PDF ingest
Add a PDF and Minerva pulls its text in so you can read, search, and cite it alongside your notes. Most PDFs come in cleanly. Scanned documents — pages that are really just images of text — get one extra step.
Most PDFs
Whether you add a PDF from your computer or from a link, Minerva reads its text page by page and saves it as a source, along with any title, author, and date the PDF already carries. From there it behaves like any other source you've added: readable, searchable, and ready to cite.
Scanned PDFs
Some PDFs are scans, so their pages are pictures rather than text Minerva can read. When that happens, Minerva offers to recognize the text for you and asks before it starts. This runs entirely on your own machine.
A password-protected PDF can't be added until you remove its protection first. And if the same paper reaches you more than one way — say, a PDF now and a link later — see Citing & duplicates for how Minerva keeps them tidy.
