Zotero Language Categorizer has Atlas grade B (use with care) because a zotero:// link (a web page can open one) can make it install add-ons without asking you (from zotero-plugin-toolkit), and 1 more finding. It works with Zotero 8–10. Last checked 6 Nov 2026.
Downloads a .xpi file (0.3 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.
