Google introduced Project Mariner in December 2024 as an experimental Chrome feature designed to perform tasks in the browser on behalf of the user when instructed. Subsequent development expanded its capabilities so it could work on up to ten tasks simultaneously.
Some features tested as part of Project Mariner have been folded into other Google offerings. For example, Gemini’s agent mode now includes capabilities that can handle tasks such as booking a hotel or archiving a user’s emails.
A Wired reporter noticed that Google has shut down the Mariner project: a notice on the experiment’s website states the effort ended on May 4. Google says the end applies to the Mariner name, while the underlying capabilities have been migrated into other Google products.
As The Verge highlights, this year Google has been unveiling several AI features related to automated browsing. One example is asking the browser-integrated AI to find the most budget-friendly flight to Stockholm.
In short, Project Mariner as a named experiment is finished, but its automated browsing technologies continue to live on within other Google products.
