LLexis+ with Protégé

LexisNexis says Lexis+ with Protégé sits on more than 200 billion documents, with over 4 million new ones added every day, and since August 2026 an orchestration layer decides which models, agents and sources to use for each task. It shows the plan first, lets the lawyer edit it, then checks its own work and Shepard’s citations before handing back a draft.

It is best for firms and legal departments already paying for Lexis+ that want agentic research, drafting and repeatable workflows without adding another vendor. Points to plan for are pricing and the platform requirement: prices are shared by quote with no trial, a third-party tracker reports a median contract of $14,400 a year, and a Lexis+ subscription is required. We rate it 8.1/10 on our scale. We have not used Protégé ourselves; this review is based on LexisNexis announcements, LawSites reporting, third-party pricing data and public reviews.

Content Scale and a CTO’s Take on Model Strategy

LexisNexis’s numbers describe scale of content more than adoption, and the most revealing detail came from its chief technology officer on model strategy.

For a buyer, the content figures are the real argument. Protégé’s agents can search, draft and check citations against the same library and citator many firms already use, which narrows the gap between a fluent AI answer and a defensible one. The model history is a useful signal too: LexisNexis tried to build its own tuned models, found the gains did not justify the cost, and now routes work to the best general model for each task while testing its own again.

The public review record is still small. Three G2 reviews of the predecessor product give an early read on user satisfaction, so a pilot on real matters is the best test.

One Prompt Box and Prebuilt Workflows Inside Lexis+

Lexis+ with Protégé is a single workspace inside Lexis+. Lawyers type a request in one prompt box or start a prebuilt workflow.

The Agentic Loop

• Interpret: the orchestration layer reads the request and selects the models, agents, skills and content sources that fit it.
• Plan: it presents a plan before it runs. The lawyer can change it, for example by switching jurisdiction or adding or removing data sources.
• Execute: it searches Lexis content and the web together, validates web citations and drafts output. It can bring in more tools or information mid-task.
• Check: it reviews its own work and loops back to redo parts that do not answer the request. Shepard’s Verify checks whether cited cases are still good law and relevant to the task.
• Deliver: it shows the source behind each part of a draft and exports to Word, Excel or PowerPoint.

Before August 2026, Protégé followed scripted workflows. The new design adapts its steps to the task, and it keeps context within a session; LexisNexis says later versions will remember past documents and user preferences.

Workflows and Skills

The prebuilt library spans litigation (motions, discovery, case strategy and fact extraction), transactional work (contract drafting, redlining and risk review) and everyday tasks such as client alerts, timelines, interview summaries and audio transcription. Practice-area workflows for civil litigation, M&A, real estate and labor and employment were announced as coming soon, along with a judicial workflow for bench memos and opinions. The no-code Custom Workflow Builder lets firms choose the model, test a workflow before publishing and share it across teams. Several hundred skills package instructions for document types and client communications, and firms can customize the defaults.

Connected Content

Without switching products, the system draws on Lex Machina for judge and court analytics, Intelligize for SEC research and Law360 for news. Firms can also connect their own document management system and upload their own documents.

Quote, Subscription and White Glove Onboarding

• Subscription: confirm Lexis+ coverage and add Protégé through a LexisNexis sales quote.
• Onboarding: LexisNexis offers a white glove service with workflow teams that help build, migrate and standardize workflows and train users.
• Connect: link the firm’s document management system and decide which internal documents Protégé can use.
• Customize: adapt default skills and build firm workflows in the no-code builder.

Regulators Still Hold the Lawyer Responsible

LexisNexis’s general counsel has pointed out that regulators hold lawyers responsible for what they file. Lawyers approve the plan, read the sources the system cites and sign off on every draft.

Quote-Only Pricing and a Reported Median Contract

LexisNexis does not publish Protégé prices. Buyers request a quote, usually as part of a Lexis+ subscription.

The median figure comes from a small sample of four buyer reports, so treat it as a rough guide rather than a list price. There is no free plan or self-serve trial.

What the $14,400 Median Means for a Small Firm

These illustrations use the reported median. Seat counts are our own assumptions, and real quotes will differ.

• A small firm paying the median: $14,400 a year is $1,200 a month. If that contract covered five lawyers, the cost would be $240 per lawyer a month, before the underlying Lexis+ subscription.
• A firm comparing with CoCounsel Legal: CoCounsel Legal is reported at $784 per attorney a month on a 1-year term for small firms. Ask LexisNexis for a per-lawyer figure on the same term length so the two quotes compare like for like.
• A larger firm: expect a negotiated enterprise agreement where Protégé is priced together with Lexis+, Lex Machina or Law360 subscriptions.

Other costs to plan for: the Lexis+ base subscription, any add-on products the orchestration layer draws on, and staff time to build and maintain custom workflows. Confirm whether workflow-building services are included or billed separately.

Lexis+ with Protégé Compared With CoCounsel Legal, Harvey, Legora and Clio Work

Protégé’s direct rival is Thomson Reuters’ CoCounsel Legal. Harvey and Legora are independent AI workspaces, and Clio Work serves smaller firms.

