What each Human Add AI plan actually includes
Pricing is set up to be predictable, which matters for service operators who hate variable-rate billing on a critical line. The Starter tier sits at $497 monthly and is built around the 100-to-250-calls-per-month operator: a single location, a single booking calendar, and the core AI conversation engine running the intake flow. Everything in Starter is configured during onboarding and tuned by a real human on the Human Add AI side before the agent ever picks up a live call.
Professional at $997 monthly is the tier most established businesses settle into. The volume allowance jumps to 750 answered calls, multi-location routing rules unlock so a single AI receptionist can route calls to the right office, and the integration footprint expands to include the deeper CRM hooks (Salesforce, HubSpot, Pipedrive, Clio Manage, Lawmatics, Dentrix Ascend, Open Dental, Jobber, Housecall Pro, ServiceTitan, FieldEdge, and twenty more). After-hours escalation rules are also standard at this tier.
Enterprise at $1,997 monthly is the high-volume tier with unlimited inbound calls, white-label phone numbers, a dedicated agent-tuning contact at Human Add AI, and direct routing to an on-call dispatcher with priority paths for emergency calls. Outbound calling is also enabled at this tier, billed at fourteen cents per outbound minute against a transparent monthly meter that any operator can cap from the dashboard.
None of the plans use seat counts, per-minute inbound charges, transcript fees, or annual commitments. The whole pricing structure is designed so the operator can predict the bill exactly, and the upgrade path is volume-driven rather than feature-gated. A business graduating from Starter to Professional pays more because they are taking more calls, not because they got locked out of something useful.
From signup to first answered call (48 hours, three steps)
Human Add AI launches in three discrete steps that almost always fit inside two business days. Step one is the onboarding form. It collects business basics, service-area details, hours of operation, the intake questions a senior receptionist would ask on a typical inbound call (these become the agent script), the booking calendar URL, and the SMS-alert distribution list. The form is structured so the answers map one-to-one to the agent build that happens next; no extra back-and-forth is needed in most cases.
Step two is the build, which Human Add AI does inside 24 hours of the intake form being submitted. A real human reads the onboarding answers, writes the custom AI receptionist script, runs three test calls through the demo line to validate the agent handles the easy path and the harder branches correctly, tunes the voice to match the requested tone, and sends recorded samples to the operator. The operator listens to the samples, flags anything that needs adjusting, and approves the build.
Step three is the forwarding flip. Human Add AI provides a new phone number and carrier-specific instructions; the help center has button-by-button guides for every major US carrier (Verizon, AT and T, T-Mobile, Spectrum, Comcast Business, RingCentral, OpenPhone, Grasshopper, Vonage, 8x8, Dialpad, and Google Voice) plus the most common virtual carriers. Forwarding usually takes under five minutes and is fully reversible. The moment the forward is active, every call is answered in two rings by the custom AI receptionist.
The first week after launch is when the tuning compounds. The Human Add AI team monitors a random sample of real calls every morning, flags any awkward phrasing or wrong scheduling decisions, and tunes the agent in place. By Friday of week one, the agent sounds like a senior in-house receptionist, the dashboard shows the bookings and SMS lead alerts, and the operator can already see the recovered-revenue numbers from the calls that would have gone to voicemail under the old setup.
The questions worth asking before you switch
Can the agent handle a caller who interrupts or changes their mind mid-call?
Yes. The conversation engine is built around real conversational patterns, not menu trees. If a caller interrupts mid-sentence, the agent stops, listens, and responds to the interruption. If a caller changes their mind about the service halfway through (a common pattern when callers are still figuring out what they need), the agent rolls with the change and restarts the intake from the new point. Most generic AI receptionists fail on these two patterns, which is why the demo line at (617) 812-5251 is the recommended evaluation method.
What does the operator-facing dashboard look like on mobile?
The dashboard is a PWA (progressive web app), which means it installs on iPhone or Android home screen and runs full-screen without the browser chrome. The mobile view surfaces the call list, the booking calendar, the SMS lead alerts, the recovered-revenue math, and the agent knowledge base for in-the-field edits. Most operators run the platform from their phone after the first week of launch.
How does pricing compare to a part-time in-house receptionist?
A part-time in-house receptionist covering business hours only typically costs $2,400 to $4,200 per month all-in (hourly wage plus benefits plus equipment plus management time). Human Add AI Professional at $997 monthly covers the same hours plus the entire 5pm-to-9am gap plus weekends plus holidays. The operator gets fuller coverage at lower total cost, with the trade-off being that the answering is done by AI rather than a human. The right operator profile depends on the vertical and the brand voice expectations.
Does the AI accept payments over the phone?
