Hear What Our Users are Saying
We handle everything behind the scenes so your AI sounds natural and creates necessary actions in tech stack

After trying several AI voice platforms, Synthflow is the one that truly stands out. The overall platform just works—it’s intuitive, reliable, and easy to navigate. What really impressed us was how quickly we were able to get up and running. The go-to-market process is smooth and efficient, with minimal setup time, so we could start integrating the AI voices into our projects almost immediately.
I’ve used Synthflow extensively since first engaging with voice AI tech about three months ago. I like their platform and how easy it is to set a voice agent and get it working. I was able to create an inbound agent that answers calls at a law firm, sets appointments, and live-transfers calls upon request. There is inline integration with Zapier so you can build zaps directly within the Synthflow ecosystem, which is convenient.
I’ve had a fantastic experience working with this company, especially with their AI voice services. The quality of their software is top-notch, delivering consistently reliable performance that has significantly enhanced our operations. Their team is incredibly responsive, addressing any technical challenges swiftly and effectively. The level of service and support they provide is truly exceptional, and I couldn’t be more satisfied with the results!
Hands down the best conversational AI platform on the market. Easy of use, configurability, and time to market are all big ++!
The AI Assistant has dramatically improved the way we manage schedules. We now can focus more on patient care, without admin burden.
