vLex (Fastcase) Unveils Beta Version Of Its Global, Multi-Language Generative AI Legal Research Tool

The Vincent AI Legal Research Assistant allows users to access the corpus of vLex documents through natural language searching. The suite uses a mix of AI tools and LLMs, including OpenAI’s GPT-4 and GPT-3.5, as well as some proprietary AI tools built by vLex.

The Vincent AI suite includes the following:

  • Ask a Question allowing users to answer legal questions and create research memos by inputting a question in natural language, rather than traditional Boolean search strings
  • Build an Argument allows users to build a thorough legal argument, either for or against a stated proposition, again based solely on precedent from designated sources or jurisdictions within the vLex database.
  • Compare Law in Different Jurisdictions—allows for forum-shopping or comparing governing law across different states or countries
  • Spot Legal Issues—read and summarize issues in a case
  • Headnote Summaries—create on-the-spot editorial headnotes for cases
  • Document as a Search—drag and drop a document to automatically find related precedents without additional searching
  • Related Authorities—find related primary and secondary authorities from vLex during research
  • Vincent for Word—access Vincent AI from within a Microsoft Word draft

Limiting the responses to just the vLex database, or even further to chosen sources from within that database, is a process called retrieval augmented generation (RAG). RAG constrains answers to the four corners of the legal authorities a user has selected, and it eliminates hallucinations.
