What it does

Written by AI from the README

A side-by-side English and Chinese reading view for papers, with each English paragraph followed by its translation. Uses structured full text from PMC or publishers where available, falling back to PDF parsing. Also supports figure and table caption translation, multicolour highlights and notes. Needs Windows, a DeepSeek API key, and a bundled local service installed with it.

Reading medical and scientific papers in English is slow for Chinese-language readers. This puts the translation next to the original text. Aimed at Chinese-language research.
