Citeproof

Paste a draft or reference list and Citeproof looks up each citation in Crossref, DataCite, OpenAlex and doi.org. It shows the closest matching record, a confidence score and any problems it detects, such as a DOI that appears to point to a different paper, a year that differs, a work marked as retracted in OpenAlex, or a reference it could not find. For a claim and a paper, it quotes abstract sentences that may relate to the claim and notes numbers from the claim that do not appear in the abstract. Limitations: scholarly works only (not case law or web pages); evidence is based on abstracts, not full text; "not found" means the work isn't in these indexes, which is not proof it doesn't exist. Citeproof reports only what these sources return; it cannot prove that a source is correct or that it supports a claim.