Payment processing is available on the Professional and Enterprise tiers via Stripe integration. The agent collects the payment securely (PCI-compliant capture, no card numbers stored in plain text), processes the charge, and confirms the receipt by SMS. Most service operators use this for deposit collection on bookings, post-service balance collection, or estimate-acceptance fees. Standard Stripe processing fees apply on top of the monthly plan price.
What does the platform do during an internet or power outage at my office?
Nothing changes for the caller. The forwarding from your business line happens at the carrier level, which means it does not depend on your office internet or your office power. The agent runs in the cloud regardless of what is happening at your physical location. If your booking calendar is hosted on your local system (rare), the agent falls back to manual booking via SMS to your on-call dispatcher.
How does it handle robocalls and spam calls?
The platform runs a spam-detection filter on every inbound call that checks the calling number against the same spam-call databases used by major carriers. Suspected spam calls are dropped before reaching the agent, which saves both the operator's monthly call quota and the agent's processing time. Operators can adjust the aggressiveness of the spam filter from the dashboard or whitelist specific numbers that the filter mistakenly flags.
Is there an API for custom integrations?
Yes. The Human Add AI REST API covers webhook delivery for every call event (call-received, call-answered, call-completed, booking-created, lead-flagged, sentiment-detected), CRUD access to the knowledge base and intake script, calendar push for booking events, and a read-only endpoint for call recordings and transcripts. The full API documentation is available at /api-docs and access is enabled by request on the Professional and Enterprise tiers.
How do I evaluate it without committing?
The best evaluation is the public demo line at (617) 812-5251. Call from any phone and run a real scenario through the production agent. After the demo, the next step is the ten-minute onboarding form, which builds a custom test agent for the specific business. The test agent is free to run and use, and only converts to a paid plan once the operator decides to forward their real business line. The whole evaluation path takes about two business days end-to-end with no commitment.
How the platform fits into the daily operations rhythm
Once Human Add AI is live, the daily operations rhythm for a service-business owner changes in a small number of concrete ways. The phone stops being something the owner thinks about during business hours. Voicemail goes away because every call gets answered live. The booking calendar fills with new appointments without anybody manually keying them in. SMS alerts arrive on the on-call dispatcher's phone for every qualified lead, with the caller name, number, and intake summary already attached.
The weekly summary email arrives every Monday morning with the call count, the booking count, the SMS lead count, and the recovered-revenue math. Most operators stop opening the daily call list after the first month because the system has earned trust at that point and the weekly summary is enough. The dashboard remains available for the rare investigation: an operator drilling into a specific booking, a customer calling back about a previous conversation, or a tuning request to refine the agent script.
The change in the operator own time is the second-order effect that most operators report as the biggest unexpected value. Sixty to ninety minutes per day of phone qualification time gets returned to the operator, which can be spent on revenue-generating work, on team management, or on actually taking a lunch break. The dollar value of that time alone usually exceeds the platform monthly price for any owner-operator profile.
How the platform handles edge cases
Most service-business AI receptionist evaluations focus on the easy 80 percent of calls and underweight the harder 20 percent that contain the highest-value leads. The harder 20 percent includes callers who interrupt mid-sentence, callers who change their mind about the service halfway through, callers who use industry vocabulary that does not map directly to the service catalog, callers who are price-shopping multiple businesses in parallel, and callers who are in an actual emergency and need immediate routing to a human dispatcher.
Human Add AI is built specifically for those harder calls. The conversation engine handles interruptions by pausing and listening rather than continuing the previous statement. It handles mind-changes by restarting the intake from the new requested service, not by getting confused. It handles industry vocabulary by recognizing aliases (a caller asking for "AC repair" gets routed the same as a caller asking for "HVAC service"). It handles price-shoppers by quoting honestly with the operator-provided ranges and offering to book the free estimate. And it handles emergencies by detecting the emergency signal in the first ten seconds and routing the caller directly to the on-call dispatcher with a parallel SMS so the dispatcher knows the caller is incoming.
The public demo line at (617) 812-5251 is the recommended way to evaluate edge-case handling. Run a real scenario through the agent that mirrors the kind of call your business actually gets, including the tricky bits. The demo runs the production agent for a generic service business, so what you hear is what your customers would experience after launch. If the conversation passes the bar on the harder 20 percent, the platform is the right fit. If it does not, the operator has saved themselves the rest of the evaluation in 90 seconds.
Operators who have run the demo against three or four competing platforms before signing up almost always end up choosing the platform that handles the edge cases best, even if the headline pricing is a little higher. The reason is straightforward: the high-value leads are concentrated in the hard 20 percent of calls, so the platform that handles those calls well captures most of the recovered revenue.
