Private beta

Legal AI on your desk.

Private by physics, not promise.

Cortex is a device that plugs into your computer and gives your firm a private AI workspace: organize your matters, draft, review, and research. Your clients’ data never touches the internet, because the device never does.

The Cortex device
No internet. Nothing uploads, nothing syncs, nothing leaks.

The problem

Cloud AI says trust us.
Cortex says you don’t have to.

Every legal AI so far asks the same thing: send your clients’ files to our cloud, and trust our promise to protect them. They’ll give you certifications, zero-data-retention agreements, audits, every assurance on paper.

Cortex just sits and works, right in front of you.

The proof

AI that never leaves the office.

The intelligence does all its work right beside you, sealed by the device itself.

Sealed
No internet access. Nothing uploads, nothing syncs, nothing leaks.
Encrypted
Everything lives on the device, unlocked only by you.
On your command
Software and legal-corpus updates run only when you start them, from your machine.
THE INTERNET no way in or out YOUR OFFICE Your computer Cortex

Setup

Plug & Play. Set up in minutes.

Plug it in, set a password, and start working. No IT project, nothing to configure.

In your documents

Helpful, right where you work.

The assistant is just there, in the word processor you already have open, in the toolbar, in a comment, on whatever you’ve got selected. Ask it a question and it answers where you asked. Have it proofread. Or turn it loose to read a draft and leave its own notes, like a second set of eyes that never gets tired.

In your portal

Powerful, at your direction.

When there’s real work to organize, the portal is where you run the show: every matter in one place, prebuilt workflows or ones you shape yourself, and agents to handle the routine passes. You’re the partner. Cortex is the associate that never sleeps.

The Cortex portal, organized around your matters

Two ways in, one private AI, and nothing you touch ever leaves the device.

Overnight

It works while you sleep. And never sends you a bill for it.

The cloud charges by the token, because you’re renting someone else’s machine by the minute. Cortex is yours. Hand it the long jobs at the end of the day, review a hundred contracts, summarize a deposition, and it works through the night on its own GPU. In the morning the work is done, and it’s ready to do what’s next.

The advantage

Focus on using AI, not configuring it.

Running capable AI on your own hardware used to mean choosing models, wiring up tools, and babysitting infrastructure. ArcQi did all of that and sealed it in a box. You just work.

Scale

It grows with you.

Start with a single box. Add more as your firm grows.

Multiple Cortex boxes added as a firm grows

The assistant every lawyer wants, that never leaves the office.
