What it does

Written by AI from the README

Translates selected PDF text in Zotero using Codex models through your ChatGPT account. Translations appear in the selection popup and reading pane, can be saved as notes, and are cached locally.

Reading papers in another language means pasting passages into a translator. This translates in place and needs a ChatGPT plan, not an API key.

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.
