The expansion, announced today, layers six new or expanded components onto the platform. The expanded components are:<\/p>\n
- \n
- Prot\u00e9g\u00e9 Work, a skills-and-orchestration layer that the company says is the centerpiece of the release.<\/li>\n
- Prot\u00e9g\u00e9 Agentic Drafting, purpose-built drafting agents for contracts, motions, briefs and deal documents.<\/li>\n
- Prot\u00e9g\u00e9 Vault, now supporting up to 100,000 documents per Vault and accepting audio, video and image files in addition to text.<\/li>\n<\/ul>\n
The features that are entirely new in this release are:<\/p>\n
- \n
- Prot\u00e9g\u00e9 Workrooms, secure collaboration spaces shared among firms, clients and co-counsel.<\/li>\n
- Shepard\u2019s Verify Trust Markers, a citation-checking layer that flags AI-generated or attorney-drafted citations that cannot be verified against LexisNexis sources.<\/li>\n
- Prot\u00e9g\u00e9 BYOK, a Bring Your Own Key encryption capability that LexisNexis says has already been deployed in AmLaw 100 firms.<\/li>\n<\/ul>\n
The release also adds standard-format outputs \u2014 Word, Excel, PowerPoint and PDF \u2014 for work product produced through Prot\u00e9g\u00e9 Skills.<\/p>\n
Taken together, the changes appear to add up to a significant platform-level shift, particularly in the move from a workflow library to an agentic framework that can plan and execute multi-step work \u2013 which the company describes as the centerpiece of the release.<\/p>\n
\u201cLegal AI must do more than produce plausible answers,\u201d LexisNexis Global Legal CEO Sean Fitzpatrick said in a prepared statement. \u201cIt must produce work that lawyers can verify, defend and trust.\u201d<\/p>\n
From Workflows to an Agentic Framework<\/strong><\/h3>\n
What LexisNexis is calling the centerpiece of today\u2019s release is in Prot\u00e9g\u00e9 Work.<\/p>\n
When LexisNexis launched the commercial preview in January<\/a> and the general-availability replacement of Lexis+ AI in February<\/a>, the company described the product\u2019s core value as its more than 300 pre-built workflows, plus a no-code builder for customers to create their own.<\/p>\n
Today\u2019s release builds on that workflow library but extends it into an agentic framework that can plan and execute multi-step legal work, the company says.<\/p>\n
In practice, according to the release, users can either select a skill directly or describe a legal goal in natural language, and Prot\u00e9g\u00e9 will route the request to the appropriate skill or workflow, present a structured plan before executing, and then produce review-ready work product.<\/p>\n
Skills cover repeatable tasks such as contract comparison, complaint analysis, research synthesis, checklist generation, due diligence, compliance review and playbook-based review. This is much the same task universe described in earlier releases, but now wrapped in an orchestration layer that breaks a request into a visible plan rather than a single response.<\/p>\n
LexisNexis says the platform incorporates both LexisNexis-developed and Anthropic-powered skills, with additional skills planned over time.<\/p>\n
(Although today\u2019s release mentions only Anthropic by name, it says there has been no change in its relationship with the companies that provide other AI models, such as Google and OpenAI. \u201cLexisNexis integrates the best technology from the best providers to deliver value for our customers,\u201d a spokesperson said.<\/p>\n
Agentic Drafting and Multiple Formats<\/strong><\/h3>\n
Prot\u00e9g\u00e9 Agentic Drafting, which LexisNexis describes as a significant expansion of existing drafting capabilities, is a set of purpose-built drafting agents for contracts, motions, briefs and deal documents.<\/p>\n
According to the release (I have not yet seen any of this), drafts are grounded in LexisNexis content, firm templates, prior work and matter materials, and can reflect an organization\u2019s preferred style, apply vetted exemplars, preserve formatting and surface risk considerations before the work goes out.<\/p>\n
While this sounds similar in some respects to drafting capabilities offered by competitors such as Harvey, Spellbook, Legora and DraftWise, LexisNexis emphasizes that these capabilities are grounded in its own content library and the firm\u2019s own materials.<\/p>\n
