LexisNexis Protege Pricing Covering Lexis+ with Protege Cost per User and the One Protege Price LexisNexis Actually Publishes

How much does LexisNexis Protege cost?

For a law firm of one to three attorneys, LexisNexis now publishes an answer on a store version it began testing in October 2026. Protege Assistant with Lexis Complete is 495 dollars per attorney per month on a three year term, with the one year price of 660 struck through beside it, and Protege Firm Documents with Lexis Complete, flagged Most Popular, is 595, or 793 on one year. Both include comprehensive research, Shepard's, Practical Guidance and Forms, CourtLink and Protege Ask, Summarize and Drafting, and the Firm Documents package adds upload of your own documents, Vault and Create+. Some visitors still get the older page, where the Lexis+ with Protege row says "Pricing on request" and puts a free trial button where the other four plans put a subscribe button, and firms of four or more attorneys still request pricing.

The four tiers without the assistant, Essential at 114 dollars, Deluxe Transactional at 217, Enhanced at 257 and Professional at 324 per attorney per month on a three year term, set the baseline. Protege Assistant at 495 is 171 dollars a month above Professional on a three year term, and 228 above it on one year, 660 against 432.

A second number comes from the other side of the same company. LexisNexis sells Nexis+ with Protege through its own store, self-serve, to business users buying one to five seats. Nexis Essential, the same news and search product with no assistant, is 342 dollars per seat per month. Nexis+ with Protege Essential is 935. The full Nexis+ with Protege build, which adds company and financial data, is 1,130. Subtract the base product and LexisNexis is charging 593 dollars per seat per month for Protege and the AI features that come with it.

Treat that as a ceiling-ish anchor rather than a quote. Nexis content is priced for corporate research teams and Lexis+ content is priced for lawyers, and a law firm quote will be built from your jurisdiction, your seat count and your term length before anyone talks about the assistant. But when a sales rep tells you Protege is a modest uplift on your existing Lexis+ line, the Nexis price says the uplift can be larger than the base subscription.

What is LexisNexis Protege?

Protege is the LexisNexis AI assistant for legal and business professionals, described in the LexisNexis help documentation as the next generation of Lexis+ AI technology and a virtual AI assistant designed for legal professionals. It sits inside the platform you subscribe to, answers questions against LexisNexis content and your own uploaded documents, drafts, summarizes and compares, and grounds its verification in Shepard's.

The 2026 release is built around workflows rather than a chat box. LexisNexis shipped more than 300 pre-built configurable workflows at launch, added a no-code builder so firms can assemble their own, and sells a white glove workflow service for firms that want them built for them. Advanced practice-area workflows and agentic and persona workflows are on the published roadmap rather than in the product today. Underneath it runs what LexisNexis calls a living legal knowledge graph, which it describes as more than 200 billion interconnected documents taking in four million new documents a day, and it routes to general models from Anthropic, Google and OpenAI.

For a solo or a small firm, the honest read is that most of that machinery is priced for an enterprise buyer. If your day is finding the controlling case, reading the holding and confirming it is still good law, you are being quoted for a drafting and workflow platform in order to get a research assistant. That mismatch, not the technology, is why so many small firms price Protege and then buy something narrower.

How accurate is LexisNexis Protege?

Nobody has published an independent measurement of Protege itself. The study everyone quotes, the Stanford RegLab work published in the Journal of Empirical Legal Studies, tested Lexis+ AI and Westlaw AI-Assisted Research, and found Lexis+ AI accurate on 65 percent of test queries with a 17 percent hallucination rate against 42 percent and 33 percent for Westlaw. Lexis+ AI is the product Protege replaced, so those numbers describe the predecessor.

That matters more than it sounds. A vendor claim that its AI is grounded in authoritative content is a statement about the corpus, not about the answer. Grounding reduces invented citations, it does not eliminate them, and the RegLab result on the best-scoring product in the study was one wrong answer in three. Every sanctions order in the last two years followed the same sequence: an AI answer, a citation that looked right, and no human opening the case.

So the buying question is not which vendor has the lowest hallucination rate. It is which product makes verification fast enough that you actually do it on every authority. A tool that puts the citation, the holding and the treatment signal in front of you, with the citing opinions one click away, gets checked. A tool that hands you a polished memo does not.

What the LexisNexis store makes easy to misread

Three things, and all three cost money. The first is the term. The store shows the three year rate as the headline figure with the one year price struck through beside it, the way a retailer shows a sale. Essential looks like a 114 dollar product and is a 114 dollar product only across 36 months. For twelve months it is 152. A two year term takes 10 percent off and a three year term takes 25 percent.

The second is the jurisdiction gate. The store will not price anything until you pick a state, and the entry tier is a single-state product with no federal caselaw at all. Federal reporters start at Enhanced, which is 257 dollars on three years or 342 on one. A litigator who buys Essential to keep the line item small and then catches a removal has a subscription that does not reach the material.

The third is who is allowed to buy. The seat selector stops at three attorneys and then reads "for 3+ seats, contact us", and the page carries a line saying the promotional prices are for new customers only. So the published rate card is a new-customer, small-firm, long-term offer. If you are renewing, or you have four lawyers, none of the numbers on the page are yours.
