Citation checker

Academic Analyze and Write Check draft extract citations, apply APA/MLA format rules, and look sources up in CrossRef. CrossRef mainly covers journal articles with DOIs — books, older works, and non-journal sources are often absent. “Could not verify” means CrossRef had no matching record, not that there is a problem with the source.
