The flow
From reading to citation, in four steps
Papyra unites what usually lives in separate apps: reader, citation manager and editor.
01
Read
Import your ePubs and read your way: paginated or scroll, typography, themes and focus mode.
02
Highlight
Mark passages in four colors, tag them by academic type and add notes or terms to your glossary.
03
Build
Gather clips from several books into a project and write it in the editor, with tables, images and formulas.
04
Cite
Each clip is inserted with its citation in your chosen format, and the bibliography builds itself on export.
