# Synthflow

Synthflow lets businesses build human-sounding AI phone agents without writing code, using a visual builder to design conversation flows that book appointments, qualify leads, answer FAQs, and route or escalate calls. Agents speak naturally in real time with low latency, handle interruptions, and can be pointed at a knowledge base so they answer from a company's own information. The platform connects to calendars, CRMs, and hundreds of other apps through native integrations and webhooks, so a completed call can create records, trigger follow-ups, or hand off to a human. Synthflow supports both inbound and outbound campaigns, multiple languages, white-label deployment for agencies, and an API for embedding voice agents into existing products. It is aimed at sales, support, and operations teams — and the agencies serving them — that want to automate high call volumes while keeping conversations on-brand and reliable.
