Smith.ai vs. IsOn24: Which AI voice assistant is best for your business?

For most small to medium-sized businesses, missed calls mean missed opportunities and lost revenue. However, hiring additional staff to answer calls and schedule appointments can be costly. More companies are turning to AI-powered answering services with AI voice assistants to handle their calls, relieving their internal staff to focus on more complex tasks. Compare our AI-first answering solution, AI Receptionist, with IsOn24 to find the best solution for delivering exceptional customer experiences. 

Features that both solutions offer

  • 24/7 call answering: Stay responsive no matter the time of day.
  • Lead qualification: Identify high-value leads.
  • Appointment scheduling: Book appointments & reservations into your calendar or CRM.
  • Call routing & transfers: Send calls to the appropriate staff member.
  • Answering FAQs: Provide prompt, accurate responses to common inquiries.
  • Call recording & transcription: Stay informed with full call records.
  • Simultaneous call handling: Handle multiple calls at once.
  • Reporting & analytics: Track call performance & gain actionable insights.

What sets Smith.ai apart

Beyond these standard AI answering features, Smith.ai equips your business with always-on human support, immediate call summaries for every call, intelligent call filtering, accessible integration, and dedicated onboarding with every plan — all supported by our trusted, proven reputation.

Uninterrupted human coverage

While AI handles routine calls efficiently, some complex situations still demand a human touch. Smith.ai's hybrid approach delivers the best of both worlds: AI speed with 24/7 live virtual receptionists ready to seamlessly step in for critical conversations, even when your team can't.

IsOn24 relies solely on transferring to your internal staff for human interaction, risking delays and lost opportunities when your team is unavailable or overloaded.

Smith.ai ensures continuous, expert call handling, providing the flexibility growing businesses like yours need to capture every opportunity around the clock.

Stay in the loop on every call

Smith.ai provides instant email summaries for all calls, giving you complete visibility into every customer touchpoint. Notifications can even be customized to your preferences.

IsOn24 filters your call information, alerting you only to matters that require your action and pushing the rest to their app or your CRM. This approach risks missing valuable nuances and insights from calls that might not seem urgent but still hold important customer information you need to know.

Advanced spam blocking features

Smith.ai automatically blocks over 20 million robocalls and spam calls for free, prioritizing genuine business inquiries and managing costs. Plus, we give you granular control: block unwanted numbers, ensure VIP calls (like family) always get through, and send non-critical calls to voicemail.

IsOn24 mentions conditional call forwarding, but does not provide any public information about spam filtering or blocking features, whereas Smith.ai clearly offers advanced features designed to optimize your call handling and costs.

Integration access on every plan

Streamlined workflows are crucial for business growth, which is why we offer dozens of native integrations for simple setup, plus thousands more via Zapier and Make — accessible on every AI Receptionist plan. 

IsOn24 limits integration access, reserving this connectivity for higher-paying customers. While IsOn24 natively integrates with Jobber, their reliance on Zapier for several other connections — coupled with in-depth support only being available on higher-tier plans — creates unnecessary complexity.

With Smith.ai, you get the connections you need to thrive, without tiered limitations.

Built on a foundation of success

Smith.ai has been mastering AI-driven customer engagement in the answering service industry for a decade. This longevity and expertise translate into exceptional customer interactions that drive tangible growth, proven by our stellar ratings on Trustpilot, Clutch, and G2.

Though founded around the same time as Smith.ai, IsOn24 lacks the strong online reputation and proven experience that Smith.ai has built over the years.

The smarter choice: Smith.ai

For growing businesses that value 24/7 human support, instant summaries for every call, robust blocking controls, universally accessible integrations, and a proven track record, Smith.ai is the key to empowering your business success over IsOn24.
