Citation Checker

Use this when checking a bibliography for DOI/title mismatches and recorded retraction or correction notices in public Crossref metadata. Search returns at most 5 metadata candidates. Audit accepts at most 4 DOI/title pairs and makes at most 4 parallel unique DOI requests, each limited to 8 seconds and 1 MiB. No full text is fetched. Inputs are temporary; no customer-account access or stored progress. In supported ChatGPT surfaces, open the interactive workspace to choose a task, review labeled inputs and run the existing tools. Examples are public or synthetic, not saved customer records. The public website provides a labeled example, usage steps and prompts. The interface adds no account access or persistence.
