Pricing combines editor seats with a usage-based credit system.

Voiceflow is a platform for designing, prototyping and deploying AI agents across chat and voice. It centers on a visual, collaborative canvas where teams map out conversation flows, connect LLMs, add knowledge sources and define logic, then publish to channels such as web chat, voice and messaging. Often described as a 'Figma for conversational AI,' its strength is letting product, design and engineering collaborate on the same agent. The platform supports multiple LLM models, knowledge-base grounding, API calls and analytics, making it suitable for building customer-support assistants and more complex agentic workflows. Pricing combines editor seats with a usage-based credit system: interactions consume credits based on what the agent does, whether handling a chat message, making a voice call or invoking an AI model. Voiceflow is a venture-backed company that has raised roughly $39 million across several rounds to date, including a $15 million round led by OpenView Venture Partners. It is a good fit for teams that need collaboration and design rigor around their agents, though the credit model means costs scale with usage and should be modeled carefully.
