Lexis Launches Protégé Work, Expands Offering

LexisNexis has expanded its Lexis+ AI platform with Protégé Work, along with a new definition of its LLM-based offering as the ‘foundational infrastructure for legal AI’, plus a raft of improved capabilities (see below).

In terms of ‘Work’, you can ‘select a skill directly or describe a legal goal in natural language. Protégé intelligently routes the request to the appropriate skill or workflow’.

I.e. this is not just a one-shot prompt on the side of one’s work, it’s a multi-faceted system that is wholly integrated into the LexisNexis experience.

As they explained: ‘Instead of generating a single response, Protégé presents a structured plan for the work, giving users visibility and control as it executes tasks and produces review-ready legal work product.

‘Skills support repeatable tasks such as contract comparison, complaint analysis, research synthesis, checklist generation, due diligence, compliance review and playbook-based review.

‘This allows legal teams to reuse proven workflows, apply firm and department standards consistently, and benefit from broader market innovation while keeping work grounded in authoritative LexisNexis content, firm knowledge and trusted workflow safeguards.’

Plus, they added that Lexis+ with Protégé incorporates LexisNexis-developed and Anthropic-powered skills.

They also underlined that LexisNexis is now looking at what their legal AI capabilities can do as foundational infrastructure. I.e. that, as noted, it’s not about dipping in and out occasionally into an LLM with a prompt, but rather having a new AI architecture running all the way through LexisNexis that connects to skills, their curated data, and workflows.

Sean Fitzpatrick, CEO, LexisNexis Global Legal, commented: ‘Legal AI must do more than produce plausible answers. It must produce work that lawyers can verify, defend and trust. Lexis+ with Protégé brings together the content foundation, workflow intelligence, security and model flexibility legal professionals need to use AI at scale without compromising the standards of the profession.’

As well as Work, they highlighted:

• ‘Protégé Agentic Drafting, which helps lawyers and legal teams produce review-ready work product in minutes.
• Outputs from Protégé Skills can be delivered in the formats legal teams already use every day. This includes Microsoft Word for drafts, Excel for review tables and structured findings, PowerPoint for client-ready summaries, and PDF for polished, ready-to-use work product.
• Protégé Workrooms extends legal AI into secure collaboration. Law firms, corporate legal departments and counsel can work together in private, permission-aware spaces where documents, drafts, analysis and AI workflows are shared only as authorized.
• Shepard’s Verify Trust Markers bring LexisNexis’s trusted citation authority directly into AI-assisted work. The capability identifies legal citations in AI-generated and attorney-drafted content, checks them against LexisNexis authoritative legal sources, and flags citations that cannot be verified as existing.
• And a reimagined Protégé Vault gives legal professionals a secure intelligence layer for large, complex matters. Teams can analyze documents, PDFs, spreadsheets, images, audio, video and other matter materials in one workspace, with support for up to 100,000 documents per Vault. Outputs link back to source material including exact document passages, spreadsheet rows, images or timestamps so legal teams can verify findings and defend the work product that follows.
• As well as Protégé BYOK, which gives enterprise and government customers additional control over sensitive information. With Bring Your Own Key encryption, customers can manage their own encryption keys through their chosen key management service and revoke access when required, supporting the data-control expectations of law firms, regulated industries and public-sector legal teams.’

All in all, not just new capabilities, but a larger reframing of what is now possible with their legal AI.

The battle to provide the most comprehensive – and super-useful – legal AI platform continues.
