Synthflow AI

What it does

Synthflow lets non-technical teams build AI phone agents through a visual, drag-and-drop interface rather than code — useful for businesses that want a voice agent handling bookings, FAQs, or lead qualification without hiring a developer. Subscription tiers run Starter ($29/month, 50 minutes), Pro ($99/month, 200 minutes), Growth ($449/month, 1,000 minutes), and Agency ($899/month, 2,000 minutes), but the platform requires bringing your own keys (BYOK) for the LLM and voice providers, which typically adds $0.02–$0.05/minute or more on top.
