Synthflow · Voice Agents & Speech/Audio

No-code AI voice agent builder with tiered subscriptions + per-minute overages. Starter $29 (50 min), Pro $99 (200 min), Growth $449 (1000 min), Agency $899 (2000 min), Enterprise custom (10K+ min). White-label option runs ~$2,000/mo. Voice engine alone ~$0.09/min; all-in $0.15–0.37/min with LLM + telephony.

In other words, Synthflow is worth it for small businesses and agencies that want no-code AI voice agents without touching a developer platform like Vapi or Retell. Starter ($29) makes prototyping cheap. Agency ($899) with white-label unlocks reselling to clients — differentiator vs. Vapi/Bland. Trade-off: less flexibility than developer-first platforms and the minute caps sting on scale (2K min = ~33 hours of talk time).
