CiteTrue helps students, researchers, professors, reviewers, and librarians check whether citations are real and their metadata is accurate. Paste references, DOIs, or a bibliography to verify sources and flag mismatched details or potentially fabricated references, including those generated by AI. Use it to review a paper's bibliography, check AI-assisted research, or validate references before submission. CiteTrue also offers an MCP integration, CLI, Chrome extension, and Mac app for different workflows. Results provide evidence for review, not a final verdict; coverage can be limited for legal citations, non-English sources, books, and grey literature.
