Corroba
Corroba is a web citation service for students, researchers, educators, and librarians.
What Corroba is
Corroba is a web citation service for students, researchers, educators, and librarians. It creates references from links, DOIs, ISBNs, PubMed IDs, or titles using bibliographic records. Supported styles include APA, MLA, Chicago, Harvard, IEEE, AMA, Nature, Vancouver, ASA, APSA, ACS, and Bluebook. Users can edit details, preview citations, build and restyle bibliographies, then copy or download them. Verify checks references from AI answers against databases and can flag hallucinated, mismatched, broken, or retracted citations. The converter rebuilds pasted citations through Crossref or DOI metadata, allowing up to 20 per free run. Integrity compares a draft with cited sources for up to 25 sources, but does not check uncited sources, the open web, or other students’ papers. Its PDF finder searches Unpaywall and OpenAlex for legal open-access copies. The Free plan is free, requires no account, and includes citation generation and export.
