Does Lexi Do Everything Harvey Does?

Does Lexi do everything Harvey does?

No. Lexi does not do everything Harvey does, and it isn't built to. Harvey fits large firms building out AI for substantive legal work: research, drafting, contract analysis and review of big document sets. Lexi, the AI paralegal in OpenLaw for Attorneys, fits small and mid-sized firms that want the operational work around legal practice handled. That means intake, scheduling, client follow-up, document collection, engagement letters and payment posting.

One disclosure: we build one of these tools. It gets one entry and one honest take, same as the rest. Where we couldn't verify something about either product from a public source, we say so.

Who this is for: firm owners, partners and administrators deciding where AI belongs in their firm.

Prices checked: October 2026. Harvey doesn't publish prices, so the Harvey figures below come from third-party reports.

Same name, different company: the "Lexi" at getlexi.io is a separate company that sells its own legal AI platform. Some search answers about "Lexi vs Harvey" are about that product, not this one. This page is about Lexi in OpenLaw for Attorneys at lexi.law.

What does Harvey do that Lexi doesn't?

Harvey does the legal thinking work: research, drafting and document analysis. Lexi doesn't try to do any of it.

Harvey's security page lists these products as of October 2026:

• Agents: purpose-built agents for complex legal tasks.
• Vault: secure document storage and bulk analysis of large document sets.
• Knowledge: legal research across domains.
• Spaces: shared, secure workspaces.
• Contract Intelligence: contract analysis and negotiation tools.
• Horizon Scanning: tracking regulatory change.

On June 18, 2025, LexisNexis and Harvey announced a strategic alliance. It brings LexisNexis Protégé, U.S. case law and statutes, and Shepard's Citations into Harvey. The two companies also announced shared motion-to-dismiss and summary-judgment drafting workflows. Harvey also has a Microsoft Word add-in. Its release notes say LexisNexis content is not yet supported inside that add-in.

If you need any of this, Lexi is not a substitute. Our own page on what Lexi replaces says it plainly: Lexi doesn't replace legal research platforms or legal drafting tools.

What does Lexi do that Harvey doesn't?

Lexi handles the work between your systems: getting a client in the door, keeping them informed, and moving the matter along. Harvey's product list doesn't focus on that layer.

Lexi's published capabilities include:

• Intake: scheduling consultations, calling clients back and sending follow-up emails.
• Engagement: drafting engagement letters and collecting documents from clients.
• Matter work: preparing filings and discovery responses, and keeping dockets and case details current in the tools you already use.
• Client updates: drafting client communications that an attorney approves before they go out.
• Billing tasks: posting payments.

Lexi asks an attorney for input when a task needs judgment. It works alongside Clio Manage, Westlaw, Google Calendar, Slack and Microsoft Teams, so it doesn't replace your practice management system. For more on the front end of that workflow, see our guide to AI-powered client intake. The same pattern, run from intake to invoice, is covered in our Legora vs Lexi comparison.

How does Lexi vs Harvey pricing compare?

Neither company publishes prices, so you get a real number only from a sales conversation. Third-party reports put Harvey well above what most small firms spend on software.

Harvey doesn't publish pricing, offer a free tier or have self-serve checkout. Third-party reports from 2025 and 2026 put Harvey at roughly $1,000 to $2,000 per user per month for mid-sized firms. They also report minimums of about 25 seats on annual contracts. The writers say these figures are reported or estimated, not official. Lexi's pricing isn't published either. OpenLaw quotes it after a demo.

Treat any number as a starting point for negotiation. Ask both vendors about seat minimums, contract length and caps on renewal increases. To work out whether either tool pays for itself, use the framework in the ROI of AI for law firms.

Is my data safe with Lexi, and is Harvey safe for confidential work?

Both vendors publish enterprise security claims. Harvey's are more detailed in public. Either way, your duty under the ethics rules is to check the contract, not just the marketing page.

As of October 2026, Harvey's security page lists SOC 2 Type II, ISO 27001, ISO 27701 and ISO 42001. Harvey says its Platform Agreement contractually guarantees that it won't train underlying models on customer inputs, outputs or documents. Lexi's site lists SOC 2 Type II, encryption in transit and at rest, a full audit trail with source attribution, and a commitment that firm workflows and expertise stay private to your organization. Ask OpenLaw for the written terms on training and retention before you sign, as you would with any vendor. Our post on what to demand on SOC 2 lists the documents to request.

Why the contract terms matter for privilege

In United States v. Heppner, No. 25 Cr. 503 (S.D.N.Y. Feb. 17, 2026), Judge Jed S. Rakoff held that documents a defendant made on his own with a public AI tool were protected by neither attorney-client privilege nor the work product doctrine. The tool wasn't a lawyer. Its privacy terms gave him no reasonable expectation of confidentiality. And he wasn't acting at counsel's direction. Commentators read the opinion as leaving room for a different result with enterprise tools used at a lawyer's direction under contractual confidentiality and no-training terms.

ABA Formal Opinion 512 (July 29, 2024) points the same way. Lawyers must assess whether a tool may use client data for self-learning. They need informed client consent where that risk exists, and boilerplate in an engagement letter isn't enough. Time spent learning a tool generally can't be billed to clients.

Where does Harvey still win?

Harvey wins wherever the job is legal analysis at scale. Lexi doesn't compete there.

• Research grounded in case law: the LexisNexis alliance brings in primary law and Shepard's checking.
• Big document sets: Vault is built for bulk review in diligence, investigations and discovery.
• Drafting in Word: lawyers can query Harvey from inside the document.
• Certifications: Harvey's public certifications go beyond SOC 2.
• Large firm rollouts: seat-based enterprise contracts suit firms with hundreds of lawyers and a team to run the rollout.

Can firms use both Harvey and Lexi?

Yes. Because the two tools sit at different layers, they overlap very little. A firm can use Harvey for research and drafting and Lexi for intake, client communication and administrative follow-through.

The practical question is budget, not compatibility. Few small firms can justify Harvey's reported seat minimums. A firm that size usually gets more from fixing operations first and adding a research tool it already has access to, such as Westlaw or Lexis+ AI. A large firm with Harvey in place may still have the operations gaps that Lexi is built for. Our checklist on how to choose legal AI walks through mapping tools to the work they replace.

Should you choose Harvey or Lexi?

Pick the tool that matches the work that's slowing your firm down. That might be legal analysis or the operations around it.

Choose Harvey if:

• your bottleneck is research, drafting or document review;
• you have dozens of lawyers or more and can commit to an annual enterprise contract;
• you want LexisNexis content and Shepard's inside your AI tool.

Choose Lexi if:

• your bottleneck is intake, scheduling, client updates, document collection or billing follow-through;
• you run a small or mid-sized firm and already use Clio, Westlaw or similar tools;
• you want attorney approval on client-facing work without adding staff.

The verdict: Lexi doesn't do everything Harvey does, and Harvey doesn't do what Lexi does. Harvey is legal work AI for large firms. Lexi is an operations paralegal for firms that want fewer administrative hours.
