What it does

Written by AI from the README

An AI chat sidebar in the PDF reader: summarise, explain selections, translate and ask questions, adding page text, notes or images as context. Uses an OpenAI-compatible API or local Codex, OpenCode or DeepSeek Harness, and saves answers as child notes. Windows and Zotero 10.

Keeps one conversation per paper inside Zotero instead of a separate chat app. Selected text goes to your chosen provider. Documented in Chinese.

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.
