The cost of slow legal intake

Your firm's biggest cost is not associates. It’s the clients you lost last Friday.

33%[1]

of firms respond to a prospective client's inquiry at all. They don’t go to a better firm, they go to a faster one.

A prospective client submits an intake form. Your office is closed. They need legal help urgently, so they contact two other law firms at the same time. Monday morning your team calls back. The client has already retained someone else.

Retyping

what the intake form already answered, every single consultation. Attorneys spend billable time on repeats.

The attorney opens the meeting with: “Let’s start from the beginning.” Twenty minutes in, they’re collecting the same information the intake form was supposed to capture. Workflows stall before billable work even begins.

35%[2]

of client recommendation rate industry-wide, down from 69% four years ago. Referrals used to be automatic, for most firms, they aren't anymore.

A client whose case is pending hasn’t heard from the firm in three weeks. They assume they’ve been forgotten and call a competitor. By the time your legal team follows up, the relationship is damaged. Or gone.

Unbilled

time that disappears into admin before the real work even starts, every lawyer, every day. That's payroll spent on nothing billable.

The firm wants to grow 30% next year. More clients means more staff. More intake calls, more scheduling, more follow-up. Streamlining your work isn’t optional anymore. It’s survival.

[2] BTI Consulting: client recommendation rates fell from 69.1% (2020) to 35% (2024).

ARIA does not replace your team. It eliminates the part of their work that was never meant to be their job.

Legal AI built for every role in your practice

One AI. Six practices.

Litigators

Every case file analyzed. Every citation verified. Before opposing counsel finishes reading the complaint.

ARIA processes research, flags risk, and routes work, learning from every attorney decision until the first draft is already the right draft.

  • Legal research across case law, statutes, and filings routed to the right attorney by matter type
  • Document review with pre-populated summaries and issues flagged before human review begins
  • Risk monitoring across all active case files, with explanations, not just alerts
  • Pattern recognition from historical matters, improving accuracy with every override

Legal AI outcomes

Real results. No fabricated metrics.

Faster response Fewer lost clients

A prospect who submits at 6pm on Friday gets a response before they contact a second firm. The conversation that used to happen Monday now happens in 90 seconds.

Smarter consultations Higher conversion

Attorneys who walk in prepared close more often. ARIA delivers the full intake summary before the meeting starts, so the first conversation is about the case, not the intake form.

Consistent follow-up Better retention

Clients rarely leave over the outcome. They leave over the silence in between. ARIA puts every active client on a communication cadence, so no one goes dark. Retention holds and referrals follow.

FAQ’s about legal AI assistant ARIA

Fair questions. Straight answers.

What is ARIA AI Legal Assistant?

ARIA is an advanced AI legal assistant built exclusively for legal services, not adapted from a general-purpose tool. It helps legal teams analyze documents, summarize case files, automate intake, and manage client communication. ARIA brings the full power of artificial intelligence to legal practice without compromising the standards your practice is held to.

What are the benefits of using an AI legal assistant in a law firm?

Law firms using AI legal assistants save time on research, drafting, and document review, freeing attorneys for higher-value work. Routine tasks like intake, conflict checks, and client follow-up run automatically. Document analysis that once took days takes minutes. And unlike generic AI, tools built specifically for legal work keep sensitive data secure, citations traceable, and attorney-client privilege intact.

How is ARIA different from using ChatGPT for legal work?

ChatGPT is a general assistant. ARIA is an agentic AI built specifically for lawyers. It connects to approved legal sources, firm knowledge, and workflow rules, and it is governed by AI principles that general tools ignore. It does not just generate text. It helps lawyers analyze documents, verify citations, and produce outputs that hold up under scrutiny.

Why should you trust what ARIA tells you?

ARIA is built on verified legal sources, not open web data. Every answer is traceable. Unlike generic AI tools, ARIA's legal features are designed to surface authority, flag uncertainty, and keep lawyers in control of every decision. The core design principle is simple: help lawyers do better work, not replace their judgment.

How does ARIA keep sensitive case files and client data safe?

ARIA is designed to be secure at the architecture level. It is built to run inside your environment so your data stays under your control, attorney-client privilege is respected at every layer, and bar ethics rules on AI use are addressed before a single line of code ships. ARIA helps you modernize your practice without trading confidentiality for convenience.

What is the ARIA cost, and what's included?

ARIA is priced based on firm size, practice area, and the AI features your team needs. Each implementation is configured around your systems, workflows, and governance requirements. Contact us for a tailored quote that fits your legal services model and growth stage.

How do I get started with ARIA?

Getting access starts with a short discovery call. From there, ARIA is configured to your firm's environment and integrated with your existing stack. Pilot workflows can launch in weeks, and broader rollout depends on integration scope. It is designed to reduce implementation overhead, not add another disconnected tool.

What types of legal documents can ARIA analyze?

ARIA is built to analyze documents across the full spectrum of your work: contracts, briefs, pleadings, deposition transcripts, regulatory filings, case law, and more. It can summarize lengthy files, extract key clauses, and surface relevant precedent, giving you faster, sharper insight from every document it touches.

Can I upload discovery documents, exhibits, and case files into ARIA?

Yes. ARIA is designed to handle high-volume, sensitive material. Upload discovery documents, exhibits, and full case files, and let ARIA summarize, organize, and surface what matters. All uploads are processed inside your secure legal environment, with confidentiality and data protection built into the architecture rather than left to policy.

What sets ARIA apart from other AI tools for lawyers?

Most AI tools are built for general use and adapted for legal work after the fact. ARIA is an agentic AI assistant for lawyers from the ground up. It is trained on legal sources, governed by AI principles specific to legal practice, and designed to produce outputs that attorneys can actually rely on and act from.

How long does it take to implement ARIA Legal AI?

Implementation is faster than most firms expect. ARIA integrates into your existing workflows without disrupting day-to-day operations. Firms typically go live within two to four weeks. The goal is to help you adopt AI without the overhead, and start saving time from the very first matter.
