What it does

Written by AI from the README

Translates PDFs into side-by-side bilingual or translation-only PDFs, keeping layout, images and formulas. Uses a local engine with free Bing or Tencent translation, or your own DeepSeek or OpenAI-compatible API.

Reading English papers and lecture notes often loses the layout when translated. Windows and Apple Silicon Mac are verified, and text goes to the chosen translation service.

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews.
