Verdict at a glance

Recommended for

Firms with substantial federal litigation that want judge, counsel, timing and damages analytics.

Bottom line

Worth a demo for firms with meaningful federal litigation who use judge and counsel analytics to plan strategy or win business. Confirm your state venues are covered and whether you need Lex Machina or the separate Lexis+ analytics feature.

LexisNexis' litigation analytics platform, with data on judges, courts, parties, counsel and expert witnesses: outcomes, damages, resolutions, timing and judge-specific findings, now queryable through Protégé AI. Coverage includes all 94 federal district courts and 13 courts of appeal, PTAB and selected 'enhanced' state courts. Pricing isn't published.

Not for

Mostly state-court or transactional practices, and buyers who want published prices.

Quick answer

Bottom line: Lex Machina is for firms with regular federal litigation that use data on judges, opposing counsel, timing and damages to plan strategy or pitch clients. Pricing isn't published; LexisNexis offers a demo and a quote (checked October 15, 2026). We found no self-serve trial. The contract trap: term, renewal and any annual increase aren't public, and LexisNexis research deals are often multi-year, so get those terms in writing (confirm with LexisNexis).

Lex Machina is LexisNexis' litigation analytics platform. It turns court records into data on judges, courts, parties, counsel and expert witnesses: case outcomes, damages awarded, how cases resolve, time to key milestones, and judge-specific legal findings. LexisNexis says it now works with Protégé, its generative AI, so you can ask questions in plain language. LexisNexis says coverage includes all 94 federal district courts, 13 courts of appeal, PTAB, specialty venues and selected state courts. Check state coverage for your venue first.

  14. How we reviewed

We built this review from LexisNexis' Lex Machina product page and its published Small Law price schedule. Everything was checked October 15, 2026. Features are vendor claims and change, so confirm with LexisNexis.

Disclosure: Some listings on AI Tools For Law may be sponsored or include affiliate or referral links. Paid placements are always labeled "Sponsored," and payment never changes our verdicts. LexisNexis hasn't paid for this review. Nothing here is legal advice.

What does Lex Machina actually do?#

Per LexisNexis, Lex Machina combines its own technology with AI-assisted attorney review to turn raw court documents into structured data. You can analyze:

  • Judges: how they've ruled on motions, specific legal findings, and timing.
  • Courts: time to trial, summary judgment and other milestones.
  • Parties and counsel: litigation history, outcomes and who they've faced.
  • Expert witnesses and damages awarded.
  • State court motion metrics for more than 40 motion types by judge, in covered state courts.

LexisNexis says that, as of April 2025, its data spans 45 million documents across more than 10 million cases, 8,000+ judges and 6,000+ expert witnesses, plus 18 million additional state cases used for party analytics. These are vendor figures we couldn't independently confirm. It also publishes annual litigation reports by practice area.

What this means for you: Lex Machina helps answer strategy questions, such as how a judge tends to rule on a motion or how long a case type usually takes, with data rather than anecdote.

How much does Lex Machina cost?#

LexisNexis doesn't publish Lex Machina pricing, and there's no self-serve trial. The product page offers a demo request.

Two cost points to keep in mind:

  • Lex Machina isn't Lexis+ Litigation Analytics. Lexis+ has its own analytics feature. If you already subscribe to Lexis+, price that option alongside a standalone Lex Machina contract.
  • Out-of-plan charges on Lexis research can add up. The LexisNexis Small Law price schedule (effective October 2, 2026) lists list prices for material used outside a flat-rate subscription (vendor prices, checked October 15, 2026), including a $60 system access charge, $24 per primary-law document and $95 per Practical Guidance document. Lex Machina isn't listed there, but ask how any bundle you buy handles out-of-plan use.

How hard is Lex Machina to set up?#

Technically easy: it's a web app. Getting value from it takes time to learn the filters and how each metric is defined, so ask for training as part of the deal.

What do users say about Lex Machina?#

We found too little credible independent user feedback to summarize fairly. Ask LexisNexis for references at firms with a similar practice mix, and run your own venue and judge questions during the demo.

Buyer tips before you sign#

  1. Get the state court coverage list for every venue you litigate in.
  2. Compare Lex Machina with Lexis+ Litigation Analytics if you already use Lexis+.
  3. Ask whether Protégé features are included or cost extra, and whether usage is capped.
  4. Get the term, renewal, any annual price increase and seat definitions in writing.
  5. Bring real questions to the demo, such as your judge's summary judgment record.

Pros and cons#

Pros

  • Full federal coverage, including appeals and PTAB.
  • Judge, counsel, damages and timing analytics.
  • State motion metrics where covered.
  • Plain-language queries via Protégé.

Cons

  • No published pricing.
  • Selective state coverage.
  • Easy to confuse with Lexis+ analytics.
  • Learning curve.

How does Lex Machina compare?#

Lexis+ AI with Protégé is LexisNexis' research platform, with its own analytics feature. Westlaw offers research with its own litigation tools. CourtListener is a free, non-profit source of federal opinions and dockets, without Lex Machina's analytics layer.

Who should use Lex Machina?#

FAQ#

How much does Lex Machina cost?#

LexisNexis doesn't publish pricing (checked October 15, 2026). Request a demo and a quote, and ask whether Protégé features cost extra (confirm with LexisNexis).

Which courts does Lex Machina cover?#

All 94 federal district courts, the 13 federal courts of appeal, PTAB, specialty venues and selected state courts, per LexisNexis.

Is Lex Machina the same as Lexis+ Litigation Analytics?#

No. They're separate LexisNexis products.

Does Lex Machina use AI?#

LexisNexis says Lex Machina now works with Protégé, its generative AI, and that its data is built with AI-assisted attorney review.

Is any of this sponsored?#

No. If that changes, the listing will be labeled "Sponsored," and payment won't change the verdict.
