§01 · The promise
Attorney–client privilege, preserved.
Legal Box runs large language models over your firm's own documents, on an appliance that sits in your office. No cloud AI, no LLM API, no vendor with a copy of your files. As private as a locked filing cabinet.

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.
Document drafting
First drafts of agreements, letters, and memos from your firm's own templates and precedents, in your firm's voice. Save the prompts that work as one-click workflows your juniors can re-run: CP checklists, change-of-control reviews, credit-agreement summaries. It also works inside Microsoft Word: a task pane, served by the appliance itself, drafts and inserts at your cursor without the document leaving the office.
Document review
Read, summarize, and flag across long documents, or extract across hundreds of files at once into a tabular review. Every answer is cited back to a page and a quote, so nothing is taken on trust.
Document management
Matter-scoped projects that keep full context across every conversation and document. Search, organize, and answer questions across your firm's entire corpus, with nothing indexed or stored offsite. Generated drafts land as new versions with the full history kept; originals are never overwritten.

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.
- Documents stay on the appliance
- Every prompt processed on-premise
- Unlimited use, no per-call or metered billing
- No client data transmitted to a third party
- 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
A configured appliance you plug in, not a project to babysit.
Legal Box is a self-contained appliance, pre-configured and supported. It arrives working.
Plug it in
The appliance sits in your office or server closet and joins your network. No external accounts to create.
Point it at your files
It ingests your firm's own documents (case files, contracts, precedents) entirely on-device.
Work, fully private
Your team drafts, reviews, and asks questions. Nothing it processes ever leaves the building.
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.
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 AI 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.
- ✓One appliance, the whole firm.Every lawyer signs in with their own account, held on the appliance — no external identity service. Matters, reviews, and workflows are shared person-by-person, so colleagues see only what they're given.
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.
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.
