Bengo4.com Launches First Integrated AI Legal Research Tool Equipped with Legal Brain

Bengo4.com, Inc. (Minato-ku, Tokyo; Representative Director, President and CEO: Taichiro Motoe; hereafter “the Company”) is pleased to announce that it has launched the first integrated AI legal research tool equipped with Legal Brain.

■ What is Legal Brain?

With the increasing complexity of today's society, the scope of duties and amount of information necessary for lawyers and corporate legal departments are increasing. As a result, more time is spent on legal research, paperwork, legal checks, and similar tasks. Especially in corporate legal affairs, the Company is seeing issues with labor shortages and difficulties in hiring, and given the complexity of the knowhow required, post-recruitment training is time-consuming.

Considering this, since last year, the Company has been engaged in research and development with the aim of integrating AI and legal data.

Now, the Company has successfully developed the core technology, Legal Brain, with a built-in legal database called Legal Graph, a Bengo4.com proprietary product.

Legal Graph is a database that organizes considerable volumes of information as a network. This database is constructed by adding huge volumes of external data on laws and guidelines and huge volumes of internal data such as precedent data, information on legal books, legal consultation records, and information from lawyers that the Bengo4.com Group has accumulated over the years, graphing the relationships among individual data points. The core technology that incorporates generative AI into Legal Graph is Legal Brain. Using this makes it possible to realize legal services with unprecedented convenience.

■ What is an integrated AI legal research tool?

As the first product equipped with Legal Brain, Bengo4.com offers this integrated AI legal research tool that enables identification and organization of legal arguments and collection of information. Users need only enter the information they want to look up for the integrated AI research tool to conduct cross-sectional research on legal information by referencing laws, guidelines, precedent data, legal book data, legal consultations, public comments, and so forth, while also taking into account legal arguments. This reduces the time required for legal research work that involves the identification and organization of legal arguments and collection of information, achieving efficiency exceeding that provided by conventional legal research tools.
