What's Smith.ai?
Smith.ai is a virtual receptionist service founded in 2015. They started as a 24/7 human answering service for small businesses — particularly law firms — and have since added AI receptionist capabilities. As of their public website, pricing starts around $293/mo for 30 calls/month with overage billing. They're known for high-quality human operators, integrations with legal practice-management tools (Clio, MyCase), and a strong reputation in the legal vertical.
What's Oprantis?
Oprantis is an AI-native receptionist platform built specifically for service businesses across four verticals — trades contractors, medical practices, legal firms, and financial advisors. Founded in March 2026 by Peter Bigelow, a 25-year contractor based in Orange County, CA. Aria, the platform's AI agent, answers every inbound call within 2 seconds, runs vertical-tuned intake, and syncs to your CRM. Pricing: $197-$1,497/month flat, no per-call charges within plan minutes.
Pricing comparison
Smith.ai's published pricing (as of 2026-05-01, per smith.ai) is per-call or per-minute with monthly minimums. Their AI receptionist starts around $97-$140/mo for low-volume; their human-supported plans run $293-$700+/mo depending on call volume. Overages billed per call.
Oprantis is flat monthly: Starter $197 (300 min), Growth $497 (600 min), Concierge $1,497 (1,200 min). No per-call charges within plan limits. Most service businesses with moderate-to-high inbound volume find Oprantis cheaper at scale because the per-minute economics flatten.

Where Smith.ai wins
- Track record. Smith.ai has been operating since 2015 with thousands of customers and extensive review history on G2, Capterra, and Google Business. Oprantis is new (founded March 2026); the social-proof gap is real.
- Human voice option. If you want a human receptionist (not AI), Smith.ai is set up for that. Oprantis is AI-only.
- Legal-vertical depth. Smith.ai's integration with Clio, MyCase, and other legal practice-management tools is more mature than Oprantis's current legal stack (Oprantis writes intake to HubSpot natively; legal-specific integrations are roadmap).
- Established case studies. Smith.ai has published case studies and customer reviews. Oprantis is in the early customer cohort phase.
Where Oprantis wins
- Vertical depth across 4 industries. Smith.ai is broadest in legal but generic elsewhere. Oprantis ships vertical-tuned intake scripts for trades, medical, legal, AND financial — not a generic AI applied to any industry.
- Operator-built. Oprantis is founded by a 25-year contractor who lived the missed-call problem. The product roadmap reflects what service-business operators actually need (dispatch, recall, lead-source ROI), not what looks good in a software-founder demo.
- Flat monthly pricing. No per-call surprises. For businesses with 100+ inbound calls/month, Oprantis is meaningfully cheaper than Smith.ai's per-call billing.
- Faster setup. ~48 hours to live vs. Smith.ai's typical 5-10 business days.
- 30-day money-back guarantee. Spelled out in plain English on our /guarantee/ page. No fine print.
- Founders pricing locked. First cohort of customers locks lifetime pricing at sign-up.
Who should choose Smith.ai?
If you're a law firm that wants a human voice on every call, has legal-tech-stack integrations as a hard requirement (Clio, MyCase native), and prefers a vendor with a 10+ year track record over a newer platform — Smith.ai fits well. The premium pricing reflects premium human-operator quality.
Who should choose Oprantis?
If you're a service business in trades, medical, legal, or financial; you want vertical-tuned intake configured for your industry specifically; you want flat monthly pricing without per-call billing; you value operator-built software over software-founder polish; and you can stomach being part of a newer platform's early cohort in exchange for founders pricing and a 30-day money-back guarantee — Oprantis fits well.
Bottom line
Smith.ai is the safe, mature, human-voice-available option. Oprantis is the operator-built, vertically-tuned, flat-priced AI-native option. Both are real products with real customers. The choice usually comes down to: do you need human operators (Smith.ai) or do you trust a current-generation AI to handle 100% of intake (Oprantis)? And do you value track record (Smith.ai) or operator-fit + price (Oprantis)?
