI Mode, with core features absorbed into the Gemini API rather than being discontinued outright.
- Competitors like OpenAI, Meta, and Perplexity are developing similar agentic tools, signaling a broader industry pivot toward more efficient, non-visual architectures that prioritize speed and reliability.
