Overview
- Google ended Project Mariner, a Chrome-based browsing agent, with its landing page noting the shutdown and a transfer of its technology to other Google products.
- Features from Mariner have been folded into Gemini Agent and AI Mode, which can take actions like archiving emails and helping book hotels inside Google’s services.
- The shift reflects growing favor for OpenClaw-style and coding agents that run through the command line, which lets models control apps and files more reliably than screen-reading bots.
- Browser agents struggled because they had to capture and interpret many screenshots of web pages, which drives up compute costs, slows responses, and often leads to inaccurate clicks.
- Rivals are steering in the same direction with efforts like Claude Code and Claude Cowork, OpenAI’s push to extend coding agents, Perplexity’s Personal Computer, and Meta’s reportedly developing “Hatch,” while security experts warn these deeper system hooks raise risks from prompt injection, malicious plugins, data leaks, and supply‑chain attacks.
