Smith.ai Voice Assistant vs. Synthflow: Which AI answering assistant is best for your business?

When it comes to managing your business’s calls, both Smith.ai Voice Assistant and Synthflow offer essential features like 24/7 call answering, FAQ answering, lead qualification, integrations, and call routing & transfers. But, not all AI voice assistants deliver the same level of value and reliability. Let’s break down the differences to help you find the right solution for your business.

Essentials: What both platforms provide

Smith.ai and Synthflow both offer a solid foundation for conversational AI that handles business calls effectively. The shared features include:

  • 24/7 call answering: No call goes unanswered, regardless of time or day.
  • Lead qualification: Screen callers to identify high-value leads based on your preferences.
  • Appointment scheduling: Book appointments live on the call — keeping your calendar full.
  • FAQ answering: Handle common inquiries about your business, like hours, location, and services.
  • Call transfers: Direct calls to the appropriate team members or department.

Smith.ai surpasses Synthflow

When you compare the additional benefits that Smith.ai Voice Assistant offers your business, the difference between these two AI answering services becomes crystal clear.

The Smith.ai advantage

Professional, human assistance — 24/7/365

AI is powerful, but it’s not perfect. That’s why Smith.ai combines advanced AI technology with human receptionists available 24/7. Our blended approach ensures all client interactions are handled with care and expertise. 

While Synthflow offers human transfers, they mostly rely on AI and don't have humans available at all times. Smith.ai’s human backup provides unmatched reliability for callers with sensitive or complex scenarios. When AI reaches its limits, our highly trained virtual receptionists are always available to step in and ensure your calls are handled professionally if your internal staff is unavailable. 

Without this crucial feature, Synthflow risks leaving clients dissatisfied in situations when human intervention is essential but unavailable. Our Voice Assistant is the ultimate balance between efficiency and human touch. Your clients and your reputation will thank you.

Stellar support

Synthflow’s white-glove onboarding support is only available to higher-tier clients, leaving others to navigate the platform largely on their own. Users note gaps in support that affect their experience. Smith.ai, on the other hand, offers expert support from the very beginning — regardless of your plan. Our dedicated team is always ready to guide you through setup and beyond, ensuring your experience matches the exceptional service we deliver.

Our calling cards: Longevity & expertise

Smith.ai’s 10 years of experience in the call center industry set us apart. We’ve been perfecting customer call experiences long before AI answering services became popular. In contrast, Synthflow is a newcomer, launching in 2023. This lack of tenure means Synthflow lacks the dependability and established trust that Smith.ai naturally offers. Our proven track record on Clutch and G2 is a testament to our commitment to excellence.

Exceptional quality assurance

At Smith.ai, quality assurance is more than a promise — it’s a commitment. We rigorously test and refine our AI technology to catch potential issues before they reach your customers. Real-time analytics ensure consistent improvements in AI call handling, while our highly rated human receptionists further enhance accuracy and professionalism. With a focus on precision and constant evolution, Smith.ai delivers unmatched quality that your business can count on.

Stay in the know

Business owners need to stay informed, and Smith.ai makes it easy. We provide instant call summaries via your preferred method — text, email, Slack, or Teams — so you’re always in the loop. Synthflow, on the other hand, limits notifications to text and email, offering less flexibility. With Smith.ai, you can stay connected to your business in the way that works best for you.

A starter plan with real value — and simple pricing

Smith.ai’s Voice Assistant starter plan is designed for businesses that actually want to use AI, not just dabble in it. Synthflow’s $29/month starter plan only includes 50 minutes of call time, which is barely enough to see any benefit. Don’t be fooled by the low intro pricing — jumping to their next plan costs a steep $450/month, and their per-minute pricing makes budgeting unpredictable. 

With Smith.ai, you get straightforward per-call pricing that’s easy to manage. Plus, every Voice Assistant plan includes all features with no tiered limitations. Compare that to Synthflow, where the starter plan locks away custom tools, tailored support, and onboarding unless you’re paying premium prices. 

Easy access to call recordings

Smith.ai makes it simple to access your call recordings directly from our intuitive dashboard or via Zapier, API, and CRM integrations. In contrast, Synthflow’s approach for accessing call recordings is much less flexible — users must rely on APIs or third-party integrations to retrieve their recordings, adding unnecessary complexity. With Smith.ai, you can quickly review recordings without the hassle, making it easier to stay on top of client interactions. We prioritize ease of use so you can focus on what matters most.

The verdict

If you’re looking for a solution that goes beyond the basics, Smith.ai Voice Assistant is the clear winner. From 24/7 human backup to advanced quality assurance and superior support, Smith.ai delivers the tools and expertise your business needs to excel. 

For growth-minded business owners who value reliability, quality, and a personal touch, Smith.ai is the superior choice over Synthflow for your AI call-answering needs.
