Due to my line of work, I find myself having to use both these services frequently, despite avoiding google as much as I can. I see a lot of alternatives out there for internet searching, but when it comes to specific fields, alternatives tend to be scarce.
PubMed instead of Google Scholar, would have to use specific search operatives to find what you need though. Also Elicit.org is a site that uses AI to find articles and break them down a little. I think with a free account you can get like x amount of searches, so may or may not be feasible for you. There’s also Scopus and Web of Science, but I have no experience using those.
I used to have access to scopus and web of science from my university, but I don’t have anymore, so I ended up using scholar, but looking for alternatives.
Elicit looks interesting, but I see that it requires a login, and has a bit weird privacy policy. I will check it in more detail, thanks.
