Synthflow AI

Synthflow AI is a no-code platform for building AI voice agents that handle phone calls for businesses. Users design conversational agents through a drag-and-drop visual builder called Flow Designer, without writing code. The platform supports multilingual voice agents that can hold natural, human-like phone conversations for tasks such as appointment booking, customer support, lead qualification, and after-hours call answering. Synthflow operates its own in-house telephony infrastructure, which the company states delivers sub-100ms latency and 99.99% uptime, and it also supports bring-your-own-carrier setups through Twilio, SIP, and PBX connections. The platform includes pre-built templates for common use cases like dental appointment booking, real estate qualification, restaurant reservations, and HVAC after-hours answering, letting teams launch an agent quickly.

The platform connects to more than 200 external tools, including CRMs such as Salesforce and HubSpot, along with Zapier for broader workflow automation, so call outcomes and contact records update automatically. Built-in testing tools, including an AI sandbox and real-time Auto-QA conversation analysis, let teams review and refine agent performance before and after launch. Synthflow's infrastructure carries SOC 2, HIPAA, PCI DSS, and GDPR compliance, making it suitable for regulated industries like healthcare and financial services. Pricing is largely pay-as-you-go, based on per-minute call costs, with a free tier for building and testing agents before going live, and a custom-priced Enterprise plan for larger deployments. Synthflow is built for small and mid-sized service businesses as well as larger call center and BPO operations.
