What it does

Written by AI from the README

Translates PDFs from within Zotero using PDF2zh or PDF2zh_next, keeping formulas and layout and producing bilingual or translated-only PDFs. Supports batch translation and several LLM services, and needs a companion translation server that runs on your computer.

Translating a whole paper usually means uploading it to a web tool and losing the layout. This runs the translation engine locally and attaches the result to the item, aimed mainly at Chinese-speaking researchers. Based on zotero-pdf2zh by guaguastandup.

Forks and copies

7 other plugins use the same ID as this one. Every Zotero plugin carries an ID, a name tag Zotero uses to tell plugins apart. These 8 plugins carry the same one, because people copied Zotero PDF2zh to make their own versions and kept its ID.Show what this means
  • You can only have one. Zotero sees them as the same plugin.
  • Installing another replaces it. If you install one of the others, it takes this one's place.
  • Check what you install. Several share this plugin's name, so make sure the file comes from the one you meant.

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. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
