Check your references before you submit

Free reference check: every reference in your thesis or paper is verified against open academic databases; AI-fabricated citations and dead DOIs are caught, and the real record is reformatted to your style (APA, Vancouver, IEEE and more).

How to use this tool

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

  1. Paste your references, or upload a file — from a full paper we auto-detect the bibliography section. .bib/.ris imports are also supported.
  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), for formatting, and against the retraction database.
  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. Copy the “Repaired bibliography” (complete, in-order list — verified entries rewritten, the rest kept as-is and numbered for manual checking) or download it as Word.
  7. About to submit? Use the “Pre-submission check” card: enter the target journal and get a single Word report combining bibliography health, retractions and the journal's reliability.

Check your bibliography

Put each reference on its own line, or upload a PDF · Word · .odt · .rtf · text file — you can also drag and drop it onto the box below. Guest: 5 searches/day · Member: first day unlimited, then 20 references/day · Pro: unlimited.

Example scenarios — no bibliography at hand? Pick one; the tool fills the box with a sample reference and checks it right away.
File

The selected style determines the corrected bibliography below and the copied/downloaded output.

Your text is processed in your browser, is never stored and is never sent to Turnitin or any other plagiarism database.

Used from 110+ university and institution networks, by journal editors and researchers.

What do the colours mean?

Every reference is searched in the academic indexes and marked with one of three outcomes:

#1Verified

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

Green: a record was found and the title/authors/year match. The reference is real and was auto-formatted to your chosen style.
#2Unverified — please check

Devlin, J., et al. (2018). BERT: Pre-training of deep bidirectional transformers for language understanding. NAACL.

Yellow/orange: the source WAS searched but there is no certain match — here the title matches while the year differs (record says 2019). Not necessarily wrong; check by hand before submission.
#3Suspicious / 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

Red: no match in CrossRef, OpenAlex, PubMed or any other index; the DOI does not resolve in any database — most likely fabricated.
