Product summary

Review the store description, core capabilities, and common use cases.

Zotero Library Checker is a Chrome extension that automatically checks whether the academic paper you are currently viewing is already saved in your Zotero library.

Simply open a paper page, and the extension will compare it with your local Zotero library. If the paper has already been saved, a direct link to the matching Zotero item is displayed. There is no need to manually open Zotero and search for it.

By checking before saving, you can prevent duplicate entries in your library. When a match is found, you can quickly open the saved item to review your notes, confirm details, or continue citation work without interruption.

Key Features

* Read-only design (does not add, edit, or delete items in Zotero)

* Works entirely in your local environment (no external server communication)
