Downloads a .xpi file (3.2 MB). In Zotero, open Tools → Plugins and install it from the file.
In useAn estimate of how many copies of Zotero have it: Zotero downloads each new version once for every copy that has the plugin, so we count the downloads of its most-downloaded recent release. Rounded. Plugins that update from outside GitHub count low.

What it does

Written by AI from the README

Adds an AI chat sidebar that uses the open paper's title, authors, abstract and full text as context. Selected text gets quick actions such as explain, critique, summarise and translate, replies can be saved as PDF annotations, and PDFs can be parsed to Markdown with MinerU. Needs an API key for your chosen model provider.

Discussing a paper with an AI normally means copying text into a separate chat. This keeps the conversation beside the PDF and saves useful answers back.

Your rating of MarginMind v1.3.3

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.
