Project Mariner

Google Project Mariner is an experimental AI agent developed by Google DeepMind that autonomously browses and interacts with websites using the Gemini 2.0 foundation model. Designed as a research prototype exploring the future of human-agent interaction, Project Mariner can take control of Chrome browsers, navigate websites, and complete complex multi-step tasks by understanding and reasoning across web elements including text, code, images, and forms.

Key Features:

• Autonomous Web Navigation - Takes control of Chrome browser, moves cursor, clicks buttons, fills out forms, and navigates websites like a human user through an experimental Chrome extension
• Gemini 2.0 Powered Intelligence - Built on Google's advanced multimodal AI model capable of understanding and reasoning across diverse data types including text, images, and code
• Observe-Plan-Act Loop - Captures browser state, analyzes data to formulate action sequences, and executes planned interactions while keeping users informed of decision-making process
• Multi-Task Processing - Enhanced cloud-based virtual machine operation allowing up to 10 simultaneous tasks while users work on other projects in the background
• Teach & Repeat Functionality - Learns demonstrated workflows and replicates similar tasks in the future with minimal input, enhancing efficiency and user convenience
• WebVoyager Benchmark Performance - Achieved state-of-the-art result of 83.5% on real-world web task evaluations when working as a single agent setup
• Safety and Security Controls - Operates only in active browser tab, requires user confirmation for sensitive actions like purchases, won't accept cookies or sign terms of service
• Developer API Integration - Capabilities being integrated into Gemini API and Vertex AI for developers to build applications powered by the agent

Use Cases:

• Online shopping and price comparison across multiple websites
• Flight and hotel booking with automated form filling
• Recipe research with automated grocery list creation and shopping
• Job hunting with personalized listing searches based on resume data
• Furniture assembly task coordination through service platforms
• Ticket purchasing for events and entertainment
• Research tasks requiring multi-step web navigation
• Restaurant reservations and appointment scheduling
