R Discovery

R Discovery is a research reading app from Cactus Communications, the team behind Paperpal, built around personalised recommendation rather than search: you set your research interests and it surfaces relevant new papers daily from a very large index. Its distinguishing features are practical rather than analytical, including audio playback so you can listen to papers while commuting, translation across many languages, reading lists and Zotero sync. Two things to weigh. The recommendation model suits staying current in a defined field and is less useful for exploring an unfamiliar area, where citation-mapping tools work better. And it is a discovery and reading app rather than a synthesis tool, so it complements rather than replaces something like Elicit or Scispace; the free tier covers reading with paid plans reported from a few dollars monthly adding advanced features.
