AI Legal Research
Legal research where every citation is read, not assumed.
LitigusAI is an AI legal research platform built for litigators. Research runs against the Litigus Library, LitigusAI's own collection of more than 10.8 million opinions from more than 2,100 Federal, State, territorial, and specialty courts, searchable by meaning and by legal proposition, together with federal statutes, regulations and court rules, and the statutes of all 50 states and the District of Columbia. Dozens of searches run at once, so research that would take an afternoon runs in minutes, and every citation in delivered work is checked against the opinion itself before it reaches you.
Why it is different
Research that carries the whole case with it.
One continuous understanding of the matter
Research tools answer only the question in front of them, with no memory of the matter behind it. LitigusAI works from the client file on your computer, so every search starts from the facts, the posture, and the work already done.
10.8 million opinions, updated daily
The Litigus Library covers more than 2,100 Federal, State, territorial, and specialty courts, with search by meaning and by legal proposition. You search the law the way you think about the case, not the way a keyword box demands.
Dozens of searches at once
Purpose-built infrastructure fans a research question out into dozens of targeted searches and pulls the results together in minutes instead of an afternoon.
Every citation verified
LitigusAI reads each cited opinion and confirms it says what the work product says it says. The verification happens before delivery, not after embarrassment.
Your files never leave your device
Research runs under a strict zero-data-retention policy. No client document is stored on LitigusAI hardware, and nothing is used to train any model.
Questions
Asked and answered.
Is LitigusAI a replacement for Westlaw or Lexis?+
LitigusAI is not a browser-based research terminal. It is a desktop AI associate that does the research as part of the assignment. It reads the file, runs the searches, and delivers cited, verified work product. Research happens inside the work, not in a separate tab.
How current is the law library?+
The Litigus Library holds more than 10.8 million opinions from more than 2,100 Federal, State, territorial, and specialty courts, and it is updated daily.
Can I trust the citations?+
Every citation in delivered work is checked by reading the opinion itself. As with any associate's work, you review and verify before anything is filed.
What happens to my client's data during research?+
Your files stay on your machine. Model requests run under a strict zero-data-retention policy, and nothing is retained or used to train a model.
