Voice AI

Synthflow

No-code AI voice agent builder for automating inbound and outbound phone calls. Handles lead qualification, appointment booking, and customer support without a human on the line.

What it does

Synthflow lets you build AI phone agents through a visual, no-code interface. The agent handles real-time voice conversations — it can ask questions, follow a script, respond to unexpected inputs, and take actions like booking calendar slots or updating CRM records. You define the agent's persona, give it a knowledge base, connect it to your tools via integrations, and deploy it to a phone number. The platform supports both inbound agents (answering calls) and outbound agents (initiating call campaigns). For businesses running repetitive phone-based workflows, Synthflow removes the need for human involvement in the first stages of a call.
