AI CITATION VERIFICATION

Verify AI-Generated Citations

ChatGPT, Claude, Gemini, Perplexity, and other AI tools frequently generate citations that look real but may be fabricated. Verify AI output before relying on it.

No client facts needed. Do not paste confidential information. CiteClear works with citations only.

CiteClear provides citation triage, not legal advice. Always manually verify before relying on any authority.

Why AI-Generated Citations Need Verification

Large language models generate text that appears authoritative and well-researched, complete with citations that look properly formatted. However, these citations often contain errors:

~15-25%
AI citations contain errors
~5-10%
Are complete fabrications
<60%
Can be verified without errors

These error rates vary by task complexity, model, and prompt engineering, but the pattern is consistent: AI citations cannot be trusted without verification.

What CiteClear Checks For

Format Validation

Checks if citations follow proper structure for their type (case, statute, DOI, URL, etc.)

AI Hallucination Patterns

Detects common patterns in fake AI citations: impossible numbers, fake circuits, future dates

Malformed Citations

Flags citations that are incomplete, improperly structured, or missing required elements

DOI/URL Validation

Verifies DOI and URL formats are structurally valid and properly formed

Deduplication

Identifies and removes duplicate citations from your input automatically

Search Links

Provides direct links to Google Scholar, official databases, and verification sources

Deterministic First, AI-Assisted Second

CiteClear focuses on provable issues: format problems, impossible values, malformed identifiers. It doesn't make interpretive judgments about whether a source exists — that's what the search links are for.

Frequently Asked Questions

Which AI models can CiteClear verify?

CiteClear can verify citations from any AI model including ChatGPT (3.5, 4, 4o), Claude (3, 3.5, Instant), Gemini (1.5, Flash), Perplexity, Microsoft Copilot, and any other text-generating AI. The verification works on the citations themselves, not the specific AI that generated them.

What types of citations can be verified?

CiteClear verifies legal citations (cases, statutes, regulations), academic citations (articles, books, papers), web sources (URLs), DOIs, and other reference identifiers. It detects malformed citations, suspicious patterns, and provides search links for manual verification.

Does CiteClear work with different citation styles?

Yes. CiteClear recognizes Bluebook (legal), APA, MLA, Chicago, IEEE, Harvard, and other common citation styles. It analyzes the structure and format of citations regardless of the specific style used by the AI.

How does CiteClear detect AI hallucinations?

CiteClear uses pattern matching to detect common AI hallucination indicators: impossible reporter numbers (999 F.4th), non-existent courts (13th Circuit), future dates, generic party names, malformed identifiers, and other structural red flags that suggest the citation was fabricated.

Can CiteClear verify foreign citations?

CiteClear has limited support for non-U.S. legal citations. It can detect obvious formatting issues and malformed citations, but may not recognize all foreign court abbreviations or reporter systems. Always manually verify foreign citations.

What should I do with citations flagged as suspicious?

Treat suspicious citations as potentially invalid. Use the provided search links to attempt manual verification. If you cannot confirm the citation through authoritative sources, remove it or replace it with a verified source.

Does CiteClear make legal judgments?

No. CiteClear provides triage — it flags structural and pattern-based issues. It does not make legal judgments about the validity, precedent value, or applicability of any citation. Manual verification by qualified professionals is always required.

Can I verify citations from multiple AI outputs at once?

Yes. Paste all the citations from your AI output into CiteClear, separated by newlines. CiteClear will analyze all of them simultaneously, deduplicate as needed, and provide a comprehensive report.

Is there a limit to how many citations I can verify?

No. CiteClear's citation-only checker has no limit. You can paste as many or as few citations as you need to verify.

Can I save or export verification results?

Yes. After verification, you can copy the full report as markdown or download a CSV file for your records. Both formats include all the citations, their status, risk levels, and suggested actions.
