When your firm is evaluating AI receptionist options, the choice between Smith.ai and OpenPhone Sona comes down to a fundamental question: do you want a phone system with an AI layer bolted on, or a purpose-built intake operation designed to capture, qualify, and convert every call? Both promise to handle calls around the clock — but the architecture, the people behind it, and the operational depth are meaningfully different.
Smith.ai was built from the ground up as a front-office workforce, not a communication platform. That distinction matters most when a call is complex — a prospective client in distress, a time-sensitive legal matter, a caller who needs more than a message taken. Smith.ai's hybrid model pairs AI that handles scale and speed with 500+ trained, North America–based live agents who step in for the moments that require real judgment and empathy. The result is a system where no call falls through the cracks, and where the quality of every interaction reflects on your practice.
OpenPhone Sona, by contrast, originates as a business phone platform — its AI receptionist capability is an extension of that product line. For attorneys and legal teams who need consistent, qualified intake rather than just answered calls, the difference is significant. Smith.ai has handled 25M+ calls over 10+ years, building operational depth and a self-improving quality loop that a newer AI layer on a phone product structurally cannot replicate. When a lead's first impression of your firm is the voice that answers the phone, that depth is not a minor detail.
Frequently asked questions
Is Smith.ai or OpenPhone Sona better for a law firm?
Smith.ai is purpose-built for businesses that need consistent, qualified intake — making it a strong fit for law firms where every call is a potential case. Its hybrid AI and live agent model ensures complex or sensitive calls are handled with the judgment and empathy legal clients expect, not just logged as messages.
Does Smith.ai use live agents, or is it fully AI?
Smith.ai uses both. AI handles scale and speed; 500+ trained, North America–based live agents handle calls that require nuance, escalation, or live qualification. This hybrid model means callers always reach a capable voice — human or AI — matched to the complexity of their call.
How does Smith.ai's pricing compare to OpenPhone Sona?
Smith.ai uses per-call pricing, which means predictable monthly costs without per-minute overage surprises. OpenPhone Sona bills per minute, which can make costs harder to forecast — especially during high-volume periods or longer intake conversations.
Can Smith.ai integrate with legal practice management software?
Yes. Smith.ai integrates with 7,000+ tools, including leading legal CRMs like Clio, Lawmatics, Filevine, and MyCase. Intake data captured on calls can flow directly into your existing systems without manual re-entry.
What happens when a call is too complex for AI to handle?
Smith.ai's hybrid model is designed for exactly this scenario. When a call exceeds what AI should handle — a distressed caller, a nuanced legal situation, a live transfer request — a trained North America–based agent steps in seamlessly. No call is left to an AI that isn't equipped for it.
How long has Smith.ai been operating compared to OpenPhone Sona?
Smith.ai has been operating for 10+ years and has handled 25M+ calls. That operational history means the system has been refined across an enormous range of real call scenarios — a depth of learning that newer AI receptionist products are still building toward.
