Search engine is one of my main uses. Traditional search engines are worse than they used to be at a basic text search, and ChatGPT has the added bonus of being able to parse complex text and “figure out” what you mean when describing something that you don’t have a name for. You have to ask it for sources rather than just reading whatever it generates, and/or do traditional searches on the keywords it provides.
I don’t really understand why everyone’s telling you about torrents when you don’t need them to watch movies. Like, it’s nice if you want Blu Ray quality or have bad internet or something, but you don’t need to download stuff unless you really want to. I just use uBlock Origin with Firefox and one of a few streaming sites. You can find a list here: https://wiki.dbzer0.com/piracy/megathread/movies-and-tv/ (Scroll down to streaming and try one out.) It works on mobile, too.
Sometimes you’ll have to check multiple sites to find older, more obscure things, but for the most part they only really differ in their UI. Some anime sites even have options to skip the intro/outro and autoplay the next episode.
