Build and test conversational workflows with Jev. See why each step happened, save conversations as tests, and catch wrong turns before you ship. Export runnable TypeScript, workflow JSON, and an integration skill for your coding agent. Free and open source. Bring your own key for live runs.
Hey Product Hunt!
An AI workflow can reach the right answer after taking the wrong path. Jev State helps you see those steps and test them.
Start with an example, write the rules for each state, and try a conversation with live Jev. Save it as a test and check the steps along the way, not just the final result.
When you are ready to build, download the workflow JSON, runnable TypeScript, tests, and a SKILL.md that helps your coding agent fit it into your app. You can import the same JSON later to keep editing.
The app is free and open source. Live runs use your own TypeSafe key and are billed by the provider. There is also a key-free simulation mode for checking the wiring.
What would you try first: support routing, onboarding, or something else?
