Trillet and Smith.ai solve the same core problem, a missed call is a missed customer, but they take different paths. Trillet is a native AI receptionist that answers, qualifies, books, and follows up on its own. Smith.ai pairs its own AI with North America based human agents for calls that need a person. This guide lays out how each works, what each costs, and which one fits your business.
How Trillet Works: Three Steps That Secure Jobs (Not Just Messages)
Many answering services stop working the moment they hang up the phone. Trillet keeps going. Every call runs through three stages:
1. Vet Every Caller (Blocks Spam Automatically)
Before wasting your time, Trillet filters out robocalls, telemarketers, and spam using AI powered screening. A human-staffed service typically answers every call, including spam, which still generates notifications.
The difference: Trillet blocks junk before you see it, so you only get real business inquiries.
2. Automate Intake (Collects Job-Specific Details)
Unlike services that simply say "leave your name and number," Trillet completes your intake checklist during the call:
- HVAC contractors: System type, age of unit, urgency level, property details, preferred service window
- Plumbers: Issue type, property age, emergency status, photos of the problem area (via text), timeline
- Electricians: Current issue, panel type, permit requirements, property access details
- Landscapers: Property size, service needed, budget range, seasonal timeline
- Auto shops: Vehicle make, model, year, mileage, service history, symptoms
The result: When you review the lead, you have everything needed to quote or book immediately, no callback required.
What a basic message service gives you: "Sarah called about her car. Call her back."
What Trillet gives you: "Sarah's 2018 sedan (87k miles) needs brake service. Last service was 6 months ago. She's available Tuesday afternoons and her budget is $300 to $500."
3. Handle Follow-Ups (Included in the Plan)
When a caller isn't ready to commit ("I'm still browsing" or "Let me think about it"), most services end the call and hope the caller comes back. Research shows that 80% of sales require five or more follow-ups to close, yet nearly half of sales reps give up after just one attempt.
Trillet automatically sends personalized SMS follow-ups a couple of days later to keep leads warm and convert hesitant callers into booked jobs. Text message follow-ups receive a 112.6% higher conversion rate than other methods.
Example follow-ups that convert:
For HVAC contractors:
"Hi, this is Trillet for [Company]. You called about AC repair earlier this week. We have availability this Friday if you're ready to move forward. Book here: [Link], or let me know if you have questions."
For law firms:
"This is [Firm]'s assistant. I saw you called about [issue]. If this is time-sensitive, reply 'URGENT' and I'll alert the attorney immediately. Otherwise, book a consultation here: [Link]"
For plumbing services:
"Hi, this is Trillet for [Company]. You reached out about [service] on Monday. We had a cancellation open up for tomorrow afternoon if that works better for your schedule: [Link]"
This feature recovers leads that a message-only service loses.
What Happens When a Customer Says "I'll Think About It"?
This is where the two approaches produce different outcomes.
The Smith.ai Approach:
- Customer calls: "I'm interested in your plumbing services, but I need to check my budget."
- Smith.ai AI: Asks qualifying questions, captures details
- If needed, escalates to a human agent for a more complex discussion
- You receive a detailed notification: "Lead: Jane Smith, interested in plumbing, needs to check budget. Discussing with spouse."
- The ball is in your court: You manually call back, text, or email
- If she doesn't answer: You play phone tag, often for days
Result: Professional call handling with human backup, but you still do the manual follow-up work.
The Trillet Approach:
- Customer calls: "I'm interested in your plumbing services, but I need to check my budget."
- Trillet AI: "Totally understand. Just so I can give you accurate pricing, what's the issue? Is it a leak, clog, or installation?" (captures intake details)
- Trillet AI: "Got it. I'll text you a quote range in the next hour, and you can book directly if it works. Sound good?"
- A few days later (if no booking): Trillet automatically sends: "Hi Jane, this is [Your Business]. I know you were considering [service]. We have an opening Thursday at 2 PM if you're ready: [booking link]. No pressure."
Result: The lead gets proactive follow-up without you lifting a finger.
Industry data suggests 40% to 60% of "I'll think about it" leads convert when followed up within three to five days. Smith.ai captures these leads professionally, but you handle the follow-up manually. Trillet automates this, turning hesitant inquiries into booked jobs without phone tag.

Native AI vs. AI-Plus-Human Hybrid
To choose the right platform, understand how each handles a call.
