Inspired by the recent post, How can I be up-to-date on recent papers, practically?, I want to know what tools exist for finding recent papers (pre-print and published) on specific topics.
The recent post focused on how to stay up-to-date on a field, in general. Many of these answers provide helpful tools when trying to stay up-to-date on a broad field. (For example, benty-fields provides a nice daily arXiv display, but can only filter by broad, pre-defined terms). I am interested in a tool (like a website) that can organize papers published on topics that I can specify with a search term. I am not looking for email alerts.
The best thing I have found has been a Google Scholar search with custom keywords, filtered by most recent. If this is the best tool for my specific case, I can work with it. However, it would be ideal to not have to redo this search every day or deal with Google Scholar's slow indexing. Additionally, if the tool has more features, like saving to a "read later" list, that would also be great.
Does anyone have any tips?
