The Problem Litigation Lawyers Face Today
Filing Deadlines Leave No Room for Slow Research
Court-imposed filing deadlines are non-negotiable. When you have 48 hours to file a reply with supporting authority, spending 6 hours on manual research is not an option.
Opposing Counsel Cites Cases You Have Never Seen
You walk into court and opposing counsel drops a precedent from a different circuit court that directly contradicts your position. No systematic way to anticipate every relevant case across all jurisdictions.
Precedent Freshness Is Hard to Verify
You cite a 2019 appellate court judgment without realizing it was distinguished in 2022 and effectively overruled in 2024. Manually checking whether your authorities are still good law across the citation chain takes hours.
Evidence Timelines Are Built Manually
Building a chronology of events from 200 pages of pleadings, affidavits, and exhibits means manually reading every document and extracting dates. One missed event can undermine your timeline argument.
Citation Chains Break at 1 Hop
You find a relevant case, but you cannot see what it cites or what cites it beyond the immediate references. Missing a key case 2 or 3 hops away means missing the strongest authority in your chain.
Keyword Search Misses Conceptually Relevant Cases
A search for "specific performance" misses cases that discuss the same principle using "decree for performance of contract" or "enforcement of contractual obligation". Traditional databases match words, not legal concepts.

Questions from Litigation Lawyers
How does AI search find cases that keyword search misses?
AI search understands legal concepts, not just exact words. A search for "landlord eviction grounds" finds cases discussing "forfeiture of lease", "re-entry by lessor", and "termination of tenancy" - terminology variations that keyword search would miss entirely.
What does "3-hop citation graph" mean in practice?
For any case, you see its direct citations (1 hop), the cases those cite (2 hops), and one more level (3 hops). This reveals the full authority chain. For example, your case follows Case B, which follows Case C, which was the original SCOTUS ruling - and you would have missed Case C with a 1-hop view.
How quickly does the citation freshness signal update when a case is overruled?
Citation relationships are updated as new judgments are indexed, typically within 24-48 hours of publication. When a new judgment overrules or distinguishes an older case, the freshness signal on the older case updates automatically.
Can the chronology builder handle documents with inconsistent date formats?
Yes. The extraction engine handles multiple date formats commonly found in legal documents, court orders, and correspondence. It normalizes all extracted dates into a consistent timeline. You can manually correct any extraction errors before export.
How do I prepare for opposing counsel arguments I have not seen?
Search for the legal principle opposing counsel is likely to argue. The AI search surfaces cases from all jurisdictions, including circuit courts you may not have checked. Then map the citation network to see if any of those cases strengthen or weaken your position.