The Hybrid Model (Smith.ai)
Smith.ai uses its own AI for greeting and routing, then hands off to North America based human agents for calls that need a person. That human layer is a genuine strength for sensitive or complex conversations, and Smith.ai has more than 20 years of brand trust behind it. The trade-offs are cost and the possibility of hold time when a call transfers to a person.
The Native AI Model (Trillet)
Trillet uses native AI to handle the entire journey, from spam filtering to qualification to scheduling to SMS follow-up, without a human intermediary. Responses average about 400 milliseconds (sub one second), so the conversation feels natural, and infrastructure-level concurrency means multiple calls can be answered at once without a busy line.
The advantage: Predictable per-minute pricing, instant answers, and automated follow-ups around the clock. The honest trade-off: for calls that genuinely require human empathy or legal judgment, Smith.ai's human agents are the safer choice.
Pricing: Per-Call (Smith.ai) vs Per-Minute (Trillet)
The biggest difference is how you are billed.
The Per-Call Model (Smith.ai)
Smith.ai bills per call on both its AI and human plans (current, canonical pricing):
- AI Receptionist: Free tier (25 calls, then $3.00/call), Pro $150/mo (75 to 300 calls, $1.80 to $2.00/call), Enterprise $500+ ($1.60 to $1.67/call).
- Human plans: Starter $300/mo (30 calls, $11.50/call over), Basic $810/mo, Pro $2,100/mo, Enterprise custom.
- Booking, Spanish, and payment collection are per-call add-ons.
A busy month means more calls, and more calls means a higher bill. Short and long calls both count as one call.
The Per-Minute Model (Trillet)
Trillet is $49/month for 150 included minutes, then a flat $0.20/minute with no plan change and no service interruption. There are no per-call surcharges and no minute tiers to manage. You also get a 28-day money-back guarantee, no contracts, and no setup fees. Concurrency is unlimited (you never hit a busy line), but minutes are metered, so this is transparent per-minute pricing, not an all-you-can-use flat rate.
Real-World Cost Scenarios
Actual per-call vs per-minute math depends on how long your calls run. These scenarios assume a roughly 2-minute average call.
Scenario A: Lower-Volume Solo Business (~100 calls/month, ~200 minutes)
- Trillet: $49 base + 50 overage minutes at $0.20 = $59/month
- Smith.ai AI Pro: $150/month (the Pro tier covers 75 to 300 calls)
- Approx. annual savings with Trillet: ~$1,092
Scenario B: Busy Service Business (~150 calls/month, ~300 minutes)
- Trillet: $49 base + 150 overage minutes at $0.20 = $79/month
- Smith.ai AI Pro: $150/month (still within the Pro call range)
- Approx. annual savings with Trillet: ~$852
The pattern: Trillet's entry point and per-minute economics come in well below Smith.ai's AI Pro tier at typical call lengths, and the gap is far wider against Smith.ai's human plans ($300 to $2,100/month). Where Smith.ai earns its premium is the human layer for calls that need it.
Feature Breakdown
Call Handling & Qualification
- Smith.ai: Uses AI for greeting and routing, then transfers to North America based human agents for calls that need a person. Reliable for complex calls, but a transfer can introduce hold time.
- Trillet: Conducts complete intake instantly. The AI captures job details, budget, timeline, and technical specifics in real time without transferring or putting callers on hold.
Spam Protection
- Smith.ai: Answers calls broadly, so spam and robocalls can still reach you.
- Trillet: AI powered screening blocks spam, robocalls, and telemarketers before they reach your phone. You only see legitimate business inquiries.
Why this matters: Americans receive an average of 31 spam calls per month, with 21 of those being robocalls. Filtering that noise out saves you real time.
Booking and Scheduling
- Smith.ai: Human agents can schedule appointments if you provide calendar access, subject to agent availability.
- Trillet: Books appointments in real time during the call and sends booking links via text. Native calendar sync works out of the box with Cal.com (which also covers Outlook), Google Calendar, and GoHighLevel Calendar. You can also connect your CRM or other tools through Trillet's platform API on a self-serve basis.
Automated Follow-Up
- Smith.ai: Follow-up is not a standard feature; once the call ends you typically re-engage the lead yourself.
- Trillet: Automatically re-engages hesitant leads with context-aware SMS follow-ups a couple of days later. This is included in the plan.
When Smith.ai Is the Better Choice
Native AI handles the vast majority of business calls, but Smith.ai's human agents remain the right choice for specific high-stakes situations.
