Trillet and Smith.ai both offer AI call answering, but they meter usage differently and solve different staffing needs. Trillet's D2C AI Receptionist is $49/month for 150 inbound AI minutes, then $0.20/minute. Smith.ai's AI Receptionist has a genuine Free tier with 25 real calls and a Pro tier from $150 for 75 calls; it can also involve North America-based human agents when configured. Smith.ai separately sells human-first Virtual Receptionist plans from $300/month. Prices were checked on 23 September 2026.
How Trillet Works: Three Steps That Secure Jobs (Not Just Messages)
Trillet can answer routine inbound questions, ask approved intake questions and book when a supported calendar is connected. A configured SMS follow-up can help after a call, but outgoing messages are billed separately and require consent. These are tools for reducing missed opportunities, not a guarantee that every caller is reached or that a job is closed without staff.
1. Vet Every Caller
Trillet can apply configured spam handling and lead-intent questions. Smith.ai also publishes spam filtering: known spam numbers can be blocked before the AI answers, and its pricing page explains how some answered spam calls may be removed from a bill. Neither service perfectly classifies every caller. Review false positives and keep a route for legitimate calls.
2. Automate Intake
For a non-regulated home-service call, Trillet can ask about the address, service needed and preferred appointment window, then email a summary. Smith.ai's AI Receptionist also advertises qualification, routing, recording, transcription, summaries and AI scheduling. Do not position Smith.ai as merely collecting a name and number. Business staff still prepare any actual quote, confirm availability and handle unusual issues.
3. Handle Follow-Ups
Trillet D2C can send configured, consented SMS follow-ups; those texts are separately billed, not unlimited free messages. Smith.ai offers notifications and custom workflows, so ask how the desired follow-up is implemented and billed rather than assuming it has no post-call options. Neither product guarantees a response or a booked job from a text.
What Happens When a Customer Says “I'll Think About It”?
A useful comparison asks four questions: Did the AI capture the right details? Can it book an available slot? How does the owner learn what happened? Who follows up after the call? Trillet can send an emailed summary and, if configured, a consented SMS follow-up. Smith.ai can qualify and summarize; its human-agent network may be configured for a complex call, with the selected involvement and pricing confirmed in the buyer's plan. For either service, the business owns its quoted price and sales decision.
Quick Comparison Table
| Buyer question | Trillet D2C | Smith.ai AI Receptionist |
|---|---|---|
| Entry option | $49/month, 150 AI minutes | Free: 25 real calls, then $3/call |
| Paid AI entry | Same $49 plan; $0.20/additional minute | Pro from $150/month for 75 real calls; more call tiers available |
| Human staff | No included human receptionist network | Configurable escalation to North America-based live agents; check trigger and any add-on fee |
| Scheduling | Native supported Cal.com, Google Calendar and GoHighLevel Calendar | AI scheduling is listed on current Free and paid plans |
| Summaries and intake | Emailed call summaries and configured intake | Recordings, transcripts, summaries, lead qualification and routing listed |
| Spam | Configured handling; test it | Vendor documents blocking and selected-call adjustments |
| Follow-up text | Configurable; outgoing SMS separately billed | Confirm exact workflow and fee with Smith.ai |
| Billing unit | AI conversation minute | Eligible real call |
At low call counts, Smith.ai's Free plan can cost less than Trillet. At longer calls, per-call billing can also compare well. The best fit depends on the real call mix, not a universal “winner” badge.
Native AI vs. AI-Plus-Human Hybrid
The Hybrid Model (Smith.ai)
Smith.ai has its own AI receptionist plus an optional live-agent network. Its public materials describe AI-initiated escalation with no extra fee and separately charge certain customer-configured human tasks; the applicable trigger and rate should be confirmed with Smith.ai. This is a genuine option when a business wants a person to take some calls. It is not correct to say every Smith.ai call automatically includes a human or that all call-handling delays are known.
The Native AI Model (Trillet)
Trillet operates a first-party application and orchestration layer while using contracted telephony, speech, model and infrastructure suppliers. The $49 D2C plan is AI-first and does not include a human receptionist. Configure transfers and fallbacks where available and test them. Do not infer universal 400-millisecond responses, zero hold time or unlimited successful call capture from the architecture.
Pricing: Per-Call (Smith.ai) vs Per-Minute (Trillet)
The Per-Call Model (Smith.ai)
Smith.ai's current AI pricing lists Free at $0 for 25 real calls, then $3 per extra call; Pro starts at $150 for 75 real calls and publishes 150- and 300-call choices; Enterprise starts at $500 for 300 calls. Its human-first receptionist pricing starts at $300 for 30 calls. AI scheduling, English/Spanish handling and standard call summaries are not paid add-ons by default on its current AI page. Optional human involvement has different triggers and fee rules; request a quote for the desired workflow.
The Per-Minute Model (Trillet)
Trillet's published D2C plan is $49 for 150 AI minutes, then $0.20 for each additional minute without a forced plan change. It has a 28-day money-back guarantee, not a free trial, and no Trillet setup fee or long-term contract. The guarantee covers the plan under the applicable terms; do not assume it refunds separately billed SMS, usage, telephony or carrier charges. Cancel at least 24 hours before renewal if you do not want another cycle.
