Multilingual Capabilities

Synthflow offers support for 90+ languages, enabling businesses to connect with global audiences seamlessly. Retell AI only supports 50+ languages, limiting its reach for multilingual operations.

Workflow Customization

Synthflow features a no-code drag-and-drop interface, giving businesses full control to customize workflows quickly and easily. Retell AI relies on pre-built templates, which restrict flexibility and adaptation.

Low Latency

Synthflow ensures latency under 500ms for smoother and faster interactions, while Retell AI’s latency ranges from 700ms to 1500ms, potentially causing delays in customer engagement.

Advanced Integrations

Synthflow integrates seamlessly with CRM platforms like HubSpot, Zoho, and GoHighLevel, along with SIP trunking for any telephony provider. Retell AI is limited in its telephony options, restricting compatibility.

Dedicated Support

Synthflow provides 24/7 support and a dedicated success manager for every client. Retell AI lacks 24/7 support, which may lead to delays in resolving
critical issues.

PRICING
