Summary
Google has pulled the plug on Project Mariner, an experimental feature designed to perform tasks for you across the web, as reported earlier by Wired ’s Maxwell Zeff. Google first revealed Project Mariner in December 2024 and later announced an update allowing it to perform up to 10 tasks at a time. Earlier this year, Google showed off a new AI-powered feature, called “auto-browse,” that can perform multi-step tasks in Chrome, like researching flight costs. With the removal of Project Mariner, Google may be making room for the other AI features that could make their debut during this year’s the reporter/O, which starts on May 19th.
