On-premise AI for confidentiality-bound firms
Use AI on your client files.
Without sending them to anyone.
Your team wants AI to search contracts, summarize discovery, and catch deadlines — but pasting privileged material into ChatGPT or Copilot hands it to a third party, against your duty of confidentiality and most client NDAs. A Private AI Vault runs entirely on a machine your firm owns: you get the AI, the data never leaves the building.
- 100% on-premise
- Zero cloud inference
- NDA + BAA signed

The problem with cloud AI for lawyers
ABA Model Rule 1.6 binds you to protect client confidences. Putting privileged documents into a third-party AI cloud means a vendor — and anyone who can subpoena or breach them — can reach your client's data. Many firms have simply banned staff from using ChatGPT on client matters, which leaves your most sensitive, highest-value work with no AI at all.
What it does
An assistant that reads your documents — and cites every answer
Drop your files in — contracts, case files, NDAs, discovery, depositions — and your team asks questions in plain English. Every answer points back to the exact source document.
Cross-document clause review
“Which active contracts auto-renew, and what's the notice deadline?” — answered across hundreds of files in seconds.
cited → 3 agreements · §RenewalDeadline & docketing
Pull every date, statute-of-limitations, and renewal window out of a matter folder — nothing buried on page 40.
cited → Matter 04 · datesIssue-spotting
Surfaces clauses worth a second look — e.g. a non-compete that may be unenforceable in your jurisdiction — for a human to decide.
cited → Empl. Agmt · §7Summarize & draft
First-draft summaries of long documents, intake memos, and deposition digests — with the source line for every claim.
cited → 60-pg dep · summaryIt's an assistant, not a lawyer: it finds, summarizes, and flags — your attorneys keep judgment and sign-off.
The privacy guarantee — in writing
- ✓The AI model and the search index run 100% on-premises. Localhost-only by design — it works with the network cable unplugged.
- ✓Zero cloud inference. No API keys, no per-query data leaving, no training on your data, no vendor to subpoena or breach.
- ✓Each client or matter can be an isolated vault — walled-off, separate indexes.
- ✓NDA and BAA signed before anyone touches a file.
Who it's for
Firms where confidentiality isn't optional — typically 5–30 attorneys whose clients require data to stay off third-party AI. If you're comfortable pasting matters into cloud AI, you don't need this; it's built for firms that can't.
- Intellectual property
- M&A
- Healthcare
- Criminal & family
- Government contracts
- Any NDA-bound practice
Engagement & pricing
No per-seat fees. No usage metering. No surprise cloud bills — because there is no cloud.
Why me
I'm a privacy-first engineer who runs this exact stack daily — local AI models, encrypted storage, zero-telemetry tooling. I don't resell someone else's API; I build on-premise systems where your data staying yours is the entire point. Start with a no-cost assessment of where your firm is currently exposing data to cloud AI — then a live demo on documents you choose, on a machine you control, with the Wi-Fi off.
