Two new websites for lawyers and law students have similar purposes.
CaseText is a great idea, but as Bob Ambrogi points out, it will only work if people contribute to it. Of concern, of course, is who contributes to it. If lawyers with relevant experience annotate cases central to their practice areas, CaseText could be really valuable. If wacko conspiracy theorists mark up their favorite cases, it will be worthless.
LearnLeo just added a feature that allows law students to mark up cases to turn them into case briefs. The idea is to make it easy to brief cases. Unlike CaseText, annotations and highlights are not shared.
While LearnLeo’s system sounds useful, I don’t think it is a good idea for law students to shortcut their case briefing. Doing case briefs by hand (or summarizing them in whatever way is useful for you) is the best way to learn them.
