Google is adding new logic to Chrome 150 that redirects some users to google.com/aimode when they try to access an internal AI-related Chrome experience called “cobr.”
The change was spotted by TechDows in a Chromium Gerrit commit, and it shows how Google is continuing to build AI Mode deeper into Chrome.
According to the Chromium change, Chrome will redirect “cobr” to google.com/aimode in three cases. First, when the user is not eligible. Second, when the user is not logged in. Third, when the user tries to access cobr from a non-Google search provider.
That last part is interesting because it suggests Google wants this experience tied closely to Google Search. In other words, if Chrome detects that the feature is being accessed outside the expected Google Search flow, it will send users directly to Google’s AI Mode page instead.
The change has already been merged into the Chromium M150 branch. The commit message is clear: “Add logic to redirect cobr to google.com/aimode.” The original change also lists multiple internal Google bugs, which suggests this was not a random experiment, but part of a larger cleanup or rollout plan around Chrome’s AI Mode integration.
The code touched several Chrome areas, including contextual tasks, WebView tests, omnibox tests, and UI-related tests. That does not necessarily mean users will immediately see a new button or interface, but it confirms Google is wiring this AI Mode flow into parts of Chrome where search, tasks, and browser UI can interact.
For now, there is no public explanation from Google on what “cobr” stands for. However, the redirect destination makes the intent obvious. If the user is not signed in, not eligible, or not using the expected Google Search path, Chrome will push them toward Google AI Mode instead.
This could become more visible once Chrome 150 gets closer to release.
