Semantic Scholar is for search, but you can't just go there and look at everything that has been uploaded today as you do in arXiv, right? I know many people who check arXiv every day (myself included) but not Semantic Scholar, although I guess this might be highly field-specific.

What follows is totally offtopic, but to be honest I don't check Semantic Scholar much because I have a grudge with it. Profiles just don't work for authors with accented characters in the name (such as myself), papers get dispersed between multiple automatically-generated profiles. The staff is very helpful and will manually merge profiles for me when asked, but then I publish a new paper and wham, instead of incorporating it into the merged profile the system creates a new one. This has been going on for 6 years (if not more) and still unfixed.

For all the criticism that Google Scholar gets, I highly prefer it because it gets that right. It's extremely annoying when tools give you extra work for committing the sin of not having an Anglo-Saxon name (this is much more common than unaffected people would expect) and just don't seem to care to fix it.
