BibFetch

Fetch complete BibTeX with DOI from Crossref, Semantic Scholar & OpenAlex — directly from Google Scholar.

BibFetch fixes one of the most frustrating problems in academic workflows: Google Scholar's BibTeX export is broken. It omits DOIs, skips page numbers, and gets rate-limited when you need it most. BibFetch replaces Scholar's export entirely — no clicking "Cite", no 403 errors, no missing fields. HOW IT WORKS ━━━━━━━━━━━━ - A "📋 BibTeX" button is injected directly on every Google Scholar search result - Click it → complete BibTeX with DOI is copied to your clipboard instantly - Also works on Scholar citation detail pages - Open the popup on any Scholar page — the paper title is pre-filled automatically, just hit Fetch MULTI-SOURCE LOOKUP ━━━━━━━━━━━━━━━━━━ BibFetch queries three independent databases and merges the best data: ① Crossref — 200M+ papers, best for published journal articles ② OpenAlex — 400M+ papers, excellent for page numbers and open-access ③ Semantic Scholar — strong coverage of CS and biology Missing fields (pages, volume, issue) are automatically filled from fallback sources. ARXIV SUPPORT ━━━━━━━━━━━━ Preprints on arXiv are detected automatically. BibFetch assigns the correct DOI (10.48550/arXiv.XXXX.XXXXX) instantly — no API call needed. COMPARE PANEL ━━━━━━━━━━━━ Click the BibFetch toolbar icon to open the popup: - On a Scholar page, the paper title is pre-filled — just hit Fetch - Or paste any paper title to search from anywhere - See results from all 3 sources side by side with match confidence scores - Copy BibTeX from whichever source has the most complete data PRIVACY ━━━━━━ BibFetch does not collect, store, or transmit any personal data. All queries go directly to public academic APIs (Crossref, Semantic Scholar, OpenAlex). No tracking, no analytics.
