Problem

Users worry that AI chat tools silently collect browsing activity for ad tracking, persisting conversation context which skews sensitive research and clashes with privacy expectations.

I know people use chat bots differently and I get that companies see value in personalization, but to me it is extremely valuable that I can start a chat without context.When researching a topic a chatbot can be quite sensitive to certain wording and those can end up steering definitions. Two context free chats on the same topic can go in very different ways depending on how you word things, but when using the notebook feature in Gemini, where every chat becomes part of the context you completely lose the ability to discover if a topic is vaguely defined or have many definitions.

The technology isn't anything new but, it's the context that makes it so uncomfortable.People have very different "expectations" of privacy when they're having a conversation with an AI VS when they're browsing something like FacebookNot to mention Facebook is free whereas you pay for a GPT subscription

To me, this quote just about sums it up:> The mechanism is standard adtech. What has no precedent is running it on an AI chat product.As someone who has been well aware of this mechanism for quite some time, I still feel icky anytime I re-read the details of it.What a time to be alive.

MDN lists how different browsers prevent this: https://developer.mozilla.org/en-US/docs/Web/Privacy/Guides/...Firefox, Brave and Safari do. Chrome and Edge do not.
