I was sceptical as well before trying it out, but it is unfortunately very practical to ask the AI sidebar about an information-dense website or even github codebase (just as dev examples).

There were of course many browser extensions that did this beforehand (and even better, by hyper-linking the exact text passage of answer segments), but the main differentiator is that most people don't use them/know about them, and this comes with a big tech nametag and it is free.

Could you please suggest some of those extensions? I've been looking for an agentic tool like that, but isolated as an extension.

Care to share some of those extensions? I feel like we're on the second/third wave of llm enhanced tools, and there's plenty of good stuff that got passed over from earlier waves of products/tool attempts.

Try search on a browser extension store for "AI Chat website" or similar. Also you can check out https://github.com/nanobrowser/nanobrowser.
