MotionValidator performs a complete brief audit in four areas: (1) Case law verification—confirming cases exist, are binding in your jurisdiction, haven't been overturned, and actually support your proposition; (2) Statutory verification—checking statutes exist, are still in force, and are correctly applied; (3) Procedural intelligence—identifying court-specific rules, deadlines, and local requirements for your motion type; (4) Formatting compliance—verifying margins, fonts, spacing, page limits, and exhibit requirements match your court's rules.

Traditional citators check if a case is "good law"—whether it's been overturned or distinguished. MotionValidator goes further: we verify whether the case actually supports the proposition you claim it does. A case can be perfectly good law and still be misapplied. That's the gap where lawyers get sanctioned, and it's what we're designed to catch.

Yes. We strip personally identifiable information before processing, encrypt everything at rest and in transit, and never train our models on your data. Documents auto-delete after seven days. We built this for litigators who understand confidentiality isn't optional.

After verification, you receive a Citation Verification Report—a court-ready document listing every citation checked and what was verified. Each citation shows its verification status (existence in official sources, current treatment, propositional alignment, and jurisdictional relevance). For courts concerned about AI-generated filings, it's evidence of rigorous process. For your practice, it's documentation the work was done right.

MotionValidator is built on a replica of the Free Law Project/CourtListener corpus—10.5 million cases across all U.S. jurisdictions. When you upload a motion, every citation is checked against this database in real-time. We're not guessing if a case exists; we're querying the same comprehensive case law repository used by legal researchers nationwide. MotionValidator is a full citator built on verified legal data.

Our citator uses intelligent jurisdiction walking. Starting from the court in your motion, we automatically check the entire appellate chain up to the Supreme Court, plus strategically important lateral jurisdictions (like the Federal Circuit for patent matters, or relevant federal circuits for state appellate courts). This ensures we catch adverse treatment wherever it might appear—not just in the obvious places, but in the jurisdictions that could actually affect your case.

Currently 6,000 words, which accommodates standard motions in most U.S. courts. We'll extend this limit over time, but this covers the vast majority of trial-level and appellate briefs.

PDF and DOCX. Your formatting is preserved throughout the process. You may also paste a draft in plain text or markdwon straight from a word processor or your chosen AI tool.

Yes. Many users find this our most valuable feature—finding where opponents have stretched the truth.

Yes—and many of our test users find this our most exciting feature. Upload their motion and get the same comprehensive audit. If they've used hallucinated cases, stretched a holding, misapplied a case, or cited overturned authority, you'll know in minutes.

Yes. After validation, switch to Editor mode and refine your brief without leaving the platform. Our AI assistant was developed with leading litigators—every suggestion is shaped for legal precision, persuasive advocacy, and appropriate tone. You can highlight specific passages for targeted improvements, or use the chat function to revise entire sections.

Not currently. MotionValidator focuses on primary authorities—case law, statutes, and procedural rules—because those are what courts rely on and where errors have consequences.

Exhibits are excluded from verification. We focus on the brief itself—the arguments, authorities, and procedural compliance that directly impact the motion's success.

Any single brief up to 6,000 words. The word limit ensures thorough verification without compromising processing speed.

Our commercial strategy has not yet been finalized, but this is something we are considering.

MotionValidator is built on the same citation verification framework that outperformed Westlaw's Deep Research AI in legal accuracy tests. In November 2025, Thomson Reuters tested their system with a simple question about laboratory directors as expert witnesses. Westlaw's AI confidently gave the wrong answer. Our framework correctly distinguished the holding from the rule—catching exactly the kind of subtle misapplication that ruins arguments.

No matter what verification tools attorneys use; your work is always your responsibility when filing. We just make that process easier for you. Every conclusion MotionValidator makes is rooted in the actual text of a cited case, and we link you to the full text of each case so you can verify for yourself. Every conclusion shows you the exact text from a case that allowed MotionValidator to reach that conclusion.

MotionValidator is a product of Citational, an AI research lab dedicated to law. We build verification infrastructure, not chatbots. Our team includes litigators and senior technologists. People passionate about law who understand the day-to-day work of attorneys, and what courts actually need, as well as AI researchers focused on reliability over speed.

You shouldn't trust AI alone—which is why MotionValidator isn't just AI. Every case citation is verified against our replica of the Free Law Project database. Every statute is checked for current force. Every procedural rule is pulled from official court sources. The AI reads and analyzes (including reading the full text of each cited case, not just relying on an LLM's trained "weights"), but the verification happens against real data, not language model outputs.
