文献桥 · PaperBridge has Atlas grade B (use with care) because it contacts a server we couldn't identify: mupdf.com, and 2 more findings. It works with Zotero 7–10, 11 beta. Last checked 6 Nov 2026.
Downloads a .xpi file (28 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.
33
DownloadsAll-time downloads of its release files from GitHub, counting every update. Installs from elsewhere aren't counted.
35
ReleasesVersions published on GitHub. Everyone who has the plugin downloads each one again, which adds up in Downloads.

Lets Codex read your Zotero PDFs through a built-in local MCP bridge and create native highlights, comments and tags. It also imports annotations into Obsidian notes by collection. Windows, personal libraries only.
Moves from reading a paper with an AI to a structured note in Obsidian without copying by hand. Needs Codex and an Obsidian vault.
