As I’ve transitioned into a new area of law, Clio Work has been tremendously valuable.

AI legal research software FAQs
What is legal research software?
Legal research software helps lawyers find and analyze the law that applies to a matter, including case law, statutes, regulations, procedural rules, and legal commentary. Better tools go beyond search, showing which passages courts cite most and whether a case is still good law. Clio does this from a library of more than 1 billion legal documents. Get a demo.
What’s the best AI legal research software?
Look for AI legal research software that cites its sources, so each answer can be checked against the passage it came from, and that works from a dedicated legal library rather than the open web. Clio’s AI draws on more than 1 billion legal documents, and its citation signals show how each case has been treated. Get a demo.
What sources does Clio’s legal research include?
Clio’s legal library includes case law, statutes, regulations, procedural and practice rules, and legal commentary from more than 2,500 data sources across over 100 countries, including exclusive partnerships. New documents are added daily. Start a free trial.
How do I know if a case is still good law?
Clio uses citation analysis and color-coded signals to show whether a decision has been upheld, questioned, or overturned. It also highlights the passages courts cite most often and alerts you when a statute or regulation you rely on is amended, so you can confirm the authority before you cite it. Get a demo.
Can I see how a statute read at a specific point in time?
Yes. View legislation as it existed at any point in time, along with its historical versions, so your analysis reflects the law as it stood when it mattered to your case. A precedent timeline also shows how courts have applied a legal principle over the years. Get a demo.
Can I compare laws across jurisdictions?
Yes. Browse by jurisdiction, court, or practice area, and view multiple laws side by side in one view. Primary law from over 100 countries sits in the same library, so a comparison doesn’t mean switching tools. Get a demo.
What’s the best legal research software for small law firms?

Look for case law, statutes, and commentary in one place, signals that show whether a case is still good law, and alerts when the law changes. Clio Work is built for small and mid-sized firms, with research connected to your matters. Start a free trial.
Can I connect legal research to my matters?