Consider Smith.ai if you operate in:
- Crisis management or sensitive intake that requires human empathy and immediate judgment
- Complex legal intake that requires nuanced liability screening
- Medical triage that requires human clinical judgment
For these scenarios, Smith.ai's North America based human agents and long track record justify the higher, per-call cost.
When Trillet Is the Logical Choice
For most service businesses, Trillet covers the job at a fraction of the cost. Trillet is the stronger fit if you:
- Run a trade business: Plumbers, HVAC, electricians, landscapers, auto shops
- Want predictable bills: Transparent per-minute pricing instead of per-call surcharges
- Hate phone tag: You want the AI to complete intake and chase leads for you
- Value speed: You want instant pickup with zero hold times. Research shows engaging leads within 60 seconds of an inquiry can boost conversion rates dramatically.
- Need spam protection: You're tired of robocalls and telemarketers
- Want follow-ups handled: You don't have time to text every hesitant lead

Frequently Asked Questions
Why is Trillet cheaper than Smith.ai?
Trillet uses native AI for the entire call workflow (spam filtering, intake, follow-up), so it doesn't carry the labor cost of human agents, and it passes those savings on as transparent per-minute pricing. Smith.ai staffs North America based human agents for calls that need a person, which is a genuine strength but adds cost.
Does Trillet sound robotic?
No. Trillet uses a natural voice and handles interruptions, pauses, clarifying questions, and context shifts. The experience feels like a real receptionist: natural voice, your business details, and immediate answers. It supports 32 languages.
Does Trillet block spam calls?
Yes. Trillet uses AI powered screening to identify and block robocalls, telemarketers, and spam before they reach your phone or generate notifications. Robocalls are projected to cost billions in losses in the coming years, so filtering them out has real value.
Are follow-ups really included in the plan?
Yes. Automated SMS follow-ups are a standard feature in Trillet's $49/mo plan, not an add-on. When a caller isn't ready to book, Trillet automatically sends personalized follow-up texts a couple of days later to re-engage them.
Is Smith.ai better for law firms?
For complex legal consultations that require empathy, nuanced liability screening, or sensitive case evaluation, Smith.ai's human agents are a strong choice. For routine inquiries, appointment scheduling, and general intake, Trillet is faster and more affordable.
What is the downside of per-call pricing?
Per-call pricing can create bill surprises. A successful marketing campaign that drives more calls raises your answering-service bill. Trillet's per-minute pricing ($49 for 150 minutes, then $0.20/min) makes budgeting more predictable.
Which is better for small businesses: Trillet or Smith.ai?
For most small businesses, Trillet is the better fit thanks to a lower entry price ($49/mo) and transparent per-minute billing. Smith.ai is the better fit if you specifically need human agents for complex or high-stakes calls.
Can Trillet replace Smith.ai for law firms?
For routine legal inquiries, appointment scheduling, and general case intake, yes. For complex intake that requires liability screening, empathy for trauma cases, or immediate human judgment, Smith.ai's human agents remain a strong choice.
What's the biggest difference between Trillet and Smith.ai?
Trillet is pure native AI: it blocks spam, automates intake, and handles SMS follow-ups, all billed per minute. Smith.ai is a hybrid that adds North America based human agents for complex calls, billed per call. Trillet is faster and cheaper for routine business calls; Smith.ai is stronger for high-stakes conversations that need a person.
What happens if Trillet encounters a question it can't answer?
If the AI hits a question outside its scope, it collects the caller's information with full context and escalates to you immediately (with an SMS alert for urgent calls), so you always know what the caller wanted.
The Bottom Line
If you operate in high-liability industries that require human judgment for sensitive conversations, or you specifically value 20+ years of brand trust and North America based human agents, Smith.ai is a solid, established choice.
If you're an owner-operator who loses money to phone tag, spam calls, and manual lead chasing, Trillet fixes those problems at a lower, more predictable cost: $49/month for 150 minutes, then $0.20/minute, with a 28-day money-back guarantee.
Most services leave you with a list of people to call back. Trillet leaves you with booked appointments and filtered leads ready to close.
Updated for July 2026: corrected Trillet pricing to $49/mo (150 min, then $0.20/min) and removed the false "unlimited flat-rate" framing; corrected Smith.ai pricing to canonical numbers (AI Pro $150, Enterprise $500+, human plans $300 to $2,100); removed the unsourced "500+ agents" claim and any "callers can't tell it's AI" language; conceded Smith.ai's human-agent and brand-trust strengths; added D2C internal links.
