Why Litigators
Choose Lex Arca Legal Vault™
Legacy document platforms and generic AI tools were not architected for the compliance demands of active litigation. Lex Arca™ was.
"Case law apps give you the library. eDiscovery apps give you the storage.
Lex Arca™ gives you the combat edge."

Common Questions
Everything you need to know about the Lex Arca Legal Vault™ platform and security architecture.
Yes. Unlike standard cloud tools, Lex Arca™ operates on a local-first architecture. Your evidence and trial outlines are processed inside your own private vault environment. Lex Arca™'s core system is architecturally excluded from indexing your files — aligned with ABA Formal Opinion 512 compliance obligations.
Neural Billing recognizes when you are actively drafting case premises, generating cross outlines, or evaluating transcripts. It registers these strategic micro-tasks in the background and writes them to an append-only, tamper-evident audit trail — prompting you to approve billable entries so no 0.2 or 0.5 hour block is forgotten.
Setting up a new matter takes less than 10 minutes. Once your secure local vault is established, you can import depositions, key exhibits, and pleadings. The Neural Librarian immediately indexes them semantically and is ready to assist with outlines, timelines, and contradiction queries.
Yes. Every firm receives a dedicated onboarding walkthrough covering vault configuration, Neural Billing setup, and pre-loaded mock trial files — so you can run HUD queries against realistic case data before going live in court.
