Main features

Scholar badges

Displays compact classification badges on Google Scholar search results when a reliable venue match is found.

Categories A, B, and C

Matches journal titles, ISSNs, and E-ISSNs against the bundled local DGRSDT/MESRS database.

Predatory records

Identifies records from the bundled predatory source data when the match is reliable.

Conservative by design

Separates conferences, books, theses, preprints, repositories, unclear venues, and unsupported results instead of forcing weak journal matches.

Books and theses

Distinguishes books, theses, monographs, and other non-journal items from journal publications.

Conference detection

Marks conference papers and proceedings separately unless exact journal evidence proves publication in a classified journal.

Manual popup search

Searches by journal title, ISSN, E-ISSN, or DOI from the extension popup.

DOI metadata

When necessary, DOI strings may be sent to Crossref to retrieve journal title and ISSN metadata.

Author statistics

Shows Category A and Category B publication counts on public Google Scholar author profiles.

Local database

Stores the bundled journal database locally in Chrome extension storage for fast lookups and MV3 service-worker restarts.

How it works

The extension reads visible publication metadata on Google Scholar pages in your browser.
It first detects likely publication type, such as journal article, conference, book, thesis, preprint, repository, report, or unknown.
It compares only trusted venue titles, ISSNs, E-ISSNs, and DOI journal metadata with the bundled local database.
When a DOI is visible and more metadata is needed, only the DOI string may be sent to Crossref.
A classification badge is added to the Scholar result or author profile.
Ambiguous or unsupported publications remain non-journal or Unclassified to reduce false positives.
