Tools let Tambo go beyond generating UI -- they allow the AI to call your JavaScript functions to fetch live data, write to databases, trigger workflows, or perform any other action your app supports. You define a function with a Zod schema for its parameters, register it with Tambo, and the AI decides when to call it based on the conversation.
