SKU: project-mariner
Project Mariner is an AI agent prototype from Google DeepMind, designed to autonomously execute tasks within the Chrome browser. By controlling web navigation, Mariner can perform actions such as online shopping and information retrieval, aiming to enhance user productivity by automating routine web-based tasks. Currently in early testing phases, Mariner represents a significant step in integrating AI agents into daily digital interactions, operating under user supervision to ensure accuracy and relevance.

Project Mariner demonstrates high-level autonomy in web navigation and task execution (83.5% WebVoyager benchmark success rate), using Gemini 2.0's multimodal reasoning to automate complex workflows like form-filling and data collection. However, its autonomy is constrained by design limitations: inability to complete purchases (requiring final user confirmation), operation limited to active Chrome tabs (no background processing), mandatory user observation during actions (5-second delays between steps), and built-in restrictions against accepting cookies/terms. While it autonomously handles task decomposition and cross-website navigation, critical decisions remain user-dependent.
