Legal research company Casetext has raised $12 million in a new round of funding.

The money will be used to expand its software platform that offers insights into cases cited in legal documents and to further develop CARA (Case Analysis Research Assistant), an AI-powered assistant for lawyers.

Using natural language understanding, Casetext scans the text of legal briefs to locate and analyze case citations. The company also offers access to 10 million court cases and statutes annotated by a community of litigators.

The $12 million funding round was led by Canvas Ventures, with participation from Union Square Ventures, 8VC, and Red Sea Ventures. The company previously raised $7 million in a 2015 funding round led by Union Square Ventures.

Casetext isn’t the only legal service driven by AI and natural language understanding.

Last year, law firm BakerHostetler began to work with legal bot ROSS.

And last October, a group of legal and computer science professionals made an AI judge that was nearly 80 percent accurate in its assessment of cases heard by the European Court of Human Rights.

There’s also Visabot for help with visa forms, and DoNotPay, which has helped people challenge hundreds of thousands of parking tickets. Like Casetext, both Visabot and DoNotPay were made in Palo Alto, Calif.
