Legal-AI Assistance
With the surge of advanced large language models and generative AI, a new category of solutions have emerged that are aimed at improving processes through automation. Legal AI Assistants typically address multiple use cases or perform a variety of "skills," similar to a human legal assistant. AI legal assistants sometimes focus on a particular area of practice or set of use cases, while others offer generic legal skills that can be leveraged by multiple practice areas.
