Synthflow AI is a no-code platform for building conversational AI phone agents that manage inbound and outbound calls. Agents are powered by leading LLMs (including GPT-4o) and can book appointments, detect voicemails, route calls via AI IVR, and handle multi-language conversations. The platform is voice-only and does not natively support other channels.
