Private AI control layer

Use the best AI available — without surrendering your client data or your firm's know-how.

Cartulary is a private AI control layer for firms that run on trust. Route work to the best model for each job, under your permissions, your policies, and a complete audit trail.

01

Your team is already using AI. The only question is whether it's under your control.

ENTRY 0001
Claim 01

Unapproved AI use starts before a policy catches up.

Claim 02

Data retention and training terms vary by tool and contract.

Claim 03

Clients, carriers, boards, and regulators increasingly ask for the record.

How it works

ENTRY 0002
Step 01

Your private operating map

Clients, matters, patients, jobs, invoices, and policies sit in a system your firm owns.

records · relationships · policy scope

Step 02

Your AI command center

Permissions, human review gates, reversible workflows, and a full audit log sit between your people and every model.

roles · approvals · reversibility

Step 03

The best model for every job

Route by cost, quality, speed, or privacy. Your firm is never locked into one AI vendor.

Security posture

Proof that can survive review.

Retention

Prompts and outputs are not retained or used to train vendor models where contractually supported.

Permissions

Role- and record-level permissions determine who can use each workflow and what data can leave.

Controls

SOC 2 certification is not claimed here. Control evidence is recorded so diligence can inspect the trail.

05

Every workflow makes your firm smarter — not your vendor's model.

ENTRY 0005
Workflow

A person uses AI inside firm policy.

Captured decisions

Approvals, edits, and exceptions become part of the record.

Richer operating map

The next workflow starts with better firm-owned context.

Working session

Map one sensitive workflow before the next unapproved tool does.

Bring one workflow, one policy owner, and one skeptic. Leave with the operating map, review gates, and audit trail your firm would need before broader rollout.
