In practice

A research question is really five questions in a trench coat. LexisNexis's Protege breaks the complex query into tasks and works them, instead of forcing one flat search.

You need answers you can cite, not a model's best guess. Protege is grounded in LexisNexis primary law and Shepard's, so the research traces to authoritative sources.

Your firm worries about confidential matters going into a public model. LexisNexis runs Protege in a secure environment, applying legal-tuned and general models without exposing your work.

Pricing

From $175/seat/mo

seats

Trial available

Included quota

Lexis+ research base includes natural-language search, Shepard's citations, Practical Guidance, and Document Analysis; Protégé AI (conversational research, drafting, Workflows) is an additional paid layer, not included in base tiers.

What is public

LexisNexis runs two pricing worlds. For solo/1–3-attorney firms it publishes Lexis+ research tiers (roughly $114–$257/seat/mo list, annual). For larger firms, pricing is an opaque enterprise sales process. The AI layer — Lexis+ with Protégé (formerly Lexis+ AI, renamed Feb 2026) — is NOT bundled into any tier and is quoted separately via sales (888-AT-LEXIS).

Billing mechanics

Per-seat (named-user) subscription for small firms; usage-projection-based enterprise contracts (1–3 yr) for larger firms. The seat price stacks: base Lexis+ content + jurisdictional/practice-area libraries + add-on modules (analytics, public records) + the Protégé AI layer priced on top. Activity outside the flat subscription bills under a separate transactional list-price schedule.

Cost watchouts

Protégé AI sold separately on top of base, mandatory admin fees, content/jurisdiction add-ons forcing upgrades, out-of-plan transactional charges, ~15%/yr renewal uplift, named vs concurrent licensing

Variable cost rationale

Flat subscription is predictable, but out-of-plan transactional charges and content add-ons add moderate variable cost; the AI layer is a separate fixed add-on

Additional watchouts

Advertised base tiers are floor costs, not real budgets; the useful AI (Protégé) is a separate, contact-priced line item

Overage / add-ons

Activity outside the flat subscription bills per the LexisNexis transactional list-price schedule (System Access Charges, per-document/alert fees); content not in your plan triggers add-on charges.

Sales call required

Yes, required for paid access

Lowest paid plan

Enterprise (~$175-300/seat/mo + base; ~$17.5K/yr)

Commercial notes

Multi-year commitments unlock ~15–25% discounts; concurrent (vs named) licensing can save ~20–30%; median enterprise contract ~$17K/yr (Vendr, 82 deals); a 20-attorney firm typically ~$30K–$60K/yr; law-school academic access common

Key ambiguities

The Protégé/AI per-seat price isn't published and is quoted separately; base 'list' tiers understate real spend once add-ons and AI are included

Cancellation / refund

Enterprise contracts run 1–3 years (locks price; ~15%/yr increases common); refund terms deal-specific; order processing up to 72 hours; an account executive manages the contract

Support SLA / resale

Dedicated account executive and enterprise support on larger contracts; small-firm tiers get standard support

Missing data

Protégé/Lexis+ AI per-seat pricing is not published (quote-only via sales); exact tier feature splits and enterprise rates depend on negotiation, firm size, and content mix
