Today Casetext announced a $7 million raise led by Union Square Ventures for its site which crowdsources legal commentary. Casetext’s model is not entirely unlike Rap Genius — now just “Genuius” — which calls for experts to annotate various texts, including rap lyrics.

Palo Alto, California-based Casetext says its new round will be used to “expand its legal database and enhance its platform as it builds toward becoming the best resource for reading and sharing legal commentary online.”

The two-year-old company’s $7 million raise follows an earlier $1.8 million seed round from SV Angel, Box Group, and others.
