NativeCluster / Legal Box Private AI for law firms

§01 · The promise

Attorneyclient privilege, preserved.

Legal Box runs large language models over your firm's own documents, on an appliance that sits in your office. No cloud, no API, no vendor with a copy of your files. As private as a locked filing cabinet.

On-premise. nothing transmitted offsite Air-gapped. private by architecture Owned. one appliance, your hardware
§02 · What it does

Drafting, review, and management of your own documents.

The three things a firm does with its documents, run by large language models that never leave the office.

01

Document drafting

First drafts of agreements, letters, and memos, generated from your firm's own templates and precedents, in your firm's voice.

02

Document review

Read, summarize, and flag across long documents: full case files and lengthy agreements.

03

Document management

Search, organize, and answer questions across your firm's entire corpus, with nothing indexed or stored offsite.

§03 · The problem

Cloud AI puts privileged files outside your control.

A partner is personally responsible for client confidentiality. Sending privileged material to a cloud AI service places that data on someone else's servers. That is why many firms restrict or ban these tools outright. The conflict is structural, not a setting you can toggle.

Inside your firm · Legal Box
  • Documents stay on the appliance
  • Every prompt processed on-premise
  • Nothing transmitted to a third party
Outside · cloud AI
  • Files leave your network
  • Held by an AI vendor you don't control
  • Your usage may train their models, even when they say it won't
  • Privilege and confidentiality at risk
§04 · How it works

A configured appliance you plug in, not a project to babysit.

Legal Box is a self-contained cluster of Apple Silicon hardware, pre-configured and supported. It arrives working.

Step 01

Plug it in

The appliance sits in your office or server closet and joins your network. No external accounts to create.

Step 02

Point it at your files

It ingests your firm's own documents (case files, contracts, precedents) entirely on-device.

Step 03

Work, air-gapped

Your team drafts, reviews, and asks questions. Nothing it processes ever leaves the building.

§05 · Capability

Capable models, kept entirely in your office.

A cloud data center will always have more raw horsepower. That isn't the trade Legal Box makes. It runs capable open-weight language models on hardware you own, so your privileged material never leaves the building. The advantage isn't doing more. It's doing it privately.

For the work a firm actually needs (drafting, review, and search across its own documents), that's the trade worth making: private and in your control, rather than powerful and exposed. Which models fit your work, we confirm with you on the call.

§06 · Security & data sovereignty

The architecture, described plainly.

No promises we can't keep, just how the system is built. The privilege story is persuasive because it is accurate.

  • Runs on-premise.The models execute on the appliance's own hardware, inside your office.
  • Not transmitted to external services.Your documents and prompts are processed locally, not sent to an AI vendor.
  • The firm owns the hardware.No metered cloud bill, no third party holding a copy of your files.

No "unhackable", "military-grade", or specific certifications (SOC 2 / ISO) unless confirmed in writing. Legal Box keeps data on-premise so the firm can meet its own obligations; the obligation remains the firm's.

§07 · Sized to your firm

Right-sized on a call, not picked off a menu.

Legal Box scales from a single unit to a multi-unit cluster. The right size comes down to the work you need it to do, which we figure out with you on a call, not from a spec table.

§09 · Questions

The questions firms actually ask.

Does anything ever leave our network? +
The appliance runs on-premise and is operated air-gapped. Your documents and prompts are processed on its own hardware and are not transmitted to any external service.
What happens if it breaks? Who supports it? +
Legal Box arrives configured and supported. Support terms and response handling are covered in the consultation.
Do we need dedicated IT staff? +
No. It's an appliance, not a DIY rig. Your IT lead or outsourced provider can sanity-check it, but it's built to arrive working rather than to be assembled.
Can we try it before we commit? +
That's what the consultation is for. We'll walk through your firm's needs and how Legal Box would fit before anything is purchased.
What does it cost? +
The hardware is a one-time purchase that you own outright, with no per-seat or per-token cloud billing. Customer service and any custom apps your firm needs are charged separately. We size and price it all to your firm on the call.
