Your documents. Your AI. In your office.

A private AI box in your family office reads your papers, answers questions in plain English with the page behind every line, and shows how everything connects. The AI runs on the box: no cloud AI.

Sample archive of a fictional family. As of October 11, 2026.

Know which version is in force.

The Chains view lines up wills, trusts and powers of attorney by date. See which version counts, what replaced the old one, and what was in force on any past date. A paper not shown to be signed is marked, not assumed.

Chains view: As of October 11, 2026: 7 of 7 chains in force; the 2008 power of attorney is revoked. 3 undated drafts of the will, none known to be signed. The 2015 power of attorney revoked the 2008 one; the will has a 2014 codicil and three undated drafts of a second codicil, none known to be signed.Beneficiary designationIRAin forceIRA designation 2012Beneficiary designationLife insurance policyin forceLife insurance designation 2006Health care directiveRobert A.

Find problems nobody asked about.

Document health keeps checking the archive for problems. Here, a life policy still names a wife who died in 2008, and a second codicil exists only as unsigned drafts. Vault shows the evidence and leaves the decision to you.

Document health: four open findings. The selected conflict says beneficiary designation SL-2006-0419 still names Eleanor M. Hale, who died on 2 November 2008. Two quotes are checked against the page. Below it, three drafts in the will’s chain, none shown to be signed, a scan held for labels and 31 scans with poor OCR.

Ask in plain English.

Ask the way you would ask a colleague. The answer reads like a memo. Every line cites its page, and each quote is checked word for word against that page before you see it. When the papers don’t settle a point, it says so rather than guess. It helps you find and check; it is not legal advice.

The question “Who can act for Robert if he is in the hospital?” and its answer: Margaret E. Hale is his health care agent and his agent under the 2015 durable power of attorney; Daniel J. Hale is the alternate and Imogen Reyes the successor agent. Six of six quotes match the page. Below, the source rows from the 2015 health care directive; a side list shows the facts the answer used.

It stays in your office.

The AI runs on the box: no cloud AI. You decide who sees what.

One box, in your office.
Vault runs on one computer on your premises, and the AI that reads and answers runs on it too.
No cloud AI.
Your papers and questions are never sent to an outside AI provider. An off-site backup copy is off unless you turn it on, and it is encrypted before it leaves.
Each person sees only what you allow.
Give an adviser the papers for her matter and nothing else. “View as” shows exactly what she sees, with no hint that other papers exist.
Every document opened is logged.
Each one is recorded in a tamper-evident log.

We look after it.

We set it up.
Custodia installs the box and supports it, on site or remotely by appointment.
It doesn’t depend on us.
The box doesn’t need our servers to search or answer, so it keeps working without us. You would stop getting updates.
Hardware cover.
The box carries the maker’s one-year warranty. We agree replacement times with you in the contract.

On our roadmap

Not available yet. These are planned, not part of Vault today. We’ll tell you plainly what a pilot includes.

  • Translation

    Read a document written in another language in English, on screen.

  • Picture search

    Find photographs and plans by what they show.

  • Drafting

    Draft letters and memos from the archive, with the same page citations.

  • Ongoing intake

    One-way intake from laptops, the office scanner and email.

  • Deadlines

    Renewal dates, expiring grants and other deadlines, on a calendar.

  • Briefs

    A short written brief on one question, with its sources.

  • Adviser packs

    A packet of the papers one adviser needs for one matter.

  • Financial figures

    Holdings and figures across entities, read from statements.

Common questions

Does it go online?

It has no public internet address, and the AI that reads and answers runs on the box, with no cloud AI. The box does connect out for software updates and the clock and, only if you switch them on, an encrypted off-site backup and remote support. We walk your IT team through every connection it makes.

What files can it read?

Word, Excel, PDFs, email, images and old scans, in English, German, French, Italian, and Spanish. An English question finds a document written in Italian. A poor scan can still be searched, but Vault won’t quote it in an answer until a better copy is on file.

Who sees what?

Each person sees only the papers you allow. Before you invite someone, “View as” shows you their view. Every view is logged.

What hardware does it need?

One compact computer in your office, which we configure for you. It joins your office network. There is no cloud account to set up.

How do documents get in?

We load your archive with you during setup, from folders or drives, starting with your most important documents. You can watch it read, and search what is done while the rest continues.

What does it cost?

It depends on the size of your archive and who needs access. We give you a fixed quote after a walkthrough.

See it for yourself.

Pilots are starting now. Book a private 30-minute walkthrough over a screen share, on the sample archive, and bring the questions your office gets asked.
