## The choice for law firms

Harvey and CoCounsel are capable, well-regarded legal AI products. They are also cloud services: your documents are processed on the vendor's infrastructure.

If you're weighing an alternative, it usually comes down to attorney-client privilege and the duty of confidentiality — whether privileged matter should leave the firm's network at all.

This is a factual comparison. Both products do real work; the question is where the data is processed and who owns the system.

## Cloud SaaS vs. owned and air-gapped

| | Harvey / CoCounsel | ibl.ai |
|---|---|---|
| **Hosting** | Vendor cloud | Your infrastructure — air-gapped if needed |
| **Privileged data** | Processed by the vendor | Never leaves the firm |
| **Model** | Vendor's chosen model | Model-agnostic, including open-weight |
| **Pricing** | Per seat | Flat-rate, unlimited users |
| **Code** | Closed SaaS | Full source code ownership |

## Why architecture beats assurance for privilege

ABA Model Rule 1.6 requires reasonable efforts to prevent unauthorized disclosure of client information. "We use a vendor that promised not to look" is a weaker position than "the matter never left our network."

An air-gapped deployment makes the confidentiality question architectural, not contractual. Open models now handle research, review, and drafting at a level that was cloud-only two years ago, so the firm no longer trades capability for control.

## What attorneys run

A contract review agent that redlines against your playbook, a legal research agent grounded in your own briefs with verified citations, a client intake agent that screens and books — all inside the firm's boundary.

This is the model behind [air-gapped AI for law firms you own](/solutions/legal), built on the [Agentic OS](/product/agentic-os), with full code ownership and client data that never leaves your infrastructure.

## Where to start

Pick one workflow with clear value and low risk — internal knowledge search or first-pass contract review — and run it air-gapped against a single practice group. Prove the privilege model on real matters before expanding.
