What is Jev and How to Use it?

Learn what Jev by TypeSafe is, how it makes fast, structured AI decisions, and how to use it in your applications.

In this video, I cover:
- What Jev is and why you might use it
- How Jev differs from other LLMs
- Jev’s speed and pricing
- How state, questions, and answers work
- The three question types: Noul, Choice, and Score
- Getting started in the TypeSafe Playground
- Making requests with the TypeScript SDK
- When to use Jev—and when to use something else

For the demo, we analyze customer messages to detect frustration, classify requests, and score frustration levels. We start in the Playground, then make the same kinds of requests from TypeScript and use the results in code.
