Quick answer: Trillet is one of several mid-tier general-purpose AI receptionists. It is fine for basic intake but is not vertical-specialized and does not include outbound or deep CRM integration. Human Add AI is the better fit for service businesses (HVAC, plumbing, dental, legal, restaurants, contractors, real estate) that want vertical-tuned AI, flat monthly pricing, 48-hour deployment, and outbound bots all included.

The honest pricing breakdown for operators
Human Add AI charges $497, $997, or $1,997 per month depending on the volume tier, with outbound calling metered at fourteen cents per minute on top of the Professional and Enterprise plans. There is no setup fee, no annual contract, no per-seat charge, no per-lead charge, and no per-call charge on inbound. The platform is intentionally priced to be a flat monthly line item that an operator can compare directly against the cost of a virtual receptionist service or the salary of a part-time in-house front desk.
The Starter tier is the right entry point for most operators. It covers a single location, up to 250 inbound calls per month, and the full conversation engine. The 250-call cap maps to a typical service business doing roughly 50 to 60 inbound calls per week. Operators expecting much higher volume should price the Professional tier, which raises the cap to 750 inbound calls per month and unlocks the multi-location routing and the CRM-deep-integration matrix.
Professional at $997 monthly is also the tier where after-hours emergency escalation routing becomes standard, where the CRM integration set covers Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, Salesforce, HubSpot, Pipedrive, Clio Manage, Lawmatics, MyCase, PracticePanther, Dentrix Ascend, Open Dental, Eaglesoft, Curve Dental, ServiceM8, RazorSync, and twenty other vertical-specific systems, and where the SLA-backed response time on agent tuning tightens.
Enterprise at $1,997 monthly is for operators who want the volume cap removed entirely, the dedicated agent-tuning contact, the white-label phone numbers, the on-call dispatcher priority routing, and the outbound module. The outbound module unlocks four use cases at the same fourteen-cents-per-minute rate: missed-call callback (the highest-ROI use), appointment reminders (24 hours before the booked time), post-service review collection, and lead nurture for prospects who asked for information but did not book on the first call.
What the operator actually does to launch
The operator-side work for launching Human Add AI takes about thirty minutes spread across two business days. Day one, the operator fills out the onboarding form, which captures business hours, service area, the vertical-specific intake questions a real receptionist would ask, the booking calendar URL, the people who should get SMS alerts, and the on-call dispatcher rotation if applicable. The form is structured so the answers map directly to the agent script that gets built next.
Between day one and day two, the Human Add AI team does the heavy lifting. They convert the intake answers into a custom AI receptionist script, run the script through three test conversations on the demo line to validate the agent handles real-world flow correctly, tune the voice to match the requested tone (warm, professional, or efficient), and send the operator three recorded sample calls to listen to. The operator listens to the samples, requests any adjustments, and approves the build.
Day two, the operator does the forwarding step. The help center provides carrier-specific instructions for Verizon, AT and T, T-Mobile, Spectrum, Comcast, RingCentral, OpenPhone, Grasshopper, Vonage, 8x8, and Dialpad. Forwarding is a five-minute task on most carriers, and the help center includes screenshots for each step. Once the forward is active, the AI receptionist is live and answering every incoming call in two rings.
Week one post-launch is the tuning week. The Human Add AI team monitors a random sample of real calls each morning, listens for any awkward phrasing or wrong-routing decisions, and adjusts the agent in place. By the end of week one, the agent is dialed in and the operator stops needing to think about the phone at all. The dashboard shows recovered-revenue numbers, booking conversion rates, and the SMS log so the operator can see exactly what the platform is doing.
Frequently asked questions
How fast does the AI answer the phone?
Every inbound call is answered inside two rings. The agent picks up before voicemail ever triggers, which means a service business never loses a lead to "they did not pick up, so I called the next listing." The two-ring pickup is hard-coded into the platform and is the same on Starter, Professional, and Enterprise plans.
What happens if the AI cannot answer a question?
The agent is built with explicit fallback rules. If a caller asks something outside the trained scope (a complicated insurance question, an unusual scheduling request, a pricing question for a service the business does not offer), the agent says so plainly and offers to text a member of the team with the caller's number. The text arrives on the on-call phone within seconds, with the caller's name, number, and a summary of what they wanted.
Can the AI book appointments directly on my calendar?
Yes. The agent reads the live availability on your Cal.com, Google Calendar, Calendly, Acuity, Jobber, Housecall Pro, ServiceTitan, or other booking system and offers the caller real slots. When the caller accepts a slot, the agent confirms the address or the service location, sends a confirmation text to the caller, drops the appointment onto your calendar with all the intake details in the notes field, and texts you the booking summary.
Does the AI work after hours and on weekends?
Yes. Human Add AI runs 24/7/365 by default. The agent answers every call regardless of time, qualifies the lead with the same questions a daytime receptionist would ask, and either books an appointment on the next available business-day slot or texts your on-call dispatcher if the call qualifies as an emergency. Roughly 35 percent of service-business calls happen outside Monday-to-Friday 9-to-5, and most of those are still booking-quality leads.
What CRMs and booking systems does it integrate with?
The platform integrates natively with Jobber, Housecall Pro, ServiceTitan, FieldEdge, mHelpDesk, Workiz, RazorSync, Cal.com, Google Calendar, Calendly, Acuity Scheduling, HubSpot, Salesforce, Pipedrive, Zoho CRM, Clio, Lawmatics, Lawyaw, MyCase, Practice Panther, Dentrix, Open Dental, Eaglesoft, Curve Dental, ServiceM8, and twenty other vertical-specific systems. If your CRM is not on that list, the team will build a Zapier or webhook handoff during onboarding.
Is Human Add AI HIPAA compliant for medical and dental practices?
Yes. Human Add AI signs a Business Associate Agreement on the Enterprise plan and routes all medical and dental conversations through a HIPAA-compliant pipeline with encryption in transit, encryption at rest, audit logging, and seven-year retention controls. The standard intake questions for medical and dental practices avoid collecting protected health information on the phone and route triage decisions to the on-call clinician.
What happens if I want to cancel?
Plans are month-to-month with no contract. Cancel anytime through the dashboard or by emailing info@humanaddai.com. Your forwarding number stays active through the end of the billing cycle, the dashboard exports every call recording and transcript as CSV plus MP3, and there is no off-boarding fee. Most operators do not cancel because the platform pays for itself in recovered missed-call revenue, but the option is always one click away.
How is this different from a virtual receptionist service?
Human virtual receptionist services like Smith.ai and Ruby Receptionists charge per minute or per call, which means costs scale with success. A busy week can cost more than the entire Human Add AI monthly plan. Human virtual receptionists also have a small staff pool, so callers reach a different person every time, and the receptionist does not know your vertical. The Human Add AI agent is custom-built for your business, costs the same flat price no matter how many calls come in, and answers every call the same way with the same accuracy.
