What it does

Written by AI from the README

Translates a whole English paper into Chinese beside the original in the PDF reader. Exports a Chinese-only PDF and a bilingual PDF, using four free engines (Tencent, Youdao, MyMemory, Google) with no API key.

Reading English papers in Chinese usually means pasting passages into a translator one at a time. Its developer says it needs Zotero 9 on Windows and has been tested only there.
