Litera Connects Firm Intelligence to ChatGPT Enterprise with Foundation

In ChatGPT, users can ask strategic questions about what their firm knows, which experience is most relevant, and who has the right experience and relationships for a new opportunity. Responses are grounded in the Foundation records each user is permitted to access.

Litera brings 30 years of legal expertise, Foundation's legal-specific data model, and each firm's own governed experience and relationship records. Foundation Firm AI Search connects those strengths, meeting lawyers in ChatGPT while keeping Foundation as the source of firm intelligence.

Foundation customers use that intelligence to support more responsive client service, faster and more accurate RFP responses, and new revenue opportunities. When users need supporting records, citations, record links, or deeper workflows, they continue in Litera or Foundation.

Frontier Intelligence Meets Firm Intelligence for Legal AI

"Frontier intelligence becomes more useful when connected to a firm's own experience and relationships," said Grant Hewlett, VP, Product for Firm Intelligence, Litera. "OpenAI brings the reasoning. Foundation brings what a firm has done, who led the work, or how its client relationships connect. For years, many of the world's leading law firms have relied on Foundation to organize their most strategic experience and relationship knowledge. Bringing Firm AI Search plugin in ChatGPT makes that firm intelligence accessible through a prompt, grounded in the Foundation records each user is permitted to access, so firms can put it to work on the next client opportunity."

A lawyer responding to an RFP can ask, "Show me our most relevant pharmaceutical IP litigation experience for this RFP," and receive a response grounded in the Foundation records they are permitted to access.

"We believe the next generation of AI for law will be built around what makes each firm distinctive - its expertise, judgment, and way of working. By building alongside Litera, we're turning that expertise into AI lawyers can use every day, creating new ways for firms to serve their clients and shape the future of legal work." - Jason Boehmig, GM Legal Industry at OpenAI
