More consultations booked and fewer calls for your staff

Each call ends with a defined outcome, like a new client's intake saved, a signing booked, a matter update given, or a payment link sent.

The agent collects what happened and who else is involved, runs your conflict check, and saves the intake for your attorneys to review.

AI for law firms, from the first call to the paid invoice

What does AI for law firms do on the phone?

AI for law firms usually means drafting and research software. This page covers the phone. A law firm voice agent takes intake, books consultations and signings, updates clients from your staff's notes and texts a link to pay an open invoice. It doesn't draft, research or review anything.

What happens when a new client calls after a car accident?

The agent takes their name, the other parties and what happened while your staff stay on other work. It runs your conflict check against your matter records, saves the intake for attorneys to review, then offers to book a consultation.

I was hurt in a car accident last week and I need a lawyer.

I'm sorry to hear that. What's your name, and who was the other driver?

Nadia Brooks. The other driver was Carl Hensley.

Is this an AI receptionist for law firms?

Yes, and it sits next to the AI tools for law firms your attorneys use on documents. Returning clients are found by phone number, confirmed, and hear only the note your staff left. Signing times come from the firm calendar, and the agent books after a yes.

Where do AI voice agents for law firms stop?

At legal advice. The agent says up front that it can't give any, then transfers questions about rights, deadlines or a case to firm staff. That includes quiet ones, like whether to sign before changing a beneficiary. You decide which systems it can use.

Resolved on the call

Did the agent resolve the client's request before the call ended, without a transfer?

The work a voice agent takes off a firm's main line

Intake, signings, client updates and invoices all run through the same phone number. These are the calls where staff get time back and where the agent hands off.

Conflict checks start during intake

The agent gets the other parties' names while the caller is on the line and checks them against your matter records, so attorneys open an intake that has already been run.

Status calls get answered from your notes

A client asking about trust documents hears the latest note your staff left on the matter, and can book the signing on the same call.

Signings land on the firm calendar

Open times come straight from the calendar. The agent reads the choice back, books after a yes, and reminds the client to bring photo ID.

Invoice links go out by text

With the client's okay, the agent reads the open invoice and texts a secure link. Your billing staff skip the call, and the client gets a receipt once it's paid.

Clients are confirmed before a note is read

Finding a number isn't the end of it. The agent checks it's speaking with that client, then reads the note on the matter and nothing else from the file.

Legal questions go to your people

No opinion on rights, deadlines or a case, ever. Those calls transfer to firm staff. The agent also won't touch a document, so your drafting tools stay where they are.

Built for calls that swing from car accidents to signing times

One minute it's a new client and a stranger's name to spell, the next it's an invoice number. Cartesia's speech models handle both on the same line.

Gets the names right

Conflict checks depend on the other party's name. The agent gives callers room to spell it and doesn't talk over them while they find an invoice or a reference.

Your choice of LLM, your firm's tools

Conflict checks, client lookups, signing bookings and invoice reads are tools the LLM calls mid-conversation. You pick the model, and legal questions transfer to firm staff.

One voice for the whole firm

Set one library voice for the firm, and an estate client and an injury client both reach the same steady front desk.

Three ways a firm covers its main line

An AI receptionist for a law firm competes with the desk you have and the service you might hire. Here's how the three compare on a firm's actual calls.

Law firms FAQs

What can AI for law firms do on the phone?

A law firm voice agent takes legal intake from new callers, books consultations and signings, updates clients from the notes your staff leave on a matter, and takes invoice payments. You decide which systems it can use and what it's allowed to do.

Can the agent run a conflict check during intake?

Yes. During client intake the agent collects the names of the other parties and checks them against your matter records before it saves the intake for your attorneys.

Can the agent give legal advice?

No. The agent says it can't give legal advice and transfers questions about rights, deadlines, or a case to your staff.

Can the agent take invoice payments?

Yes. The agent reads the open invoice and texts the client a secure link to pay it.

Can Cartesia work with our practice management system?

Yes. The agent connects to your practice management system, calendar, and billing through tools you configure.

Can an agent hand a caller over to a person?

Yes. The agent can transfer calls to your team, and you control exactly when it does.

Which AI is best for law firms?

That depends on the job, because no single AI covers a whole firm. Drafting and research call for one kind of tool, and the phone calls for another. For calls, check that the agent runs intake, stays out of legal advice and transfers to your staff. You can call the sample law firm on this page and ask it whether you have a case.

What AI tools are approved for law firms?

Your firm decides that, along with whatever your bar's rules ask of you, and Cartesia can't approve a tool on your behalf. To help that review, this agent says it is an AI, refuses legal advice, records and transcribes every call, and uses only the systems you allow. Cartesia's security badges are SOC 2 Type 2, GDPR and HIPAA compliant.

Who offers the best AI for law firms?

No single vendor offers the best AI for every job in a firm. Some companies sell drafting and research tools, and Cartesia sells voice agents for the phone. If calls are your gap, try the sample law firm on this page and compare it with how your front desk handles intake today.

What is the best legal AI software for law firms?

The best legal AI software for a firm fits the work you most need covered, so start there. For the phone, look for intake with your conflict check, no legal advice and a clean transfer to staff. This agent does those, and it doesn't draft or research documents.

How much does a law firm voice agent cost?

A law firm voice agent is $0.03 per minute of call time, so a quick invoice call costs less than a long new-client intake. LLM usage is billed separately. A Cartesia phone number adds $0.014 per minute, or nothing if you bring your own Twilio account or SIP trunk. The free plan includes $1 of agent calls a month, so you can test the agent before you pay. See pricing.
