Local AI · Citation-Gated · Zero Hallucination

Legal AI That Doesn't Make Things Up

v1.0 · Mac + Linux + Windows · Local Ollama · No cloud dependency · PHI never leaves your machine

100% Local AI — No cloud AI ever
Zero hallucination by architecture
PHI never leaves your machine
Citation-gated — every answer traceable

Other AI tells you what it knows.
JurisCore tells you what it can prove.

Your current AI has read millions of documents. It generates confident answers that sound right — and sometimes aren't. For general tasks, that's fine. For legal work, it's a liability.

What general AI delivers

  • Confident answers — even when it's inventing case law
  • General knowledge stretched across every jurisdiction
  • No accountability when it gets it wrong
  • "I'm not sure" buried in a wall of plausible-sounding text

What JurisCore delivers

  • Every answer grounded in your jurisdiction's actual law
  • Citation gate — if it can't verify, it says "I don't know"
  • PreFlight flags risks a general AI wouldn't catch
  • Local model + local knowledge graph = last-mile accuracy

"I don't know" isn't a failure. In legal AI, it's the only honest answer.

Three Modules. One Local Stack.

PreFlight, MatterOS, and AI Research — integrated from day one, all running on your hardware.

New

PreFlight Intake Analysis

Screen a potential case in seconds. PreFlight finds what Google misses and what your current AI invents — red flags, missed imaging, cauda equina symptoms, case worth, demand letter. All grounded in your jurisdiction's law with citations on top.

MatterOS Case Management

Matter tracking, SOL countdowns, stage history, attorney notes, and client timeline — built for PI workflow. Clean split-panel interface, local storage, no cloud dependency.

Citation-Gated

AI Research — Zero Hallucination

Ask questions about per-jurisdiction statutes, case law, and procedure. Every answer verified against the local knowledge graph. The AI says "I don't know" rather than make something up. That's not a limitation — it's the architecture.

Document Generation

Engagement letters and demand letters — generated from templates with live matter data. PDF output, ready to review and send. One click from case data to client-ready document.

SOL Deadline Tracking

Automatic statute of limitations countdown for your jurisdiction. Visual alerts at 180, 90, and 30 days. Never miss a filing deadline — and never wonder if the AI's date estimate is real.

Local-Only Architecture

Everything runs on your machine. Ollama + local model + local knowledge graph = no data ever leaves your infrastructure. PHI never reaches a cloud. Not a preference. The product.
