About Zatanna
Zatanna is building the infrastructure for AI to interact with software. AI agents are increasingly capable of performing work that was previously done by humans, but they're still constrained by software interfaces designed for people. Today, agents rely heavily on clicking buttons, navigating pages, and interacting with UIs to get things done. At Zatanna, we're changing that by reverse engineering applications to turn their underlying workflows and actions into reliable, read-and-write APIs, regardless of whether those applications offer APIs themselves.
