THE PLATFORM
Four products.
One sovereign stack.
Built as a single intelligence layer, not stitched from point tools. Every product shares the same corpus, the same reasoning stack, and the same deployment guarantees.
CORPUSATLAS
The legal record, entire.
2–10 PB across 63 jurisdictions — federal, state, regulatory, legislative, published and unpublished. Continuously ingested. Citation-normalized. Cryptographically sourced.
MEMORYMINIME
Your firm, agentified.
A local agentic system trained on your templates, your precedent, your work product. Institutional knowledge compounded — and kept on your infrastructure.
REASONINGNEUROMENTIS
Partner-grade drafting.
Specialized agents for litigation, transactional, and regulatory work. Citation validation, structured analysis, automated shepardizing — elite-lawyer reasoning, embedded.
ARCHITECTURE
SECURE AT EVERY LAYER
NO CLOUD REQUIRED
Built for how law
actually works.
Sophie — wisdom. Lex — law and protector of mankind. SophieLex is the intelligence layer for legal work where privilege, provenance, and professional responsibility are not optional.
01 / REASONING
Real legal reasoning.
Grounded analysis, structured argumentation, and collaboration between specialized agents — not next-token guessing dressed up as law.
02 / ZERO TRUST
Privacy is a property.
Client-matter segregation, explicit data routing, and least-privilege access enforced at the infrastructure layer. Nothing crosses the perimeter.
03 / RETRIEVAL
No hallucinated cases.
Authority-aware, citation-graph-aware retrieval with passage-level precision. Every result carries verifiable lineage back to source.
04 / DEPLOYMENT
Run it your way.
On-prem. Air-gapped. BYOC. The entire platform operates without cloud dependencies or frontier LLM calls. Sovereignty isn't a feature — it's the starting condition.
THE DATA
Atlas.
The most complete
legal corpus on earth.
Proprietary. Continuously ingested. Citation-normalized. Coverage that Westlaw and LexisNexis do not have.

RETRIEVAL
Authority-aware. Citation-aware.
Grounded to source.
LEGAL INTELLIGENCE RETRIEVALRanks by jurisdiction, court hierarchy, precedential weight, recency, and posture.
CITATION GRAPH NAVIGATIONTraverses citing, cited-by, and treatment relationships across authorities.
MATTER-SCOPED RETRIEVALAdapts to the facts, claims, venue, judge, and document set of each matter.
PASSAGE-LEVEL PRECISIONFinds the exact holding, quote, or procedural detail that supports the analysis.
CRYPTOGRAPHIC PROVENANCEPreserves source lineage, citation traceability, and version control — verifiable end-to-end.
SECURITY & DEPLOYMENT
Engineered for
privileged work.
Sovereignty is not an enterprise upsell. It is the foundation. Every layer — data, retrieval, reasoning, output — is designed for environments where data egress is not an option.
DEPLOYMENTSOVEREIGN
Runs inside your perimeter.
On-prem. Air-gapped. BYOC. The platform operates without cloud dependencies, shared infrastructure, or frontier LLM calls. Data never leaves your environment.
ARCHITECTUREZERO TRUST
Privacy is the architecture.
Explicit data routing, client-matter isolation, and least-privilege access enforced at every layer. Not a policy document — a property of the system.
INTEGRITYPROVENANCE
Cryptographically verifiable.
Every citation carries verifiable lineage. Every retrieval is traceable to source. Every output is auditable, append-only, and tamper-evident.
RESPONSIBILITYHUMAN-IN-LOOP
Attorney approval, engineered in.
Approval controls at every consequential action. The agent proposes; the attorney decides. Professional responsibility is not a risk — it is a build constraint.
