The Problem

Law firms are bleeding time and money on processes that should have been automated years ago.

Every day, your team loses billable hours to manual intake, redundant research, and disconnected systems. Your competitors are quietly building AI into their workflows. Most managing partners know this but don't know where to start — or who to trust.

What We Build

Three systems that change how your firm operates.

Practice Intelligence

AI-powered insights across every matter, deadline, and document. Know what your firm knows — instantly.

Systems Integration

Clio, ChatGPT, Claude, your intake forms — connected into one intelligent workflow. No more tab-switching.

Firm Automation

Client intake, billing, follow-ups, and reporting that run themselves. Your team works on law, not logistics.

Who's Behind This

“I spent 15 years practicing law before I realized the biggest inefficiency in every firm wasn't the lawyers — it was the systems they were forced to work inside.”

I'm a lawyer who codes. I've built Clio integrations, AI-powered intake systems, and custom automations for my own practice and others. Lexnaut isn't a consulting deck — it's the playbook I've already run.

Based in Miami. Working with firms across the country.

How It Works

From assessment to transformation in three phases.

01

AI Readiness Assessment

We map your firm's current workflows, tech stack, and pain points. You get a clear-eyed report on where AI can make an immediate impact — and where it can't. Free, no obligation.

02

Custom System Blueprint

We design the specific integrations, automations, and AI tools your firm needs. Not a generic proposal — a buildable architecture tailored to your practice areas, team size, and existing systems.

03

Build, Train, and Navigate

We implement everything, train your team, and stay on as your navigator. AI isn't a one-time install — it's a practice. We make sure it sticks.

Common Questions

What firms ask before they start.

What is an AI readiness assessment?+
A free 30-minute evaluation of your firm's current workflows, tech stack, and pain points. You get a clear report on where AI can make an immediate impact — and where it can't. No pitch deck, no obligation.
How can AI actually help my law firm?+
AI can automate client intake, accelerate document review, streamline billing and follow-ups, and connect your existing tools into intelligent workflows. Firms using AI report significant time savings per attorney per week and faster document review cycles.
Do you integrate with Clio?+
Yes. We build custom integrations with Clio, along with AI tools like ChatGPT and Claude, your intake forms, and other systems — connected into one intelligent workflow. No more tab-switching.
Who is Lexnaut for?+
Solo and midsize American law firms ready to modernize. Whether you're a solo practitioner drowning in admin work or a managing partner at a growing firm, we build systems tailored to your practice areas, team size, and existing tech stack.
What makes Lexnaut different?+
We're founded by a lawyer who codes. 15 years in practice, plus hands-on experience building real AI systems — Clio integrations, AI-powered intake, custom automations. This isn't a consulting deck. It's a playbook we've already run.
How long does an AI transformation take?+
A single integration can be live within weeks. A full firm transformation — practice intelligence, systems integration, and automation — typically unfolds over 2-3 months, including training and change management.
