Interlinea is where the reading itself happens, not a tool you copy things into afterwards. Whole-document translation with formulas intact, AI answers that cite page numbers you can click, highlights that travel with a shared page, and clean exits to Markdown, BibTeX and Zotero. The reading is the record.

Interlinea turns every paper into a workspace: read, ask, annotate, revisit, and collaborate—all in one place.
