Could you build this?
Partial A browser extension with selection Q&A, notes, and sync is easy to vibe-code, but faithful side-by-side PDF translation and formula copying require layout-aware PDF parsing and math recognition that are hard to get right.
What it would actually take: The UI and LLM calls can be built as a Chrome extension using pdf.js, a sync backend, and a translation API. The hard parts are preserving PDF layout during bilingual rendering and recovering LaTeX from formula glyphs, which need layout analysis, possibly tools like GROBID or MinerU, and iteration on edge cases.
