CiteProof tool checks AI-hallucinated citations in lawyers' briefs

A new service called CiteProof scans legal briefs for fabricated case citations and misquoted court opinions generated by AI. Checking a single brief costs $49, a five-pack is $199, and a subscription for 200 reviews runs $499 per month. The tool uses no AI, relying instead on deterministic searches of public court records.

• Single brief check costs $49; five-pack is $199
• Law firm subscription: $499/month for 200 brief reviews
• No LLMs used — only deterministic searches via CourtListener
• Prompted by AI-fabricated citations, including a vacated Georgia court decision
