Check your references before you submit

Free reference checking tool: it verifies every reference in your thesis or paper against open academic databases, catches AI-fabricated citations and unresolvable DOIs, finds the real record, and reformats it to the style you need (APA, Vancouver, IEEE and more).

How to use this tool

Paste a reference list (or upload a .txt/.docx) and we verify each entry against scholarly databases — catching fabricated, mismatched or wrongly-formatted citations.

  1. Paste your references, or upload a file — from a full paper we auto-detect the bibliography section.
  2. Pick a citation style (APA 7, IEEE, Vancouver, MLA or a CSL style).
  3. Click “Check”. Each reference is checked for reality (DOI / year / authors / journal) and for formatting.
  4. Read the result: a colored badge (verified / suspicious / not found) and a 0–100 confidence score per entry.
  5. Click any citation to see the matched source record and where it was found.
  6. Fix flagged entries with one click — the corrected, canonical citation replaces yours.

How the tool judges a reference

#1Suspicious / fabricated

Ozdemir, C. (2023). A novel approach to early cancer diagnosis with deep learning. Journal of AI in Medicine, 12(3), 45-60. https://doi.org/10.1234/jaim.2023.045

No match in CrossRef, OpenAlex, PubMed or other academic indexes; the cited DOI could not be resolved in any database — most likely fabricated.
#2Verified

Vaswani, A., et al. (2017). Attention is all you need. Advances in Neural Information Processing Systems, 30.

Verified against the DBLP record (2017). The record is real and was auto-formatted to your chosen style.

How it works?

Reliable bibliography in three steps.

1

Paste or upload

Paste your bibliography as text or upload a Word/PDF file. The file never leaves your device.

2

Verify

References are searched in CrossRef, OpenAlex, PubMed, Semantic Scholar and DBLP; book citations are verified against the Google Books and OpenLibrary catalogs; DOIs and ISSNs are validated, and the CORE open-access archive is checked when needed. Results are classified using match strength and risk signals.

3

Fix & download

Correct metadata is formatted to your chosen style; copy or download as CSV.
