Best AI Receptionist for Law Firms in 2026: 5 Options Compared
A law firm's phone is where prospective clients first describe a problem to a stranger. Five options are compared on what each vendor publishes about price, intake, conflict information and case-management software, with an intake script that gives no legal advice and general-information notes on ABA Model Rules 1.6, 1.18 and 7.3.
Disclosure and limits: VantaWeb publishes this page and sells Anna, one of the options, so it is a vendor's comparison and not an independent ranking. The four competitors are listed alphabetically from their own sites as read on 2026-10-17 (method); VantaWeb has its own unranked box. Nothing here is legal advice; ask your state bar or ethics counsel.
Summary
The four others bill four ways: AgentZap per plan with minutes and a setup fee, Ruby per month of live-receptionist minutes, Smith.ai per call (human plans) or per call with a free tier (AI plans), and Upfirst per plan with a call allowance. Legal intake is long, so minutes and calls add up differently.
All four publish material for law firms. Smith.ai's home page is written for them, Ruby has a legal page that describes live receptionists, and AgentZap and Upfirst describe conflict-check details. Pages read; no test calls placed.
VantaWeb, in one line: Anna records intake details and the other party's name, books a consultation to Google Calendar, transfers an urgent call, and emails your office a summary. She runs no conflict check and has no Clio, MyCase or other case-management connection.
What do the ABA Model Rules say about confidentiality?
Rule 1.6(c) says "a lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client". Rule 1.18(b) protects information from a prospective client. States adopt their own versions. General information, not legal advice.
What does an AI receptionist for a law firm cost?
Published entry prices: Upfirst $24.95 a month for 30 calls, AgentZap $109 a month plus a $499 setup fee, Smith.ai $150 a month at $2.00 a call, and Ruby $250 a month for 50 live minutes. Units differ, so price your own call volume under each plan. Checked 2026-10-17.
Does Model Rule 7.3 restrict answering inbound calls?
Rule 7.3(b) bars live person-to-person solicitation of professional employment when a significant motive is pecuniary gain, unless the contact is with a lawyer, a person with a family, close personal, or prior business or professional relationship with the lawyer or firm, or a person who routinely uses for business purposes the type of legal services the lawyer offers.
Why law-firm calls are an intake problem
A lawyer in a deposition or a hearing cannot take a call, and the people phoning are rarely patient: someone served with papers, someone injured last week, someone whose family member has just been arrested. If the call reaches voicemail they dial the next firm. The question for a receptionist, human or AI, is how much of a usable intake it produces before anyone calls back.
Legal calls also carry duties that most trades do not. What a prospective client says in the first minute may already be protected, an off-hand answer from a receptionist can sound like advice, and some calls are time-critical for reasons the caller does not state. A script should therefore collect a few facts, say plainly that the call-taker cannot advise, and stop.
That is why this page compares intake design as much as price: which vendors collect the other party's name for conflicts, who decides whether a matter is accepted, and what happens when a call cannot wait.
How we compared
Method. On 2026-10-17 we read each vendor's pricing page and its page for law firms (linked in the table), recording price and billing unit, what the page says about intake and conflict information, the case-management software named, and languages. "None found" means not seen on those pages. No test calls, demos or reviews; VantaWeb's statements were checked against our voice agent's code, and the rules cited below come from the ABA's own pages.

|---|---|---|---|
| AgentZap | Tiers by monthly minutes: $109 (150), $295 (450) and $899 (1,500), overage $0.85 down to $0.70 a minute, each plus a $499 one-time setup fee; 30-day money-back guarantee | agentzap.ai/pricing | 2026-10-17 |
| AgentZap | Legal page (dated July 18, 2026): describes structured legal intake, conflict-of-interest screening against your client database, and scheduling into Clio, MyCase and PracticePanther; headlines "$109/month flat with no per-call fees" while the pricing page above lists included minutes and overage.

Legal intake triage table and script
The middle column is how firms commonly sort a call; your attorneys decide. The right column is what Anna does once a call is classed. Anna answers inbound calls only here, and no row asks her to judge a matter.
| Caller says | Common handling (your firm decides) | What Anna does |
|---|---|---|
| "I've been arrested" or "my family member is in custody" | Time-critical for criminal defense; reach an attorney at once | If you class it as urgent: cold transfer to the emergency contact; a message if nobody answers |
| "I was in an accident last week" | New matter intake | Records the caller's description in a sentence or two, the date, the other party's name and contact details; books a consultation if a calendar is connected |
| "I have a hearing tomorrow" or "I was served papers" | Deadline-sensitive; same-day attorney call-back | Records the date and details, flagged urgent in the summary; transfers if you class it as urgent |
| "I'm a client; I need to talk to my attorney" | Route to the responsible attorney or assistant | Transfers to the number on the account or takes a message; has no access to case files and does not discuss any matter |
| Opposing counsel, a clerk or a court office calling | Route to the attorney or a paralegal | Takes a name, organisation, call-back number and message, or transfers if you set that |
| "What do you charge?" or "do you handle divorces?" | Answer from approved firm details | Answers only from the practice areas and consultation details you provide; otherwise records the question |
| "Can I sue my landlord? What are my rights?" | The receptionist does not advise | Says she cannot give legal advice and moves to intake |
With no emergency or transfer number on the account Anna cannot transfer and takes the caller's details. She does not accept, decline or screen out a matter, check conflicts or route by service type. A transfer can be cold or, where the account is set to warm, warm; a warm transfer that goes unanswered sends one text to your transfer number.
Sample intake script that gives no legal advice
Illustrative, not a recording. The announcement before a transfer and the apology after a failed one are Anna's actual wording; the rest is what a firm might write with its counsel.
