Why a citation checker matters (even if your BibTeX compiles)
A BibTeX file can compile perfectly while still being wrong. That’s why a citation checker is useful: it targets the metadata readers actually notice—title, author list, year, and venue—before mistakes turn into reviewer confusion.
If your references come from multiple sources (Zotero exports, publisher pages, old lab libraries), a citation checker catches drift early. A citation checker also helps teams keep citations consistent across multiple manuscripts.
