While traditional assistants center on a hosted prompt-and-response experience, Vellum can function as a persistent personal assistant, remember useful context across sessions, and execute background routines. Its open-source foundation, hosting choices, and security controls distinguish it from assistants that bind every task to one hosted interface. Self-hosting provides the strongest local control, while cloud hosting trades some data locality for convenience. That combination gives users a practical choice between managed operation and a more private, hands-on deployment. ## What is the difference between an AI assistant and an AI agent builder? -An AI assistant helps a person think or create through conversation, while an AI agent builder lets a team design, deploy, and manage systems that take actions across models, tools, and business applications. +An AI assistant helps a person think or create through conversation, while an AI agent builder lets a team design, deploy, and manage systems that take actions across models, tools, and business applications.

The distinction is practical: if a person must prompt the system and manually move each result into another tool, it is functioning as an assistant.
