What is Jotsu?
Understand how Jotsu turns a natural-language description into a working data application with managed development and deployment tools.
Jotsu builds data applications from a description of the result you need. A Jotsu application can collect, store, transform, and present data for a real workflow.
Describe an inventory tracker, approval queue, customer portal, or another data-centered tool. Jotsu creates the application and gives you a Builder where Codex can inspect and change its code.
Each application has its own interface, database, server logic, development preview, and deployment. It can also use AI, external APIs, and MCP tools when the workflow needs them.
Start with Build your first application.
