LexisNexis AI Pricing With Lexis AI Cost, Lexis+ AI Pricing and the $99 to $250 LexisNexis Charges for Each AI Request

What does LexisNexis charge for each AI request?

LexisNexis publishes transactional list prices for everything on its platform, and since January 2026 the Large Legal schedule has a section for Lexis+ with Protege. A Generative AI Ask costs 99 dollars. A Generative AI Summarize costs 250 dollars, and so does a Generative AI Drafting request. Uploading a document and asking a question about it costs 12 dollars; uploading a document and asking for a summary costs 250. A prompt the assistant does not support costs nothing.

The older Law Firm Per Search schedule, effective December 5, 2023 and still posted, carries the same Lexis+ AI figures: 99 dollars an Ask, 250 dollars a Summarize, 250 dollars a Drafting request, 12 dollars a Document Upload and Ask. The rates have not moved in more than two years.

These prices apply to materials used outside your subscription. Both schedules say so in the same words: the list prices "will not affect the price of your flat rate subscription but do apply to Materials used outside of your subscription." If your contract includes Protege, a question you ask inside it is covered. If it does not, or if your plan scopes the assistant narrowly, each request is priced on this list.

How much does Protege cost per month?

For law firms of one to three attorneys, Protege Assistant with Lexis Complete is 495 dollars per attorney per month on a three year term, or 660 on one year, and Protege Firm Documents with Lexis Complete is 595, or 793, on the store version LexisNexis began testing in October 2026. The other monthly figure LexisNexis attaches to Protege is on its Nexis store, which sells business research rather than case law. Read on September 22, 2026, at one seat on a one year subscription length, Nexis Essential costs 342 dollars per seat per month, Nexis+ with Protege Essential costs 935 dollars and Nexis+ with Protege costs 1,130 dollars. The assistant therefore adds 593 dollars per seat per month on the Nexis side.

Nexis and Lexis+ sell different content to different buyers, so 593 dollars is an anchor rather than a law firm quote. It is still useful in a negotiation: it is what LexisNexis itself decided the assistant is worth on a product where it had to print a price.

Thomson Reuters prints its equivalent for law firms. Westlaw Advantage with CoCounsel Essentials costs 71.50 dollars a month more than Westlaw Advantage alone at all states and federal on a three year term, and 126.75 dollars at single circuit. Westlaw Edge with AI-Assisted Research costs 85.15 dollars a month more than plain Westlaw Edge at all states and federal on three years. Those are the numbers to bring to a Protege quote.

Is LexisNexis AI worth it for a small firm?

It is worth pricing if you draft and summarize heavily and already live inside Lexis+. At 250 dollars per out-of-plan summary, a firm that summarizes a few documents a week is far better off with Protege inside the subscription than paying per request, and that price is 495 dollars or more per attorney per month on the new store version for firms of one to three attorneys, or a quote otherwise. The Stanford RegLab study measured Lexis+ AI, the predecessor, at 65 percent accuracy with a 17 percent hallucination rate, better than the Westlaw tool it tested. Nobody has independently measured Protege yet.

It is harder to justify when the job is narrower: finding the decisions that control a question and checking that they still stand. For that, an AI tier from 495 dollars per attorney per month on a multi-year contract is a lot of commitment, and a single out-of-plan answer at 99 dollars costs twice a month of a research tool with a published price.

CaseSearch answers that narrower question directly. You ask in plain English and get the on-point decisions with citations, the holding in plain language and a good-law signal, for 49 dollars a month month to month or 24 a month billed yearly, with no seat minimum and no per-question charges. It does not replace Shepard's, Lexis+ secondary sources or Protege drafting, and a firm built on Lexis should keep Lexis. For the everyday research question, it is a price you can see before you buy.
