Real people asking for this
DA used AI to write her MILs and every case citation is FAKE
Looks like the DA going to trial with tomorrow used AI to write her motions because every case citation is FAKE. The DA no-showed after being confronted. Judge ordered DA present to explain. Public defender discovered it by simply checking the citations.
This isn't a one-off. Lawyers have been sanctioned, fined, and publicly humiliated for filing briefs with hallucinated citations. A New York attorney was fined $5,000 for citing fake cases generated by ChatGPT. A Colorado attorney faced disciplinary proceedings. The pattern is accelerating as more lawyers use AI for research without verification.
The existing legal research tools - Westlaw ($400+/mo), LexisNexis ($300+/mo) - are databases, not verification tools. They help you find real cases, but they don't check whether the citations in your brief actually exist. And the AI tools lawyers are increasingly using (ChatGPT, Claude, CoCounsel) generate plausible-sounding citations that may be entirely fabricated.
Build a verification layer. Lawyer writes or generates a brief. Paste it into the tool. AI parses every case citation - party names, volume, reporter, page number. Each citation is checked against actual court records (CourtListener API, Google Scholar case law, state court databases). Results: green checkmark (verified, with link to actual opinion), red X (citation does not exist), yellow warning (partial match, possible error in volume/page).
The tool doesn't replace Westlaw - it sits on top of any workflow. Write your brief however you want. Before filing, run it through the verifier. Takes 30 seconds. Prevents career-ending sanctions.
Price at $49/mo for solo attorneys, $99/mo for small firms (up to 5 users), $199/mo for mid-size firms. The value prop: one sanctions motion costs $5,000-50,000+ in fines, reputation damage, and malpractice exposure. $49/mo is insurance.
At 10,000 subscribers averaging $80/mo, that's $9.6M ARR. Expansion: add citation suggestion (find real cases that support the same argument), brief quality scoring, and jurisdiction-specific formatting checks.
Analysis and revenue estimates are educational. Results vary by execution and market conditions.
Quick breakdown
Solo attorneys, small law firms (1-20 lawyers), public defenders, and paralegals who use AI for legal research or brief drafting
Westlaw ($400+/mo, database not verifier), LexisNexis ($300+/mo, same), CoCounsel by Thomson Reuters ($100+/mo, AI research but no verification layer), manual checking (time-consuming, error-prone)
AI hallucination in legal briefs is a growing crisis. Sanctions are being issued. No tool specifically verifies citations exist. Every lawyer using AI needs this as a safety net. Massive willingness to pay to avoid career-ending mistakes.