Real-World Cost Scenarios
These plan-and-voice examples assume calls average exactly two minutes, exclude ancillary charges and use Smith.ai's published call tiers. Neither is a prediction for your business.
| Monthly calls / minutes | Trillet | Smith.ai AI pricing example |
|---|---|---|
| 20 calls / 40 minutes | $49 | $0 on Free, within 25 calls |
| 50 calls / 100 minutes | $49 | $75 on Free: 25 excess × $3; compare Pro if features differ |
| 100 calls / 200 minutes | $59 | $150 Pro/75 + 25 × $2.50 = $212.50; compare 150-call Pro tier |
| 150 calls / 300 minutes | $79 | 150-call Pro tier is approximately $270 from Smith.ai's published $1.80/included-call rate; verify checkout |
At 100 calls, the $212.50 entry-Pro calculation is below the approximately $270 150-call tier; at 150 calls, the larger tier is cheaper than paying 75 entry-Pro overages. The $270 figure is inferred from Smith.ai's published $1.80 per included call and should be confirmed at checkout. A two-minute assumption favors Trillet more than a six-minute assumption would. This is why “$150 covers 75 to 300 calls” and fixed annual savings claims are misleading.
Feature Breakdown
Call Handling and Qualification
Both services can capture approved details and route a call. Smith.ai has a human escalation path; Trillet D2C does not. Trillet can answer based on owner-reviewed business information and book within connected calendar rules. If a caller asks for advice outside the configured scope, transfer or collect a message for qualified staff rather than guessing.
Spam Protection
Both advertise or support spam controls. Smith.ai says known spam callers can be filtered before answering and describes a selected spam-call billing adjustment. Trillet's configured screening can reduce unwanted notifications, but neither provider guarantees zero spam or zero false positives.
Booking and Scheduling
Smith.ai lists AI scheduling on Free and Pro. Trillet natively supports Cal.com (including an Outlook path), Google Calendar and GoHighLevel Calendar. Other D2C CRM connections are possible via API on a self-serve basis, not a managed connector catalog. Test calendar permission, booking limits and the fallback if no slot is available.
Automated Follow-Up
Trillet can configure a consented SMS follow-up; outgoing texts cost extra. Smith.ai may support the desired handoff or post-call workflow through its own features and integrations; confirm the exact behavior rather than publishing a blanket “none.” Neither product makes a quote or pursues a lead indefinitely without configuration and oversight.
When Smith.ai Is the Better Choice
Smith.ai may fit when you want live human backup, its Free 25-call plan suits the volume, or your calls are long enough that per-call economics are better. Complex or emotionally sensitive inquiries may benefit from a trained human. A human receptionist is still not a substitute for clinical or legal professionals; confirm the agreed role, escalation protocol and restricted-data terms.
When Trillet Is the Logical Choice
Trillet may fit a small service business that needs straightforward inbound coverage, supported direct calendar booking, approved intake and a published per-minute overage. Drafting an initial agent from a website can take about five minutes, but production setup also requires review and forwarding tests. It is not an autonomous dispatch, legal intake or clinical triage service on the $49 plan.

Frequently Asked Questions
Why is Trillet cheaper than Smith.ai's paid AI plan?
Trillet has a lower paid entry price, $49 versus Smith.ai Pro from $150, but Smith.ai also offers Free for 25 real calls. The billing units differ. A proper comparison uses actual call count, length and features.
Does Trillet sound robotic?
The AI offers natural voice options and uses your reviewed business details. Sample your real call types, accents and noise conditions. No vendor can promise every response will sound or be correct like a person.
Does Trillet block spam calls?
It can apply configured screening, but not perfectly. Smith.ai also publishes spam controls, so this is not an exclusive Trillet feature.
Are follow-ups really included in the plan?
The capability to configure SMS follow-up is available on D2C, but outgoing SMS is separately billed and requires appropriate consent. Do not assume an automatic day-two campaign.
Is Smith.ai better for law firms?
A firm wanting a human escalation path may prefer Smith.ai. For Trillet, a $49 D2C workflow may handle only genuinely non-restricted routine information; sensitive legal data and any other restricted information require the appropriate safeguards and contractual scope. Neither receptionist replaces an attorney.
What is the downside of per-call pricing?
Many brief eligible calls can use a per-call allowance quickly. The upside is that a long eligible call counts once. Compare both call count and minutes.
Which is better for small businesses: Trillet or Smith.ai?
Trillet suits businesses prioritizing a $49 minute-based paid plan and supported direct booking. Smith.ai may suit low call volume on Free or a need for configured human assistance. Neither is universally better.
Can Trillet replace Smith.ai for law firms?
It may cover basic non-restricted scheduling and public-information questions, but the D2C plan should not be positioned as a replacement for confidential legal intake or human judgment. Scope any regulated or sensitive workflow separately.
What's the biggest difference between Trillet and Smith.ai?
Trillet D2C is a $49 AI-minute plan without an included human network. Smith.ai prices AI by call, starts with a Free tier and can involve live agents when configured.
What happens if Trillet encounters a question it can't answer?
Configure it to collect contact details or transfer according to your fallback rules, where available. Review summaries and keep qualified staff responsible for advice and urgent decisions; do not promise immediate escalation in every case.
The Bottom Line
Smith.ai's AI Receptionist is not merely a costly human plan: its Free tier, AI scheduling, spam controls and optional live-agent network are real strengths. Trillet's D2C paid plan offers $49/150-minute pricing, supported calendar booking and configurable follow-up, with SMS billed separately. Compare a representative month's calls and test the handoff each business needs.
Trillet D2C does not authorize HIPAA-covered patient PHI. A Trillet HIPAA workflow requires eligible Agency or Enterprise terms, an executed BAA and an applicable Order Form identifying the covered use. See Trillet healthcare. Ask Smith.ai for its own applicable BAA and workflow scope before processing PHI.
