Google shuts Project Mariner after 17 months and moves its browser-agent technology into Chrome and Gemini Agent

Google DeepMind/Gemini in Chrome auto browse

Google closed Project Mariner, its experimental web agent that used vision to fill forms and book flights, and replaced its page with a farewell note. Its ideas and technology go into Gemini Agent and Chrome's auto browse rather than a separate product.

• Mariner ran for 17 months and could handle up to 10 tasks at once.
• It required the $249.99-a-month Google AI Ultra plan.
• Its staff moved to a new Google team building more capable agents.
