how to use
Users can begin with Voiceflow by accessing its visual canvas to design conversational flows. The platform supports iterative development, allowing for prototyping, testing, and deployment of AI agents across various channels.
pricing
Voiceflow operates on a freemium model with tiered subscription plans and usage-based credits. The platform transitioned to a credit-based billing system on April 29, 2025, for all features, aiming for transparent pricing. Users receive 1000 free interactions per month. Beyond the free tier, usage is billed at approximately $0.002 per interaction. Additionally, Voiceflow supports various Large Language Models (LLMs) with specific per-token pricing for input and output, which varies by model. For example, input tokens for OpenAI gpt-3.5-turbo-0125 are $0.000625 per 1k tokens, and output tokens are $0.001875 per 1k tokens. Voiceflow Core is optimized for agent tasks and aims for lower per-token costs.
