RefCheck.ai is a lightweight web tool for validating BibTeX references and spotting suspicious or inconsistent citations.
Users can upload a .bib file (or paste BibTeX content), watch a live verification pipeline in the browser, and receive a structured report that highlights mismatched fields (e.g., title/author/year) along with a suggested “best match” from trusted scholarly indexes.

RefCheck.ai treats each BibTeX entry as a claim and verifies it via a multi-source, evidence-driven matching pipeline:
-
Parse & normalize
BibTeX is parsed and normalized (basic LaTeX cleanup + canonicalized title/author/year) to reduce formatting noise. -
Multi-source retrieval
The system queries scholarly metadata providers (e.g., Semantic Scholar, Crossref, OpenAlex) to retrieve candidate works. -
Evidence-based matching
Candidates are scored primarily by title similarity, with additional signals from author and year (±1) consistency. The best-matching candidate becomes the reference “ground truth” suggestion. -
Three-level decision
verified: title + author + year (±1) all agree with the best matchuncertain: the work likely exists but has one or more mismatched fieldssuspicious: multiple strong inconsistencies or no plausible candidates despite reachable sources
RefCheck.ai supports bring-your-own Semantic Scholar API key:
- Without login or an API key, the tool runs in a degraded mode.
- After login, users can store exactly one API key in their profile (encrypted at rest) to enable full Semantic Scholar retrieval.
