Evidentiary Workflow

From Raw Production to Courtroom Exhibits

A disciplined, end-to-end legal review process executed entirely inside the volatile memory of your local Mac.

STAGE 01

High-Speed Ingestion & Bates Indexing

Drop raw discovery folders. Lexnight parses multi-format PDFs, extracts Bates identifiers, and computes cryptographic SHA-256 hashes for instant evidentiary indexing at wire speed.

STAGE 02

Chronological Fact Synthesis

Local foundation models extract dated assertions, agreements, and notices into an interactive timeline. Every event is pinned directly to its source exhibit and exact page coordinates.

STAGE 03

Contradiction & Perjury Spotting

Cross-examines sworn deposition testimony against documentary exhibits (e.g., USPS postmarks, ERP server logs) to surface irreconcilable conflicts for impeachment in court.

Ethics & Legal Compliance

Why Air-Gapped Architecture Matters

How Lexnight satisfies Model Rule 1.6 and ABA Formal Opinion 512 without requiring client consent waivers.

The Cloud AI Disclosure Trap

Under ABA Formal Opinion 512, uploading confidential client discovery files to third-party cloud LLMs triggers affirmative obligations to evaluate vendor security and frequently requires informed client consent.

  • Cloud vendors ingest and cache client work product.
  • Potential waiver of attorney-client privilege.
  • Subject to third-party subpoenas and breach exposure.

The Lexnight Air-Gapped Standard

Lexnight is compiled with zero network entitlements in Apple's App Sandbox. Because no data ever crosses a network interface, client confidentiality remains completely intact on-device.

  • 100% on-device processing via Apple Silicon Neural Engine.
  • Zero network calls verified by macOS kernel sandboxing.
  • Full compliance with Model Rules 1.1, 1.6, and 5.3.

Technical Architecture

Built Exclusively for Apple Silicon

Engineered to leverage Unified Memory and the 16-core Apple Neural Engine for zero-latency offline intelligence.

HARDWARE ACCELERATION

Apple Silicon M1 – M4

Optimized for Apple's unified memory architecture. Review 50+ discovery PDFs simultaneously without memory thrashing or CPU thermal throttling.

SECURITY ISOLATION

Zero Network Entitlements

The macOS App Sandbox completely denies network access at the kernel layer. No telemetry, no usage analytics, no external API connections.

COURTROOM AUTHENTICATION

FRE 902 Self-Authentication

Every document record, timeline citation, and extracted finding is paired with a SHA-256 hash and millisecond audit log for admissible trial exhibits.

Common Questions

Frequently Asked Questions

No. Absolutely zero data leaves your Mac. Lexnight is compiled without network entitlements in Apple's App Sandbox. Even if you tried, the app cannot make outbound HTTP or socket connections. All PDF extraction, entity mapping, and contradiction spotting execute locally on your Mac's Apple Silicon chip.
Yes. Lexnight does not require Wi-Fi, cellular data, or an internet connection of any kind. You can review complex discovery dumps and prepare cross-examinations in courtrooms where cellular service is jammed or restricted.
Any Apple Silicon Mac (M1, M2, M3, M4 or Pro/Max/Ultra variants) running macOS 14.0 (Sonoma) or later. Intel-based Macs are not supported due to the absence of the Apple Neural Engine and unified memory architecture.
Searchable legal PDFs, Bates-stamped discovery productions, deposition transcripts, executed agreements, demand letters, and plain text files. Local OCR via macOS VisionKit is also integrated for scanned exhibits.
ABA Formal Opinion 512 addresses the ethical pitfalls of transmitting confidential client data to third-party generative AI cloud vendors. Because Lexnight operates 100% on-device without third-party data transmission, client confidentiality is preserved under Model Rule 1.6 without the need for disclosure or waiver.
