Private AI for
Law Firms

A complete legal AI workbench powered by on-device models. No cloud. No third-party processors. The app is physically incapable of sending your data out — and it can prove it to you live.

What's inside

A full legal workbench,
zero cloud dependency

Everything a litigation or transactional practice needs, running locally on a Mac Mini, Mac Studio, or any modern laptop.

🔒

PII Shield

Names, NRICs, phone numbers, emails, addresses, and bank accounts are masked before the AI sees any text, then restored in the result. Paste anything into the built-in preview and see exactly what the AI would receive.

🚫

Egress Lock

The app blocks its own network access at the socket level — it cannot reach anything beyond your machine even if it tried. Turn off Wi-Fi and everything keeps working.

💬

Legal Chat

Conversational AI for legal research, statutory interpretation, and procedural questions — every message passes through the PII Shield first.

📄

Contract Review

Upload a contract and receive a structured risk report identifying unusual clauses, missing protections, and key obligations.

📑

Redlining & Word Export

Compare versions or get AI-suggested edits — then export a real Word document with genuine tracked changes, ready for Accept/Reject.

📚

Court Bundles

Auto-sort authorities, generate relevance statements, and download a filing-ready PDF — cover page, table of contents, bookmarks per tab, continuous page numbers.

📅

Chronology

Extract and sort event timelines from multiple litigation documents into an editable chronology.

✍️

Drafting + 1,200-prompt library

First drafts of letters, billing narratives, and pleadings — plus a curated library of over 1,200 legal prompts across nine practice volumes.

🔍

Case Search

Semantic search over your uploaded case library. The index itself stores only masked text — even the search database never holds raw client identities.

📊

Resource Dashboard

Live CPU, memory, and GPU meters show exactly how hard the machine is working — so you always know what the AI is costing you: electricity, nothing more.

📋

Audit Log

Every action is recorded locally with timestamps and PII-masking counts (never the values). Exportable for compliance reviews.

💾

Any document, your choice

PDF, Word, PowerPoint, Excel — with a choice of fast or layout-accurate extraction engines, and optional OCR for scanned files.

Don't take our word for it.
Watch it prove itself.

OTG Legal Box runs the entire AI stack on your own hardware and enforces it in code: a socket-level egress lock makes outbound connections impossible, the PII Shield shows you live exactly what the AI sees, and an automated test suite fails the build if a single planted identity ever reaches an AI prompt. In a demo, we switch the Wi-Fi off first — then run everything.

Deployment

Install it like any app

The AI runtime is built into the installer. One download, one drag, one first-launch wizard — and an uninstall that leaves zero residue when you want it gone.

Install

Drag the app into Applications (Mac) or run the installer (Windows). The AI engine ships inside — nothing else to install.

First launch

A short wizard checks your hardware, recommends the right model size, and downloads it once. After that the internet is never needed again.

Work

Desktop mode on your own machine, or a Mac Mini serving the whole firm over office Wi-Fi. No accounts, no subscriptions.
