Give it state
Use a ticket, message, form fields, or the structured context your agent already sees.
state = ticket.textJev · a decision tool for software teams · Jev AI
Jev handles classification, routing, scoring, and safety checks—give it state and get a result your code can use.

Output
From input to action
Jev does not ask you to rewrite your system. Separate state, questions, and the next action; the model only handles the decision in the middle.
Use a ticket, message, form fields, or the structured context your agent already sees.
state = ticket.textDescribe the decision with choice, score, or noul. Ask multiple questions in one request.
questions = { intent, urgent }Use the result and its probability to queue, route, block, or request review. Your system keeps control.
if result.urgent: escalate()Online playground
Enter a real scenario, define typed questions, and inspect a typed decision with probabilities.
Where it fits
The hardest product work is often not generating a paragraph. It is making small decisions many times a second without losing control.
Define possible answers up front and pass the result into functions, workflows, and databases.
Classify, score, and answer yes-or-no questions together instead of chaining separate calls.
Use probability or confidence to decide whether the system should continue automatically or ask a person.
Use it inside if, route, guardrail, and queue logic without another chat surface.
A consistent request shape, explicit schemas, and manageable API keys take you from test to production.
Start with question types and state inputs, then follow an SDK or REST example into your system.
Where it connects
Jev handles the decision itself. Your product still decides which model to call, when to queue, and when to ask a person.
Assess task difficulty first, send simple requests to a faster model, and escalate only when needed.
Check intent before a tool executes. Ask for confirmation around deletion, payment, or other sensitive actions.
Classify intent, urgency, and human-review needs together so tickets take the right path.
Decide which tool results still matter and preserve source details when context is compressed.
Designed for developers
Understand Jev in the playground, create an API key, and connect a validated decision workflow to your product.

Drop the decision into an existing service

The docs follow the path developers actually take: understand the model, define questions, send state, and wire probabilities into code.
Open full docsCreate an account, prepare your first state and questions, and inspect the typed decision in the response.
Use choice, score, and noul for classification, continuous scoring, and yes-or-no decisions. Ask multiple questions in one request.
Create an API key, follow the SDK or REST example, and use probabilities and confidence to drive your application logic.
Jev currently accepts text, JSON objects, and arrays of text. Images, audio, and video are not supported yet; validate accuracy separately for non-English inputs.
Jev AI turns unstructured state into typed decisions with probabilities for classification, routing, scoring, and safety checks. Choose monthly, yearly, or one-time access for your usage.
