Journal Check — always-fresh journal rankings

Journal Check adds journal ranking badges directly to Google Scholar, PubMed, arXiv, and Semantic Scholar — so you can assess a paper's venue quality without switching tabs.

── WHAT IT SHOWS ──

Next to each search result, Journal Check displays one or more ranking badges drawn from the world's most-used academic quality lists:

• SJR (SCImago Journal Rankings) — quartiles Q1–Q4 for 30,000+ journals
• ABDC — Australian Business Deans Council list (A*/A/B/C)
• ABS AJG — Academic Journal Guide by the Chartered ABS (4*/4/3/2/1)
• FT50 — Financial Times list of top 50 business journals
• CORE — Computer Science conference & journal ranking (A*/A/B/C)
• CCF — China Computer Federation venue list (A/B/C)
• h-index — journal h-index sourced from OpenAlex
• Citation impact — cites-per-work quartile computed from OpenAlex data

You choose which signals matter to you. The strongest enabled signal drives the badge color.

── WHERE IT WORKS ──

• Google Scholar (scholar.google.com)
• PubMed (pubmed.ncbi.nlm.nih.gov)
• arXiv (arxiv.org)
• Semantic Scholar (semanticscholar.org)

── ALWAYS FRESH ──

Rankings are refreshed every month from primary sources. You never look at stale snapshots that were locked in years ago.

── PRIVACY FIRST ──

Journal Check never reads the content of papers you view. It only requests the journal name or ISSN from each search result to look up rankings. No personal data is collected.
