OpenAI Chrome extension lets ChatGPT read your tabs

KEY FACTS

OpenAI has updated its ChatGPT extension for Chrome so it can read the content of the tabs a user has open.
In Chat mode, ChatGPT can compare product details across tabs, such as size, price and return policy.
In Work mode, ChatGPT can send messages, fill out forms, organize tabs and manage calendars on the user's behalf.
The sidebar version of ChatGPT now taps the user's full browsing history, letting them issue tasks without switching pages.
The extension is available across all subscription tiers and is compatible with Chromium browsers including Edge, Brave and Opera.

PHYSIX OBSERVATION

The browser is shifting from an entry point into a context source for AI. After abandoning its own browser effort, OpenAI is using an extension to turn Chrome into its home turf. For users it is convenience; for Google it is traffic and data sovereignty being eroded further. Once AI can read tabs and history, the privacy boundary and platform countermeasures will be the next battleground.
