At a glance
What it does
Lexis+ AI is an AI legal research tool from LexisNexis, now marketed as Lexis+ with Protege. Lawyers ask legal questions in plain language and get answers backed by case law and statutes. It checks citations with Shepard's Citations and flags cases that are no longer good law, and it can draft motions, briefs, and other legal documents. It works with Microsoft 365 files and document systems like iManage and NetDocuments. LexisNexis holds SOC 2 and ISO 27001 certifications for its security program. The tool does not connect to law practice management software, so it works best next to a separate case management tool.
Where it can help
This fits a firm already using LexisNexis for legal research, from small firms to larger legal departments that read a high volume of case law. Base Lexis+ research plans start near $128 a month per user based on third-party pricing reports, with the AI layer normally a separate quote on top; treat both as planning estimates. A good starting point is adding the AI add-on to a few existing Lexis+ seats before a firm-wide rollout. Watch for two things: pricing is not fully public and reviewers describe it as an added cost on top of a base subscription, and like all legal AI, its drafts and case summaries need a lawyer's review before use in a filing.

Get started
What you need first
What you need firstSet up the basics
Confirm current product identity, commercial packaging, data processing terms, sign-in and access rules, retention, integrations, support model, implementation effort, and rollback conditions.
How to startSet clear limits
Verify identity, package, availability, ownership, pricing, and security evidence before approving a pilot
Before you scaleSet safe working rules
Recommended next action
Do not approve a pilot yet. Verify the current product identity, package, availability, owner, pricing, and security evidence; then define one workflow, a baseline, and rollback criteria.
Decision ownerBusiness and technology owner
STARTSet a goal and owner
Define what success looks like for a test of Lexis+ with Protégé (formerly Lexis+ AI) and assign someone to lead it.
FIRST MONTHTest one workflow
Once the requirements above are met, compare a small trial with how your team works today.
MONTH TWOReview actual use
Track adoption, output quality, business results, and actual costs against the estimate.
MONTH THREEDecide what comes next
Use the results to decide whether to stop, adjust, or expand the pilot.
Risk profile
Required controls
Security and safe use
Confirm encryption, how the vendor uses your data, customer data separation, how long data stays and how to delete it, activity records, sign-in and user setup, where data is handled, other companies that process data, past incidents, and what your team must manage.
Exit and rollback
Export executed documents, matter links, clause libraries, playbooks, redlines, obligations, approvals, citations, review history, and audit evidence from Lexis+ AI. Preserve privilege and document-to-metadata relationships during export; trained review behavior may not transfer, so validate active matters and obligation continuity before cutover.
Recommended next step
Do not approve a pilot yet. Verify the current product identity, package, availability, owner, pricing, and security evidence; then define one workflow, a baseline, and rollback criteria.
