Citation & References

Wraps ALLCAPS tokens in braces so BibTeX preserves capitalisation.

Strips non-required fields from .bib entries for clean submissions.

Sorts grouped in-text citations numerically, e.g. [3,1,2] → [1,2,3].

Converts RIS export format into clean, well-formed BibTeX.

Toggles suppress-author mode for citation formats that separate author from year.

Fetches and verifies metadata for a DOI via the CrossRef public API.

Scans a document for orphaned citation markers with no matching reference.

Anonymises self-citations for double-blind submission.

Normalizes inconsistent author name formats to BibTeX, APA, or Vancouver style.

Expands abbreviated journal names to full titles or compresses them using NLM abbreviations.

Fixes hyphen vs en-dash in page ranges, collapses duplicate pages, and flags reversed ranges.

Identifies the citation style of each reference in a list and reports the dominant style.

Finds orphaned in-text citation markers and either resolves them to matching references or removes them cleanly.

Converts all references in a list to a single chosen citation style — APA, Vancouver, MLA, Chicago, or IEEE.

Converts verified DOI metadata from CrossRef into a formatted citation in APA, BibTeX, Vancouver, or Chicago style.

Convert any ISBN-10 or ISBN-13 to a complete BibTeX @book entry using Open Library metadata — paste an ISBN, copy ready-to-use BibTeX.

Paste a DOI or a list of DOIs to instantly check whether any have been retracted or have expressions of concern, using the CrossRef API.

Upload or paste a .bib file to detect duplicate references — matches by DOI, title similarity, or both — and shows exactly which entries conflict.

Enter an arXiv or bioRxiv DOI/ID to find whether a peer-reviewed published version exists — looks up CrossRef for the canonical DOI.

Paste BibTeX entries to check that every required field is present for each entry type (@article, @book, @inproceedings, etc.) — flags missing and unknown fields.

AI reviews your reference list and flags incomplete or low-quality citations — missing volume, issue, page numbers, DOIs, or publisher info — with a completeness score.

AI rewrites your reference list to match a target citation style (APA, Vancouver, Harvard, Chicago, Nature) — paste references, choose style, get formatted output.
