Leverage powerful AI to
 change the way you practice
In an era where anything can be “googled,” legal research is still one of the most time-consuming and expensive tasks for most lawyers. Casetext set out to solve this problem by leveraging transformer-based neural nets, a pioneering form of AI.
The result is Parallel Search, the efficient and effective legal research tool that brings legal research up-to-speed. And just like Google, Parallel Search is 100% free.
Modern search technology 
that finds cases Lexis and Westlaw miss
Traditional search technology matches queries with cases based on words and synonyms. That only gets you so far in legal research, where arguments are based on concepts and analogies.
Parallel Search is the modern search technology you can’t find anywhere else. Using advanced AI, Parallel Search finds on-point authorities that are conceptually similar to a sentence, retrieving more accurate results faster.
Skip the tricky Boolean
No need to waste time trying to formulate Boolean queries. Search an argument from your brief and get on-point law without the hassle.
Go beyond keywords
Keyword searches limit results to literal keyword matches. Parallel Search understands concepts, so you’ll find relevant cases you’d otherwise miss, not just matching keywords.
Get better results faster
Quickly find the authority you need for statements you know to be true, without getting the extraneous, irrelevant case law.
