Lex Machina

Lex Machina is a legal analytics platform offering data-driven predictions on judge rulings, motion outcomes, and case strategy. It provides the deepest judge-level analytics available with historical motion success rates, profiling every federal district with party and attorney information. The platform integrates directly with LexisNexis, making it a natural fit for firms already embedded in that ecosystem. On the downside, enterprise pricing can be prohibitive for solo practitioners, and state court coverage is more limited compared to federal. If you handle significant federal litigation, Lex Machina gives you the richest data set to work with.

The platform calculates win rates by judge, court, and case type for every attorney, making it invaluable when you need to evaluate opposing counsel or decide whether to take on a case in an unfamiliar jurisdiction.

Pre/Dicta

Pre/Dicta is a litigation intelligence platform that classifies 20M+ cases to predict motion and case outcomes.

Casetext (CoCounsel)

Casetext (CoCounsel) is an AI legal research assistant that surfaces persuasive authorities and estimates litigation angles. Unlike the pure analytics platforms above, CoCounsel focuses on automating document review and legal research, completing in minutes what traditionally takes hours. Acquired by Thomson Reuters, it benefits from deep data resources and long-term platform stability. At $99 per month, it is significantly more affordable than enterprise analytics tools. However, it is not purpose-built for outcome prediction and is more research-focused, and state court coverage varies by jurisdiction.

It claims the highest domain-specific accuracy in its niche, but it is limited to tax and employment practice areas only.
