I hope sonething better comes along because google ruined their search engine a decade ago. stract.com is probabky the closest to what google used to be.

As for chatgpt, it is not an index. It cannot refer you back to infornation it was trained on because it doesn't build a massive indexed internet database.

It has some method of probable relations and conglomerarion of input. It is why it "hallucinates" information output, because it doesn't "know" what is wrong or right info, it just fetches data based on probabilities of connections.

It is good at suggesting new music or movies based on your list of media you like, but it is terrible with actual factual info
