Build a Voice AI System to Qualify and Follow Up With Legal Leads
The best voice AI for legal leads is a custom system built on a large language model like Claude. It replaces generic auto-dialers with conversational agents that qualify leads and schedule consultations.
The system's complexity depends on your existing software. A law firm using a modern CRM like Clio Grow with a well-defined intake process is a standard build. A firm using a legacy case management system with an undocumented API requires more discovery and custom integration work.
We recently built a voice AI for a 7-attorney personal injury firm that was receiving 300 web leads per month. Their intake team could not follow up fast enough. We launched the system in 4 weeks, and it increased their rate of qualified consultation bookings by 40% in the first month.
What Problem Does This Solve?
Most law firms try to solve lead follow-up with generic tools that fail. Cloud phone systems like RingCentral offer basic call routing but cannot hold a conversation to qualify a lead. They can forward a call, but they cannot ask, "Have you already spoken with another attorney about this matter?"
A common next step is attempting to use a no-code tool to connect a web form to Twilio. This breaks down immediately. The workflow is static; it can place a call, but it cannot understand the outcome. It cannot distinguish a voicemail from a live answer, handle a request to call back later, or send a follow-up text message. There is no logic for retries or for capturing the reason a lead is not qualified.
This forces the intake team back into manual work. A 10-person firm using a lead provider gets form submissions by email. The goal is a 15-minute response time, but the intake coordinator is often busy with other tasks. By the time they call, hours have passed and 70% of calls go to voicemail. The lead has already moved on.
How Does It Work?
We begin by mapping your firm’s exact intake questions into a conversational script powered by the Claude API. This script guides the AI agent. We provision a dedicated phone number using Twilio and build a custom application with Python and FastAPI to manage the call logic. The entire system is deployed on AWS Lambda for reliability.
When a lead submits a form on your website or from a provider, a webhook triggers the FastAPI service within 200ms. The service initiates an outbound call. Once connected, the AI agent converses with the lead, using the Claude API to generate responses in real-time. We tune the system for a P95 response latency under 800ms, eliminating unnatural pauses and creating a fluid conversation.
The agent handles complex conversational paths. If a lead has a valid case, the AI can transfer the call directly to your intake team or schedule a consultation. If a lead is not qualified, the agent politely ends the call. The full call transcript and outcome (e.g., 'Consultation Booked', 'Not Qualified - No Injury') are written to a note in your CRM, like Clio Grow or Lawmatics, within 2 seconds of the call ending. This system can handle over 1,000 leads per month.
The infrastructure runs serverlessly on AWS Lambda, typically costing under $50 per month for several hundred leads. We use structlog for detailed logging, making every call auditable. You get a daily Slack summary of calls made, connection rates, and appointments set. A complete build takes 3-4 weeks from kickoff.
What Are the Key Benefits?
Engage Every Lead in Under 60 Seconds
Our system calls new web leads in under a minute, 24/7. This immediate follow-up increases contact rates by over 50% compared to manual calling.
No Per-Agent, Per-Minute Pricing
You pay a one-time fixed price for the build and direct infrastructure costs after. This avoids the recurring per-seat fees of call center software.
You Own The Code and The System
We deliver the complete Python source code to your firm's GitHub repository. You are not locked into our service and can have any developer extend it.
Real-Time Transcripts in Your CRM
Every conversation is transcribed and logged directly in your case management software. You can review the AI’s performance and audit any interaction.
Integrates With Legal-Specific Tools
We build direct integrations for legal CRMs like Clio Grow, Filevine, and Lawmatics. The AI's notes appear natively, as if your own team wrote them.
What Does the Process Look Like?
Scoping and Scripting (Week 1)
You provide access to your lead sources and current intake questionnaire. We map this into a conversational script and confirm integration points for your CRM.
Core AI Development (Week 2)
We build the core voice agent using Python, FastAPI, and the Claude API. You receive audio samples of the AI handling common lead qualification scenarios.
Integration and Testing (Week 3)
We connect the AI to your CRM and provision a phone number. We run a batch of 20-30 test leads to verify call logic and data capture.
Launch and Handoff (Week 4)
The system goes live. After a 2-week monitoring period, we hand over the complete source code, deployment instructions, and a system runbook.
Frequently Asked Questions
- What factors determine the project's cost?
- The primary factors are the complexity of your qualification script and the number of integrations. A straightforward script that integrates with a single CRM like Clio is a standard build. Adding integrations to calendar systems for automated scheduling or to document management platforms adds to the scope. We provide a fixed-price quote after our initial discovery call.
- What happens if the AI misunderstands a lead?
- If the AI cannot understand a response after two attempts, it uses a fallback script: "I seem to be having trouble hearing you. An intake specialist from our office will call you back shortly." Your team receives a Slack alert with the call transcript, allowing for immediate manual follow-up. This ensures no lead is lost due to a technical issue.
- How is this different from a virtual receptionist service like Smith.ai?
- Virtual receptionists are humans who have competing clients and limited hours. Our solution is a dedicated AI agent that works for your firm 24/7. It follows your script perfectly every time and costs a flat infrastructure fee, not a per-call or per-minute rate. It is a software asset your firm owns, not a service you rent.
- Does the AI agent sound robotic?
- No. We use modern text-to-speech APIs that provide natural, human-like voices. We can select from dozens of voice profiles and adjust the tone and pacing to match your firm’s brand. The goal is a professional and warm interaction. Most leads do not realize they are speaking with an AI.
- How do you handle call recording consent and compliance?
- The system can be configured to automatically play a disclosure at the start of each call, such as "This call will be recorded for quality purposes." We ensure the solution complies with federal and state-level consent laws based on your operations. All recordings and data are stored securely in your own cloud infrastructure, not ours.
- Can the AI handle leads who speak Spanish?
- Yes. The underlying models, including Claude, are multilingual. We can build the agent to converse entirely in Spanish or to detect the language being spoken and respond accordingly. Supporting multiple languages is defined as part of the initial project scope to ensure we build with the correct voice models from the start.