For most firms the choice between Protégé and CoCounsel Legal follows the research subscription they already hold, since each is strongest on its own content and citator. Protégé’s orchestration layer and built-in Lex Machina and Intelligize data suit litigators and securities teams; CoCounsel’s published small-firm prices make budgeting easier. Against Harvey and Legora, Protégé’s case is that every research answer sits on a citator, while their case is broader document work across a firm’s own files without tying the firm to one publisher. Firms that do a lot of bulk contract review alongside research sometimes run one of each. See our guides to AI agents for law firms and legal AI agents.

Litigators and Firms Already Paying for Lexis+

• Lexis+ subscribers: Protégé adds agentic research and drafting on content and citations the firm already pays for.
• Litigators: Shepard’s Verify inside drafting, Lex Machina analytics and workflows for motions and discovery cover much of a litigation team’s work.
• Securities and regulatory teams: Intelligize SEC research and Law360 news feed into the same workspace.
• Firms that want to standardize processes: the no-code builder and customizable skills turn house methods into shared workflows.
• Teams that want model choice: the system picks among Anthropic, Google and OpenAI models, or lets users choose.

Westlaw Shops and Firms Wanting Vendor Neutrality

• Westlaw firms: CoCounsel Legal offers comparable agentic research on Westlaw content.
• Buyers who need a list price: Protégé is sold by quote, and a trial is not offered.
• Firms wanting a vendor-neutral workspace: Harvey or Legora work across documents without tying the firm to one research database.
• Plaintiff personal injury firms: specialist tools such as Supio, Eve and EvenUp focus on medical records, demands and intake.
• Teams outside the US that need every feature now: global rollout was scheduled through 2026, and some broader workflows are tied to US primary law.

The Lexis+ Base Subscription and a Fast Pace of Updates

• Base subscription: a Lexis+ subscription is reported as required, so the true cost is Protégé plus Lexis+.
• Frequent updates: the product moved from Lexis+ AI to Lexis+ with Protégé in February 2026 and to a new orchestration engine in August 2026; training materials and workflows may need updating.
• Features announced as coming soon: practice-area workflows, firm-built skills and long-term memory were announced without firm dates.
• Early public reviews: 3 G2 reviews exist for the predecessor product so far, so reference customers are a useful addition.
• Model changes: LexisNexis routes tasks among several outside models and plans to preview its own; ask how model changes are communicated and whether firms can pin a model for consistency in a matter.
• Workflow upkeep: custom workflows and edited skills are firm assets that need an owner, especially when the underlying engine changes.
• Lawyer responsibility: citation checks reduce risk but do not remove the duty to verify every filing.

The Legal Intelligence Engine Rebuild of August 2026

• On August 24, 2026, LawSites reported that LexisNexis rebuilt Protégé around an agentic orchestration layer it calls the Legal Intelligence Engine, with editable plans, self-checking and Shepard’s Verify in drafting.
• On February 24, 2026, LexisNexis made Lexis+ with Protégé generally available in the US, replacing Lexis+ AI as its flagship.
• On January 21, 2026, LexisNexis launched a commercial preview of Protégé AI workflows with hundreds of prebuilt workflows and a no-code builder.

The Natural First Agent for Existing Lexis+ Firms

For firms already on Lexis+, Protégé is the natural first agent to test, because it does agentic work on content and citations the firm already trusts and adds Lex Machina, Intelligize and Law360 data in the same place. The August 2026 redesign moved it from scripted workflows to a system that plans, checks itself and shows its sources, which is what cautious firms want from legal AI.

It scores 8.1/10 on our scale. Autonomy and integrations are strong; pricing value scores lower because prices come by quote, there is no trial and a base subscription is required, and user sentiment rests on three reviews so far. Published pricing and a trial would help buyers. Ask for a pilot, a per-lawyer price on a fixed term and reference customers, then compare against a CoCounsel Legal quote.

Models, Cost and the Lexis+ AI Name Change

How Much Does Lexis+ with Protégé Cost?

LexisNexis does not publish prices. A third-party tracker reports a median contract of $14,400 a year based on four buyer reports, and says a Lexis+ subscription is required. Ask for a quote that separates Protégé from the base subscription.

Is Protégé the Same as Lexis+ AI?

Lexis+ with Protégé replaced Lexis+ AI as LexisNexis’s flagship legal platform when it became generally available in the US on February 24, 2026. It keeps the conversational research and drafting and adds workflows, a workflow builder and, since August 2026, agentic orchestration.

Which AI Models Does Protégé Use?

LexisNexis uses enhanced general models from Anthropic, Google and OpenAI and picks the best one for each task unless the user chooses. It plans to preview its own models later in 2026.

How Does Protégé Compare With CoCounsel Legal?

Both run agentic research grounded in their publisher’s content and citator: Lexis and Shepard’s for Protégé, Westlaw and KeyCite for CoCounsel. CoCounsel publishes small-firm prices through a configurator, while Protégé is quote-only.

Does Protégé Check Its Own Citations?

Yes. Shepard’s Verify checks citations during drafting and whether a case is relevant to the task, and web-sourced citations are validated. Lawyers still remain responsible for verifying what they file.
