Proof is the practice

Every firm has AI now.
Few assume that you do too.

We assume it, and we built the practice around it. Smartness stopped being a moat. It is table stakes.

What cannot be downloaded is proof: where your data ran, that every citation survived byte-for-byte checks, and a named lawyer accountable for all of it.

It answers machines too. Bring your own agents and ours answer. Everything here is checkable, starting with how we use AI on your matters.

The Mirror

Our use of AI. Your use of AI.

We publish our AI posture and expect you to have one too. Working with us is two-sided by design.

Our use of AI

Your data never leaves. Privileged work runs on hardware we own.

A hard technical floor. Privileged work is refused external routing; the refusal is logged.

Byte-verified citations. Every citation is checked against its source before a human relies on it.

Benchmarked, not vibes-tested. We measure our tooling on a gold corpus with known defects.

A lawyer signs everything. AI drafts; a licensed attorney signs and carries the accountability.

A cost, not a fee. Flat subscription pricing; machine time is never billed as hours.

Your use of AI

Expected, not merely tolerated. We built the engagement around your AI.

01

Draft with our prompts

Have your own AI draft first, using the prompt library we publish.

02

Upload it into privilege

The draft lands in your privileged workspace on our hardware.

03

Our agents meet your agents

Our agents challenge it, citations are byte-verified, a licensed lawyer signs the result.

Start with the prompt library

Then pick your level of control

Same stack, three levels. Climb when ready.

01

Safer-space portal

Work in a privileged workspace on our infrastructure; zero setup.

02

Managed sovereign cloud

A dedicated instance in a region you choose, operated by us.

03

Full self-host

The whole stack on your hardware, with our own runbooks.

Every rung runs the same verification lights.

The Third Leg

Your agents, our agents

Paid-tier clients can point their AI agents at our Agent Gateway (MCP or plain REST): your agents call ours from inside your automations. Same trust architecture, machine-to-machine.

Two classes, one honest line

Class S: self-serve tooling

Runs autonomously: matter status, document intake, checklist drafts.

Output is machine work-product, watermarked “DRAFT — work-product tooling; attorney review pending; not legal advice”.

Class A: attorney-signed

Your agent files the request and gets a ticket with an honest ETA.

A licensed attorney signs before release; the result returns by webhook or polling.

Drafts are labeled as drafts. Signatures come from lawyers.

The rails it runs on

Keys you control. You issue and revoke credentials from your portal, scoped to your matter alone.

The same 403 wall. Privileged content is refused external routing, and every call is logged.

No meter. Included in your flat plan up to a monthly allowance; never per call.

Watch the loop close: your agent files a request, a lawyer signs, the result returns by webhook. Full gateway disclosure lives at /ai.

The Market, Mapped

Two questions sort the whole market

Who controls the AI? Are you buying a tool, or accountable counsel?

AI-forward firms on vendor clouds

Accountable counsel, someone else's computers.

Accountable counsel on sovereign AI

North End Law

A licensed firm, its own hardware, the proof to show for it.

AI tools on vendor clouds

Nobody signs; your data lives with the vendor.

Self-hosted tooling

You control the hardware and inherit the accountability.

Adversarial Verification

Agents that check each other

We do not ask one model to be right; we make several disagree. Reviewer agents draft; challenger agents attack. An independent Citation Engine verifies every quote byte-for-byte.

Disagreements go straight to the signing lawyer. The pipeline is measured on a gold corpus, so "it works" is a number, not a feeling.

In law, the second opinion is the product.

Ask any firm these four questions

Then ask us. Our answers are published, logged, and auditable.

1. Which AI vendors receive our documents?

2. Can you prove it?

3. How do you catch AI errors?

4. Who is accountable?