Caller: My landlord won't return my deposit. Can I sue him? What are my rights?
Anna: I'm not able to give legal advice, but I can take down a few details so an attorney can review them and call you back. Is that all right?
Anna: Can I have your name and the best number to reach you, and is it okay to leave a voicemail there?
Anna: In a sentence or two, what is the matter about? Please don't go into more detail than you need to; the attorney will ask for the rest.
Anna: Who is the other party, so the firm can check for conflicts before anyone calls you back?
Anna: [Your firm's disclaimer, as written by your attorneys.] Thank you; someone will call you.
If the caller says "I've been arrested": This sounds like an emergency. I'm connecting you to our on-call team right now. One moment.
If nobody answers: I'm sorry, I wasn't able to reach someone right now. Let me take a message and have them call you back.
Legal intake fields to collect
Collect the minimum a lawyer needs to decide whether to call back, and no more.
| Field | Why it matters |
|---|---|
| Name, call-back number, safe to leave a message | The message fallback records a name, a call-back number and the message; whether a voicemail is safe protects the caller |
| Email, if offered | For the consultation confirmation, if you use one |
| Matter type in the caller's words | Routes the call to the right attorney; keep it to a sentence or two |
| Date of the event and any date the caller mentions | Recorded as stated; the receptionist gives no view on deadlines |
| Other party or parties | The firm's conflict check starts from these names |
| How the caller found you | Marketing attribution |
| Urgency and preferred consultation time | Custody, hearings and arrests change the order of call-backs |
General information on confidentiality and solicitation
Confidentiality: ABA Model Rule 1.6
Rule 1.6 generally bars a lawyer from revealing information relating to the representation of a client without informed consent unless an exception applies, and paragraph (c) says "a lawyer shall make reasonable efforts to prevent the inadvertent or unauthorized disclosure of, or unauthorized access to, information relating to the representation of a client". Rule 1.18 extends a duty not to use or reveal information from a prospective client. For an answering service the practical questions are where call recordings and summaries are stored, who can read them and how long they stay. VantaWeb lists its processors on the sub-processors page.
Solicitation: ABA Model Rule 7.3
Rule 7.3(b) limits a lawyer from soliciting professional employment by live person-to-person contact when a significant motive is pecuniary gain, unless the contact is with a lawyer, a person with a family, close personal, or prior business or professional relationship with the lawyer or firm, or a person who routinely uses for business purposes the type of legal services the lawyer offers. This page describes inbound answering only. Anything outbound, such as follow-up calls or texts to someone who did not ask, is a separate question to settle under your state's version of the rule before it is switched on.
The Model Rules are a model: each state adopts and amends its own, and bar opinions on AI tools vary. This section is general information, not legal advice. Check your state bar's rules and ask your ethics counsel before relying on any vendor.
VantaWeb (publisher of this page): what Anna does on a law-firm line
Anna asks the questions in your script and writes the answers into a summary emailed to the address chosen at onboarding; leads appear in the dashboard. A consultation is booked into open slots on a connected Google Calendar or VantaWeb's built-in scheduling (Auto-Booking add-on, Surge and Apex), or recorded for your office to confirm. A call you class as urgent is handed to the emergency contact by cold transfer; with no answer she takes a name, call-back number and message. Her script is written not to give legal advice, and she has no access to your matters. Caller texts are off until the account enables them, which many firms will leave off. Prices: pricing page.
Where VantaWeb is not the right pick
| If this is you | Why VantaWeb fits poorly | Look at |
|---|---|---|
| You want intake written into Clio, MyCase or another case-management tool | VantaWeb has no connection to case-management software; your office enters the matter from the emailed summary | Smith.ai and AgentZap name Clio; Upfirst describes custom actions (verify each) |
| You want the conflict check run for you | Anna records the other party's name; she does not check conflicts | Smith.ai (add-on), AgentZap (against your client database), Upfirst (collects names): verify the process |
| You want live receptionists trained on legal intake | VantaWeb is AI only | Ruby, or Smith.ai's human-first plans |
| You want callers to pay a consultation fee on the call | VantaWeb does not take payments | Upfirst texts a payment link; Smith.ai and Ruby list payment options (verify) |
| You need Spanish or other languages spoken on the phone | Spanish on calls only where the account has automatic English/Spanish switching turned on (the call follows a caller who changes language; English and Spanish only) | Upfirst lists 30+ languages; Smith.ai English and Spanish; Ruby bilingual receptionists |
Questions to ask any law-firm vendor
1. Where are recordings and summaries kept, and for how long?
Ask for the processor list, the retention period and who at the vendor can read a call. Link the answer to your Rule 1.6(c) analysis.
2. Will it ever give advice?
Ask for a call that says "can I sue?" and listen for the reply. The right answer is a polite refusal and a move to intake.
3. What does the conflict process actually do?
Collecting a name, running a check against your database and flagging a hit are three different things.
4. What does the bill look like at your call volume?
Minutes, calls and live-agent add-ons differ. Price a normal week and a week after a big ad push.
Frequently asked questions
Can an AI receptionist give legal advice?
A well-written script tells it not to, and Anna's script for your firm should say so in the first sentence. Test it with a "can I sue?" call before the line goes live.
Does VantaWeb connect to Clio or MyCase?
No. VantaWeb has no connection to case-management software. Anna emails the intake details to your office, which enters the matter.
Does Anna check conflicts of interest?
No. She records the other party's name when your script asks for it, and your firm runs the check.
Test the no-advice script before it answers a caller.
We settle your intake questions, disclaimer wording, calendar and transfer number, then repeat test calls with your attorneys listening.
