Alexandria

Alexandria is a application for managing a local store of scientific papers.

Typically starting with a directory of PDFs, it extracts metadata (title,

authors, year, DOI, journal) from the text of the PDF, consults CrossRef and

OpenAlex, then presents a searchable, filterable card browser.

Alexandria tries to make it easy to find and add related papers.
