Tool

Turn an LLM prompt into Jev decisions

Paste an existing LLM prompt and see which parts are bounded decisions you can move to Jev, and which should stay with the LLM. The analyzer splits your prompt into responsibilities and generates a Decision Spec for each Jev step.

Up to 5,000 characters. Your prompt is not stored — it lives only in your browser session.

How it works
1

Paste your prompt

Any LLM prompt — system prompt, few-shot, or chain-of-thought.

2

See the split

Each part of your prompt is labeled: Jev, LLM, or code.

3

Generate specs

Each Jev step gets an editable Decision Spec and code template.

How Prompt to Jev works

Most LLM prompts do more than one thing. A single prompt might classify input, make a decision, generate text, and check the output — all in one call. Prompt to Jev separates those responsibilities so each one uses the right tool.

The analyzer reads your prompt, identifies each instruction, and labels it: Jev for bounded decisions, LLM for text generation, code for deterministic operations, or Hybrid for mixed steps that need splitting.

What moves to Jev, and what stays

Moves to Jev
  • "If the customer asks for a refund, check eligibility" → Jev Noul
  • "Categorize the complaint" → Jev Choice
  • "Rate the urgency" → Jev Score
  • "Decide whether to escalate" → Jev Noul
Stays with LLM
  • "Draft a polite reply" → LLM generation
  • "Summarize the conversation" → LLM summarization
  • "Explain the policy" → LLM explanation
  • "Translate the response" → LLM translation

Example: a customer support prompt

Here is how the sample prompt above gets split:

1Read the customer's messageCode
2Check if the order is within 30 days (refund eligibility)Jev Noul
3Categorize the complaint as quality, shipping, or billingJev Choice
4Draft a polite reply addressing their concernLLM
5Flag reply for human review if refund/compensation mentionedJev Noul
6Look up order status (shipping inquiry)Code

The original prompt did everything in one LLM call. After splitting, three steps move to Jev (deterministic, typed, no retries), one stays with the LLM (text generation), and two become plain code.

Generate the implementation

After the split, each Jev step gets an editable Decision Spec and code templates in TypeScript, Python, and cURL. You can refine the spec — adjust options, criteria, fallbacks — before generating the final code.

The code templates are deterministic and versioned. Running any implementation requires your own access to Jev from TypeSafe AI. Jev is in Early Access, so the API may change — always validate before production.

FAQ

Frequently asked questions

No. It does not rewrite or optimize the full prompt. It splits the prompt into responsibilities, labels each one, and lets you migrate the bounded decisions to Jev.
