Try Jev's structured AI decisions in hands-on examples
What does Jev AI Tools do?
Jev AI Tools is an independent playground for TypeSafe AI's Jev evaluation model. Developers can try a customer-message example and six interactive experiments, then inspect how structured answers feed application rules. Jev can return a choice from named options, a score on a defined rubric, or a probability for a yes-or-no question. The examples cover startup assumptions, draft clarity, agent actions, task routing, context selection, and claim-versus-evidence checks. Sample inputs work without an account. The site also offers TypeScript export, an API request builder, an MCP configuration generator, and a cost calculator. Jev AI Tools is not affiliated with TypeSafe AI.