The release also expands the formats in which Prot\u00e9g\u00e9 delivers work product. Outputs from Prot\u00e9g\u00e9 Skills can now be produced in Microsoft Word for drafts, Excel for review tables and structured findings, PowerPoint for client-ready summaries and PDF for polished work product.<\/p>\n
Workrooms: A Move into Collaboration<\/strong><\/h3>\n
Among the entirely new components in today\u2019s release is Prot\u00e9g\u00e9 Workrooms, which extends Prot\u00e9g\u00e9 into shared collaboration.<\/p>\n
According to the release, law firms, corporate legal departments and outside counsel can work together in private, permission-aware spaces in which documents, drafts, analysis and AI workflows are shared only as authorized, with dual approvals, least-privilege access, role-based permissions and audit trails.<\/p>\n
Arguably, this could place LexisNexis within territory occupied by collaborative deal- and matter-room products such as Litera Transact, HighQ and Legatics, although the emphasis here is on AI-assisted work rather than transaction management.<\/p>\n
Shepard\u2019s Verify<\/strong><\/h3>\n
Also new in today\u2019s release is Shepard\u2019s Verify Trust Markers, which LexisNexis describes as bringing its citation authority directly into AI-assisted work.<\/p>\n
The capability identifies legal citations in both AI-generated and attorney-drafted content, checks them against LexisNexis authoritative sources, and flags citations that cannot be verified as existing.<\/p>\n
![\"\"](\"https:\/\/i0.wp.com\/www.lawnext.com\/wp-content\/uploads\/2026\/05\/LN_Media_Shepards-Verify_VF82-1024x576.png?resize=1024%2C576&ssl=1\" "\\"\\"")
<\/a><\/p>\nNotably, the capability is described as confirming that \u201ccited authority exists and is retrievable.\u201d That suggests that it is not capable of confirming that a cited authority actually supports the proposition for which it is cited \u2013 which is a common failure in AI hallucination cases.<\/p>\n
Even so, for lawyers worried about the steady drumbeat of AI hallucination sanctions, embedded citation verification at the point of drafting is a meaningful safeguard, and the timing is notable. The release lands not long after the California State Bar published its proposed rule that would require lawyers to verify every AI output<\/a>.<\/p>\n
To the extent rules like California\u2019s spread, capabilities such as Shepard\u2019s Verify shift from useful safeguards to something closer to essential compliance infrastructure.<\/p>\n
An Expanded Vault<\/strong><\/h3>\n
Prot\u00e9g\u00e9 Vault, which previously existed as a secure document workspace within Prot\u00e9g\u00e9, has been significantly expanded, according to the release, to support up to 100,000 documents per Vault and to handle PDFs, spreadsheets, images, audio, video and other materials in a single workspace.<\/p>\n
Outputs link back to source material for verification, including to exact document passages, spreadsheet rows, images or timestamps.<\/p>\n
Notably, the 100,000-document ceiling, combined with the move into multimodal materials including audio and video, gives Vault the document-volume that legal teams need for substantial litigation and transactional matters.<\/p>\n
BYOK and Enterprise Trust<\/strong><\/h3>\n
Prot\u00e9g\u00e9 BYOK, also new, allows customers to manage their own encryption keys through their chosen key management service and to revoke access when required.<\/p>\n
According to the release, LexisNexis integrates directly with AWS KMS, Azure Key Vault, Google Cloud KMS and HashiCorp Vault, encrypting all customer data at rest using customer-controlled keys.<\/p>\n
The company says BYOK has been \u201cdeployed in AmLaw 100 firms\u201d following extensive testing.<\/p>\n
Content As Differentiator<\/strong><\/h3>\n
Following today\u2019s U.S. launch, LexisNexis says the expanded Lexis+ with Prot\u00e9g\u00e9 will roll out globally throughout 2026.<\/p>\n
As noted earlier, the release is the latest in a rapidly developing string of platform announcements from LexisNexis over the past five months, starting with the workflow preview in January, the consolidation and rebrand from Lexis+ AI to Lexis+ with Prot\u00e9g\u00e9 in February, and now today\u2019s expansion.<\/p>\n
