Thank you for taking the time to try out the site!

arXiv has a keyword based search engine. It looks for words as is in the text. PaperMatch tries to find similar papers that are closer in meaning.

Here is an alternative approach: Take one paper that you like, copy the abstract from arXiv (or arXiv ID) and paste it in PaperMatch. This should help you find similar papers.

Very nice! Putting in an arXiv ID looks to produce many results that are much more relevant.

EDIT: You should provide this in an "information"/"about"/"how to use" dialogue or page to help people use the tool better.

Thank you!

I agree, since this site has the same interface, people expect it to work the same way. Which I was going for but didn't realise the cons of it. I will add an about section!
