Framework All Voiceflow agents are built on our framework. The framework reflects everything Voiceflow has learned about building effective AI agents. Open the Framework tab in the sidebar to see how conversations flow through your agent. The framework visualizes the path from conversation start to end, including initialization, the agent itself, and post-conversation evaluations. This gives you a quick overview of your project’s architecture without diving into individual playbooks or workflows.

​
How the framework works

Every conversation follows the same structure. It begins at the Start chip, runs an optional initialization workflow, then hands control to the Agent. The agent orchestrates your playbooks, workflows, and knowledge base via skills to handle the conversation. When the conversation ends, any enabled evaluations run automatically.

​
Choosing a framework

Click the Framework dropdown in the top left to switch between frameworks.
  • Agentic is the recommended framework for most projects. It gives your agent full access to playbooks, workflows, and your knowledge base, letting it decide how to handle each conversation.
  • Conversation flow is a simpler framework designed for legacy conversational design patterns. The Agent tab won’t be available, but you can still use playbooks within workflows via the Playbook step. Choose this if you need precise control over conversation paths or are migrating an older project.
Beyond choosing between the two framework types, it isn’t customizable.
