Review: vLex’s Vincent AI

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 large language models (LLMs), including OpenAI’s GPT-4 and GPT-3.5, as well as some proprietary AI tools built by vLex,

“Vincent AI is now the only tool on the market that can build arguments and answer research questions in different jurisdictions, using verified, customizable sources to ensure responsible, ethical, and accurate performance.”

Robin Chesterman, global head of product at vLex

One main feature, called Ask a Question, allows users to answer legal questions and create research memos by inputting a question in natural language, rather than traditional Boolean search strings.

Vincent AI then conducts research in primary and secondary sources in the jurisdictions chosen by the user, then presents a summary of the research results, accompanied by a list of verified sources with links directly to the source documents. For U.S. law, the citations are verified by Fastcase’s new Cert citator. From the list of presented sources, the user can narrow down to a smaller selection if they so desire, and the produced summary will be limited to only those sources.
