CaseFile Reasoner
A litigation and due-diligence workbench that takes a client memo and produces a structured 'map of the case' — every theory of the case ranked, the evidence each one requires, and the rival theories that survive scrutiny — so junior associates stop writing one-sided briefs.
Litigation associates and paralegals preparing case memos and motion drafts
- Theory-of-the-case graph showing each candidate argument, its required proof, and the strongest counter-theory
- Auto-flag of arguments that lack a falsifiable evidentiary standard (the harness refuses to ship them)
- Citation thread that ties every claim in the memo back to a specific document in the case file
- Side-by-side 'devil's advocate' panel showing how opposing counsel would attack each theory
The DeepReason approach was demonstrated end-to-end on a real open-ended explanatory question ('why does time have an arrow?') and surfaced 20 argued survivors — that same rigor mapped onto a case memo would catch the overconfident single-theory drafts lawyers produce every day.

Searches for 'case theory mapping AI' return zero purpose-built tools; leading platforms (Harvey, CoCounsel, Lexis+ AI, Westlaw Precision) focus on research and drafting, not structured theory ranking with rival-theory stress-testing — a clear unfilled niche, though incumbents could expand.Best AI Legal Tools in 2026: VerdictLegal vs Harvey vs CaseText vs Westlaw ↗AI Tools for Legal Research in 2026: Harvey, Westlaw AI, Lexis+ AI ↗

Litigation is a durable, regulation-bound workflow; statutory and case-law churn guarantees recurring need for memo drafting, and AI-augmented (not autonomous) legal work sidesteps most bar-association replacement risk.
Building a defensible 'map of the case' with theory ranking and required-evidence mapping requires deep legal-domain modeling beyond off-the-shelf prompting; outputs must be citation-grounded to be trusted, and bar-society hallucination concerns add QA burden.
