What's buried in your documents that you don't know about?
Every case has contradictions, patterns, and connections hiding across thousands of pages. Manual review catches some. Keyword search catches more. Lumen catches everything.

Which witnesses contradict themselves?

Deposition on March 3: "I never met her." Affidavit on June 12: "We spoke several times." Your team may never connect these. Opposing counsel will.

Lumen tracks every claim per witness across all documents, chronologically.

How are these parties connected?

The relationship between your client and a key witness goes through three intermediaries mentioned in different filings five years apart. No keyword search finds that.

Lumen's knowledge graph maps every relationship and finds the shortest path.

Who was where, and when?

Flight logs in Exhibit 4. A deposition mention on page 200. A hotel receipt in a discovery response. The pattern is there — but only if you can see it all at once.

Lumen extracts person-location-date triples and plots them on a map.

What exactly did they say under oath?

You remember the gist but need the exact words. They're somewhere in 500 pages of deposition transcript. Finding them takes hours.

Lumen extracts verbatim quotes with source attribution and evidence classification.

When did they first know?

Proving knowledge is half the battle. The timeline of who learned what from whom is scattered across emails, depositions, and filings over years.

Lumen builds a chronological knowledge flow: who → learned what → when → from whom.

What did you miss in the last case?

The average document review catches 60–80% of relevant facts. For a case with thousands of filings, that leaves hundreds of claims, connections, and contradictions unseen.

Lumen reads every page. Every claim. Every name. Every date. Nothing slips through.
The knowledge graph that connects everything
Other tools search documents. Lumen understands the relationships between them — who said what, to whom, when, and how that connects to every other fact in your case.

Relationship mapping

Every person, organization, and entity extracted and linked. See who's connected to whom, through what, and how many documents confirm it.

Knowledge flow

Who learned what, when, and from whom. A chronological trail of how information moved between people — across depositions, emails, and filings.

Path finding

How is your client connected to that witness? Lumen traces the shortest path through the graph — revealing intermediaries no one thought to look for.

Cross-document entity resolution

"J. Smith", "John Smith", "Mr. Smith, Esq." — Lumen knows they're the same person. Every alias, every mention, unified into a single profile.

Contradiction surfacing

When Witness A's sworn testimony conflicts with Witness B's declaration, Lumen flags it — with verbatim quotes, page numbers, and dates.
