About Voiceflow
Voiceflow doubles down on agentic primitives — Shopify tools, fail paths, skip-turn behavior.
Voiceflow is filling in the missing primitives for production conversational agents — a one-click Shopify integration that unlocks live commerce data, native failure paths on Function and API steps, a skip-turn tool for natural conversational pacing, and Flux STT now spanning 10 languages. Evaluation and analytics surfaces are getting parallel polish: preview cards, default transcript properties, workflow usage in analytics.
