What Does Lexis+ AI Cost vs Harvey AI in 2026?

What does Lexis+ AI cost vs Harvey AI in 2026?

As of October 2026, neither company publishes a price list. Third-party reports put Harvey at about $1,200 per seat per month on 12-month contracts with minimums of 20 to 25 seats. Lexis+ with Protégé, the product that replaced Lexis+ AI, is quoted firm by firm. Third-party estimates run from $128 to $494 per user per month, depending on how much content you buy.

Here is the short verdict for each buyer:

• Harvey: fits large firms and in-house teams that want a broad AI workbench and can sign a multi-seat annual contract.
• Lexis+ with Protégé: fits firms whose AI work is mostly research and citation-checked drafting built on LexisNexis case law, especially firms that already pay for Lexis+.
• OpenLaw for Attorneys (Lexi): fits small and mid-size firms that want AI to run firm operations like intake, client updates, drafting and billing, rather than buying another research seat.

One disclosure: we build one of these tools. Lexi, the AI paralegal in OpenLaw for Attorneys, is included because people searching this question also ask how Lexi compares to Harvey. It gets one entry and one honest take, same as the rest. This Lexi is not the same as getlexi.io, a different company that also uses the name Lexi.

How much does Harvey AI cost in 2026?

Harvey does not publish prices. You get a number only by booking a demo with its sales team. Third-party reports in 2026 cluster around $1,200 per lawyer per month on an annual contract with a 20 to 25 seat minimum. Some reports list higher per-seat prices for smaller firms and steep volume discounts for the largest firms.

The seat minimum matters more than the seat price:

• 20 seats at $1,200: $288,000 a year
• 25 seats at $1,200: $360,000 a year
• No free tier or self-serve checkout: as of October 2026, Harvey's site still sends every buyer to a demo request

Harvey's CEO has said the company now supports smaller firms, nonprofits and government agencies. We found no published small-firm price as of October 2026. Some reports describe a bundled tier with LexisNexis content at a higher seat price, but we could not confirm it with Harvey or LexisNexis, so ask for it in writing.

How much does Lexis+ AI cost in 2026?

Lexis+ AI is now sold as Lexis+ with Protégé. LexisNexis made it generally available in the United States in February 2026 as a full replacement for Lexis+ AI. The company does not publish a subscription price. Pricing depends on firm size, the AI features you pick and the content package.

Two kinds of pricing are visible:

• Subscription estimates: third-party analyses place the Lexis+ with Protégé bundle at $128 to $494 per user per month as of 2026, depending on scope.
• Per-use list prices: if your plan doesn't include flat-rate AI, LexisNexis's posted law firm price schedules list a Generative AI Ask at $99 per use. Third-party summaries also list Summarize and Drafting at $250 per use. These are list prices, and most firms negotiate them.

If your firm already pays for Lexis+, Protégé is usually priced as an upgrade to that contract. Ask your LexisNexis rep for the per-user add-on price and the per-use rates you would pay without it.

What do you get for the money?

Harvey sells breadth, and Lexis+ with Protégé sells depth in research. Harvey's platform includes agents that carry out multi-step legal work, Vault for storing documents and analyzing them in bulk, Knowledge for legal, regulatory and tax research, and contract review tools. Harvey reports more than 3,500 legal organizations as customers.

Lexis+ with Protégé launched with more than 300 pre-built workflows. They cover motions, discovery documents, contract redlines and clause analysis. It also has a no-code workflow builder and checks citations against Shepard's Citations. It uses models from Anthropic, Google and OpenAI, all behind one prompt box tied to the LexisNexis content library.

Lexi does a different job. It handles back-office and casework tasks: scheduling intake, drafting engagement letters and discovery responses, sending client updates and taking payments. It connects to tools such as Clio Manage and Google Calendar. If the expense you're trying to cut is staff time rather than research time, see what Lexi replaces in the firm operations stack.

Is Harvey or Lexis+ AI safe for confidential legal work?

Both vendors say they do not train models on your uploads, and both are SOC 2 audited. Harvey says it does not use inputs, outputs or uploaded documents to train models, and it requires zero data retention from its model providers. It reports SOC 2 Type II, ISO 27001 and ISO 42001. LexisNexis says its AI providers are contractually barred from training on customer data. It purges prompts after 90 days at most and has an annual SOC 2 Type 2 examination.

Privilege depends on more than the vendor's contract. In United States v. Heppner (S.D.N.Y., opinion dated February 17, 2026), Judge Jed S. Rakoff held that documents a defendant made on his own with a consumer AI tool were protected by neither attorney-client privilege nor work product. The court left open how enterprise tools used at counsel's direction would be treated. Contract terms alone don't settle that question.

ABA Formal Opinion 512 (July 29, 2024) still sets the baseline. Lawyers must understand the tool, protect client confidences, get informed consent where the risk calls for it, and bill fairly for time saved. Before you sign, get the vendor's current terms and SOC 2 report. Our guide on what law firms should demand on SOC 2 lists the questions to ask.

Where does Harvey still win, and where does Lexis+ still win?

Each product has a clear edge, and the right one depends on your work.

Where Harvey still wins

Harvey is the broader platform for large teams. It handles bulk document review in Vault, agentic workflows across practice groups, and adoption analytics for firm leadership. Since the June 18, 2025 LexisNexis alliance, Harvey users can also ask Protégé research questions inside Harvey. Answers come from LexisNexis U.S. case law and statutes, checked with Shepard's.

Where Lexis+ with Protégé still wins

Lexis+ with Protégé wins when the job is research you will cite to a court. Answers come from LexisNexis primary law with Shepard's verification. Firms already on Lexis+ add it to a contract they already have, and the per-use option lets a light user avoid a large seat commitment.

Where Lexi fits

Lexi fits when the bottleneck is running the firm rather than researching the law: intake, follow-ups, documents and invoices. It doesn't replace a case law database. Most firms pair it with whatever research tool they already use. The intake-to-invoice automation guide shows that workflow end to end.

Can firms use both Harvey and Lexis+ AI?

Yes, and the two companies are built to work together. Under the alliance announced June 18, 2025, LexisNexis content and Protégé answers are available inside Harvey. Motion to dismiss and summary judgment workflows were announced as the first joint workflows.

Paying for both makes sense when you have both kinds of users. Lawyers who need cited research use Lexis. Teams doing bulk review, contracts or firm-wide workflows use Harvey. It is hard to justify for a small firm, because Harvey's reported seat minimum alone costs more than many firms' entire software budget. Before paying twice, ask both vendors whether the Lexis content inside Harvey needs a separate LexisNexis subscription. The alliance announcement doesn't say.

Should you choose Harvey, Lexis+ AI or Lexi?

Pick the product that matches the work you want to take off your lawyers' plates.

• Choose Harvey if: you have 20 or more lawyers who will use it every day, a budget around $300,000 a year or more, and work that is heavy on document review, contracts or custom workflows.
• Choose Lexis+ with Protégé if: your AI use centers on research and drafting you will cite, your firm already has a LexisNexis contract, or you want pay-per-use instead of a seat minimum.
• Choose OpenLaw for Attorneys (Lexi) if: you are a small or mid-size firm whose time goes to intake, client communication, documents and billing, and you want one AI paralegal connected to your practice management system.

The verdict: Harvey for large firms buying a broad AI workbench, Lexis+ with Protégé for research-first firms, and Lexi for firms that want to automate operations. To weigh the spend against the hours you get back, see the ROI of AI for law firms.
