Legal integrations compared
For a law firm, the receptionist is only useful if intake lands in your practice management system. These are the legal tools each vendor names on its own pages:
| AI receptionist | Legal software named on its site | Plan | Cost at 150 calls |
|---|---|---|---|
| Smith.ai | Clio Grow, Clio Manage, Salesforce, HubSpot natively; homepage names Clio, Filevine, Lawmatics, MyCase, PracticePanther, Smokeball, Litify and Rocket Matter | Every plan includes native integrations (Clio, Zapier and others) | $270 |
| NextPhone | Clio, MyCase, PracticePanther, Lawmatics, Lead Docket, Filevine, SmartAdvocate, Litify, Lawcus, CosmoLex, LawPay, Smokeball | CRM updates (including Clio) from Growth, $299 | $199 (Pro) or $299 (Growth) |
| Upfirst | Books appointments into Clio Manage; Clio on its integrations page | Every plan | $119.95 |
| My AI Front Desk | Integrates with tools via Zapier and direct API connections | Business-in-a-Box | $161.50 |
| Rosie | Law Firms industry page; Zapier | Every plan | $149 |
What it costs for a law firm
Intake calls can run long. Per-call and flat pricing protect you from long intake calls; per-minute plans do not. Cheapest published plan at each volume (3-minute average):
| Software | 50 calls | 150 calls | 300 calls |
|---|---|---|---|
| Upfirst | $54.95 | $119.95 | $159.95 |
| Goodcall | $79 | $118.50 | $129 |
| Rosie | $49 | $149 | $149 |
| NextPhone | $199 | $199 | $199 |
| Smith.ai | $75 | $270 | $500 |
| My AI Front Desk | $99 | $161.50 | $274 |
If your intake calls run 10 minutes, per-call and flat plans stay the same, while My AI Front Desk at 150 calls would be $424 and Rosie $299.
Intake, conflicts and the human option
AI receptionists can ask your intake questions and log the answers. Smith.ai also runs human receptionists that do legal-specific work, priced per call on its Virtual Receptionists plans ($300 for 30 calls):
| Smith.ai human receptionist task | Price |
|---|---|
| New client intake (5 short-answer questions) | Included |
| Conflict checks | $0.50 per call |
| Extended intake (six more questions) | $1.50 per call |
| Accept payments | $1.00 per call |
| Book appointments | $1.50 per call |
| Third-party intake | $1.00 per call |
A common setup is AI for after-hours and overflow, with human or attorney follow-up for qualified leads. Smith.ai's AI receptionist can escalate to its human Live Agent Network (homepage: "Human escalation ($3 extra)"), and NextPhone says callers who want a human are transferred immediately.
AI or live legal answering at your volume
Many firms weigh an AI receptionist against a live answering service. At the same call counts (3-minute calls), using each option's cheapest published plan:
| Option | 30 calls (90 min) | 90 calls (270 min) | 300 calls (900 min) |
|---|---|---|---|
| Upfirst (AI, Clio booking) | $24.95 | $59.95 | $159.95 |
| Smith.ai AI Receptionist | $15 | $187.50 | $500 |
| NextPhone (AI, flat) | $199 | $199 | $199 |
| Smith.ai Virtual Receptionists (human) | $300 | $810 | $2,100 |
| PATLive (human) | $189 | $479 | $1,475 |
| Ruby (human) | $395 | $1,725 | No published plan |
Live answering is worth paying for when a single signed client is worth thousands and callers expect a person. AI is the better fit for after-hours coverage, overflow during court days, and screening calls you would decline anyway.
Ethics: what the ABA says about AI tools
The ABA's first formal guidance on generative AI, Formal Opinion 512 (July 29, 2024), says lawyers using these tools must "fully consider their applicable ethical obligations", including competence (understanding the tool's benefits and risks), confidentiality of client information, communication with clients, and reasonable fees. For a phone receptionist that means:
- Confidentiality: know where recordings and transcripts are stored, who can access them, and whether the vendor uses them for anything else.
- No legal advice: instruct the AI to take information and schedule consultations, never to assess a caller's case.
- Supervision: review transcripts regularly, as you would a new staff member's work.
- State rules: your state bar may have its own guidance; check it before launch.
Recording consent
Most of the products we compared record calls by default: Goodcall, Smith.ai and Dialzara each say every call is recorded and transcribed, and My AI Front Desk says every call is "recorded, transcribed, and summarized". Recording a phone call is governed by federal and state law, and the rules differ by state.
One-party consent (federal rule)
Federal law allows a recording when the person recording is a party to the call or "one of the parties to the communication has given prior consent" (18 U.S.C. 2511(2)(d)).
All-party consent (some states)
Some states require everyone on the call to agree. Florida allows interception only "when all of the parties to the communication have given prior consent" (Fla. Stat. 934.03(2)(d)), and Washington requires "the consent of all the participants" (RCW 9.73.030).
The practical step is the same everywhere: have the greeting say the call is answered by an AI assistant and may be recorded. Products such as Rosie and Dialzara list a custom greeting or custom AI voice; ask your vendor how to add the notice. This is general information, not legal advice; check your own state's statute if your callers are in an all-party state.
Setting it up for a law firm
- List your practice areas and the matters you do not take, so the AI can politely decline or refer.
- Write intake questions per practice area (incident date, opposing party, deadlines).
- Connect your practice management system or route intake by email to the right person.
- Set urgent rules: arrests, court dates this week and existing clients in crisis go to a person.
- Announce the AI and the recording, and avoid collecting more than you need on the first call.
- Review the first two weeks of transcripts and refine.
Frequently asked questions
What is the best AI receptionist for law firms?
On published integrations, Smith.ai (Clio, Filevine, MyCase, Smokeball and others, with human escalation), NextPhone (12 legal integrations, CRM updates from its $299 Growth plan) and Upfirst (books into Clio Manage from $24.95) are the strongest fits.
How much does an AI receptionist cost for a law firm?
At 150 calls a month: Upfirst $119.95, NextPhone $199 (Pro) or $299 (Growth with CRM updates), and Smith.ai $270. Per-call and flat plans do not rise with long intake calls.
Does an AI receptionist integrate with Clio?
Yes, several do. Smith.ai integrates natively with Clio Grow and Clio Manage on every plan, Upfirst books into Clio Manage, and NextPhone lists Clio among its 12 legal integrations (CRM updates from Growth).
Is it ethical for a law firm to use an AI receptionist?
The ABA's Formal Opinion 512 (July 2024) does not prohibit AI tools but says lawyers must consider competence, confidentiality, client communication and fees. Keep the AI to intake and scheduling, protect transcripts, and review its work.
Can an AI receptionist run conflict checks?
Not on its own in any plan we read. Smith.ai's human receptionists offer conflict checks at $0.50 per call; otherwise the AI collects names and your staff runs the check.
What should an AI receptionist never do for a law firm?
Give legal advice, assess the merits of a case, promise representation or quote outcomes. Instruct it to collect facts, book consultations and route urgent matters to a person.
Do I have to tell callers they are speaking to an AI?
Telling them is good practice and helps with recording consent: federal law allows one-party consent, but states such as Florida and Washington require every party to agree to a recording. Put both in the greeting.
What is a legal answering service?
A service that answers a law firm's calls, takes intake details and books consultations. Live versions cost far more than AI: Smith.ai's human receptionists are $300 for 30 calls, while its AI receptionist is free for 25 calls and $150 for 75.
