Could you build this?

Partial Translating text is trivial via LLMs, but preserving visual layout in complex multi-column academic PDFs requires precise layout segmentation and PDF document reconstruction.

What it would actually take: Building this requires a PDF layout analysis pipeline (e.g., using layout models like LayoutLM or PyMuPDF/pdfminer) to extract text bounding boxes, font attributes, math formulas, and vector elements. The translated text must then be refit into the identical coordinate space using dynamic font scaling, hyphenation, or typesetting engines without overflowing or destroying page structure.
