3 Best AI Tools for Law Firm Client Intake
Smith.ai AI Receptionist
Best for inbound voice intake with documented handoffFrom $95/month for 50 calls · 24/7 Live Agent Network · Clio, MyCase, PracticePanther, Lawmatics, Filevine integrations
Smith.ai is the strongest pick for law-firm client intake when your priority is an inbound receptionist-style workflow with documented handoff. The 24/7 Live Agent Network provides human fallback for calls that fall outside AI scope — a critical capability in a legal context where callers may be in crisis, confused, or asking questions that require attorney judgment.
What to verify before buying: Current integration depth for your specific workflow, data retention and transcript handling, exact handoff behavior, and BAA-equivalent data handling terms for your practice area.
Vapi
Best for custom intake flows with technical resources$0.05/min platform fee · model costs passed through at cost · 10 call concurrency at $10/line/month
Vapi is a strong choice if you want to build your own law-firm intake voice agent. It is a platform, not a turnkey receptionist — which means you get flexibility, but you also have to manage the whole stack. The platform fee is only part of the bill; you still account for model usage and the rest of the voice pipeline.
OpenAI Realtime
Best as voice model layer for a custom buildGPT-Realtime-2: $32/1M audio input tokens · $64/1M audio output tokens · Translate: $0.034/min · Whisper: $0.017/min
OpenAI Realtime belongs in the shortlist when you’re building a custom intake agent and need a low-latency voice layer. It is not a law-firm intake product by itself — it needs a full wrapper for intake, routing, and handoff. Pricing anchors help you budget, but they don’t include telephony, orchestration, or compliance infrastructure.

How to Choose the Right Intake Architecture
Inbound-only firm
If the main goal is to catch incoming calls from website leads, referrals, and existing prospects, an AI receptionist is usually the better fit. Smith.ai is the clearest fit in this category from the evidence we have.
Also want outbound follow-up
Confirm with counsel whether your use of AI-generated or cloned voices and your dialing and prior-consent facts trigger TCPA requirements under the FCC’s Feb. 8, 2024 clarification. Talk to counsel before launch.
Need deep case-management integration
Smith.ai documents integrations with Clio, MyCase, PracticePanther, Lawmatics, and Filevine. If your practice runs on one of those, that’s a strong signal. For other systems, verify integration depth before buying.
Care about fully loaded cost
Voice systems split cost across: platform fee, model usage, telephony, concurrency, storage, and transcript handling. Vapi makes this especially clear because its platform price is only part of the stack.
Compliance Checklist for Law Firm AI Intake
AI intake tools at law firms are not just software purchases. They touch confidentiality, ethics, and telemarketing risk.
Treat intake as facts collection, not legal advice
Your intake agent should collect information, not opine on strategy. It can ask about case type, deadlines, contact info, and urgency. It should not tell the caller what the law is.
ABA Formal Opinion 512 (July 29, 2024)
Lays out baseline duties: competence, confidentiality, communication, supervision, fees, candor and accuracy. These duties apply to how the firm uses the tool, not just whether the tool is technically capable.
Privilege and data handling (Heppner caution)
In United States v. Heppner (Feb. 17, 2026), privilege did not attach in a factual setting involving a public generative AI platform. Confirm who can access transcripts, whether transcripts are used for model training, and retention defaults before go-live.
TCPA risk for AI voice in outbound
The FCC’s Feb. 8, 2024 ruling treats AI-generated voices as “artificial or prerecorded voice” under the TCPA. For outbound use cases — reminders, marketing, callbacks — confirm prior express consent requirements with counsel.

FAQ
What is the best AI tool for law firm client intake?
For inbound voice-first intake, Smith.ai’s AI Receptionist is the most defensible top pick based on current documentation. It starts at $95/month for 50 calls, integrates with Clio, MyCase, PracticePanther, Lawmatics, and Filevine, and includes a 24/7 Live Agent Network. For custom intake flows with technical help, Vapi ($0.05/min + model costs) is the strongest platform option.
What is the difference between an AI receptionist and a voice agent platform for law firms?
An AI receptionist is a prebuilt intake system with turnkey workflows, named integrations, and human fallback built in. A voice agent platform (like Vapi or OpenAI Realtime) is a developer tool for building custom call flows. Receptionists are faster to deploy; platforms offer more control but require more setup and maintenance.
What does Smith.ai AI Receptionist cost for law firms?
According to The AI Agent Report’s law-firm intake review (last reviewed May 20, 2026), Smith.ai starts at $95/month for 50 calls. Confirm current pricing directly at smith.ai.
What ABA guidance applies to AI tools in law firm intake?
ABA Formal Opinion 512, published July 29, 2024, lays out duties around competence, confidentiality, communication, supervision, fees, and candor when using generative AI. Law firms using AI intake tools must operate those tools responsibly under these baseline duties regardless of whether the tool itself is “legal.”
Does TCPA apply to AI intake at law firms?
For outbound workflows, yes. The FCC’s February 8, 2024 ruling clarified that AI-generated voices are treated as an “artificial or prerecorded voice” under the TCPA. If your intake system makes outbound calls for reminders, marketing, or callback campaigns, you need to think about TCPA consent and prior express requirements. Inbound-only systems have a simpler compliance picture but are not automatically risk-free.
How should law firms handle privilege when using AI intake tools?
In United States v. Heppner (Feb. 17, 2026), the court found privilege did not attach in a factual setting involving a public generative AI platform. This is fact- and posture-dependent, not a universal rule. Law firms should confirm in vendor data processing and retention policies: who can access transcripts, whether the vendor uses transcripts for model training, retention defaults, and deletion controls. Keep sensitive details minimized until controls are in place.
