Structure Your
Legal Reasoning.
Win the Argument.
The first platform built on Wigmore’s chart method — turning scattered case notes into unbreakable, element-by-element proof chains for bar exam preparation, litigation strategy, and legal education.
Prevent circular logic. Expose missing elements. Map counter-inferences. Built on 100 + years of evidence scholarship.
Wigmorean proof chain — nodes, inferential arrows, and counter-evidence
Linear outlines cannot show missing elements, circular support, or weak inferential links. Those gaps surface at trial — too late to fix.
When “A proves B proves A,” no flat document catches it. A DAG makes circular logic structurally impossible — the graph simply cannot close.
Every element node must have supporting links. Nothing is assumed. Every gap is visible before you write a brief or walk into a hearing.
Built on a century of evidence scholarship
John Henry Wigmore developed the chart method in 1913 as a rigorous system for mapping every inference leading to an ultimate probandum. Anderson, Schum & Twining formalised it into modern proof theory. This platform is the first interactive implementation of that tradition.
Why DAGs? →Built for every stage of the legal career
From first-year bar prep to appellate brief — one method, one platform, every context where structured reasoning wins.
MEE, MPT, and Evidence — element-by-element DAG templates for every tested claim. No element is missing on exam day.
MEE · MPT · Evidence → Litigation StrategyCase theory mapping, deposition planning, and motion structuring — built around an unassailable proof chain.
Litigation · Motions → Evidence PlanningFoundation checklists, burden tracking, and admissibility stress-testing built into every evidence node.
Foundation · Hearsay → Law School & CLEPre-built subject templates for every MBE topic. CLE-integrated certification programs in development.
Templates · CLE →After validating in the legal market, the platform expands into clinical nursing reasoning, medical differential diagnosis, business risk mapping, and structured educational argument — same method, field-specific templates, enterprise licensing.
