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
- Works offline
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.
