Description
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.

Could you build this?
No Translating whole technical papers while preserving complex mathematical formulas, layout geometry, and typesetting is an extremely difficult document-engineering and computer-vision problem.
What it would actually take: A production version requires a sophisticated layout-analysis engine (like Nougat or custom YOLO/LayoutLM models) capable of segmenting text blocks from LaTeX equations, tables, and vector graphics. The extracted text runs must be translated contextually without mutating math tokens, followed by a headless typesetting engine (like Typst or TeX) to reconstruct the PDF layout cleanly. This requires deep systems and document-parsing expertise in PDF DOM structures, bounding-box coordinate tracking, and font rendering.
