Built for privileged work.

Client confidentiality is the job. Corpus is built so you never choose between the best model and keeping a matter private, and on Enterprise it runs inside your own infrastructure.

Your data stays yours

No training, ever
Your documents, prompts and outputs are never used to train any model, ours or our providers'.
Zero data retention
Our model providers process requests without retaining them.
You decide what goes in
Only the files you add to a matter are read. Delete them and they are gone from the matter.

Protected at every layer

Encrypted at rest and in transit
Documents, data and backups are encrypted. Databases sit in private networks with no public access.
Every firm walled off
Each firm's documents, library and matters are isolated from every other firm, and adversarial tests check that the walls hold.
Hardened infrastructure
A managed web application firewall, rate limiting, private networking and protected backups, run to enterprise data-security standards.

The right people, nobody else

SSO and roles
Sign in with your identity provider. Owners, admins, billing and members each see only what their role needs. Billing sees spend, never matter content.
Invite-only access
There is no public sign-up. Every firm is provisioned by a person on our team.
Audited operator actions
Every action our own operators take is written to an append-only audit trail.

Every change accountable

Tracked, not overwritten
Every edit Corpus makes to an existing document is a Word tracked change, attributed to the agent.
Every version kept
Drafts, imports and accepted states are saved as versions you can open or compare at any time.
Ask cannot edit
Ask mode is read-only by construction. The editing tools are not available to it.

Your cloud. Your rules.

On Enterprise, we deploy Corpus into your own cloud or private environment, so documents never leave infrastructure you control. We work with your security team on the review, the questionnaire and the controls you need, and we build the custom features your practice relies on.

Questions from your security team? Bring them.

We'll walk your IT and risk teams through how Corpus handles client data, end to end, and answer the questionnaire with them.
