AI is changing legal work. We build the technology and bring the people who help your firm make it part of everyday practice.
Why we exist
The hard part of AI adoption happens inside the firm: understanding the work, connecting the knowledge, and helping people build new habits.
North brings those pieces together. Lawyers work in Claude, supercharged by North OS with their firm’s knowledge and skills. Our Forward Deployed Legal Engineers work alongside them to make it useful in practice.
We stay as your external Chief AI Officer, bringing updates, new features, and custom tools as your firm evolves.
