Took me a while to realise I can just type search queries into ChatGPT. e.g. simply "london bridge history" or whatever into the chat and not only get a complete answer, but I can ask it follow-up questions. And it's also personalised for the kinds of responses I want, thanks to the custom instructions setting.
ChatGPT is my primary search engine now. (I just wish it would accept a URL query parameter so it could be launched straight from the browser address bar.)
