What your results will look like
Press Analyze to get real results like these for your own text.
Three kinds of answers, ready to use
Each analysis asks several questions in one request, so answers arrive together and don't influence each other.
Yes/No probability
the API calls it “Noul”
Ask a yes/no question about your text and get a probability between 0 and 1 — for example, “Is this ticket urgent? → 93%”.
“Is this ticket urgent?” → 0.93
Classification
the API calls it “Choice”
Sort text into one category — billing, complaint, purchase inquiry — and see the probability for every option, not just the winner.
“Category?” → billing 0.88 · technical 0.12
Scoring
the API calls it “Score”
Rate text on a scale, like customer frustration from calm to furious. Scores can land between levels and include the model's own confidence.
“Frustration?” → 2.4 / 4 · confidence 0.9
Ready-to-use scenarios
Each scenario asks up to three fixed, tuned questions, so results are consistent and comparable every time.
Support ticket triage
Route inbound support tickets: which category the issue belongs to, how likely it is urgent, and how frustrated the customer sounds.

- Urgency
- Customer emotion
Review sentiment
Understand product reviews at a glance: overall sentiment, how satisfied the reviewer is, and whether they would recommend the product.
- Sentiment
- Satisfaction
- Recommendation
Message intent
Read inbound messages fast: what the sender wants, how likely they are to buy, and how strong a sales lead the message is.
- Intent
- Purchase intent
- Lead strength

Frequently asked questions
What is this site?+
ai-jev.net is a free playground for Jev, the structured-decision AI model served through the official TypeSafe API. You paste text, and instead of generated prose you get typed answers: categories, probabilities and scores that software (or you) can act on directly.
Is it really free? Do I need an account?+
Yes, it's free and there is no sign-up. Your first visit grants a one-time allowance of 10 free credits, and each analysis costs 3 credits — enough for 3 full analyses. The grant does not refresh daily. Paid credit packs may arrive later; nothing is charged today.
What kinds of text can I analyze?+
The playground offers three ready-made scenarios: support ticket triage, review sentiment and message intent. Each runs up to three fixed questions optimized for that scenario. The underlying API supports custom questions too — that's what the paid product will build on.
What happens to the text I submit?+
Your text is sent over HTTPS to our server and forwarded to the TypeSafe API, which performs the analysis. We do not store your text after the response returns, and we don't put it in logs. TypeSafe's public documentation states that models are not trained on customer requests or responses. See our Privacy Policy for details.
How accurate are the results?+
Results are probabilistic model estimates, not guarantees. A 90% urgency probability means the model believes urgency is very likely — not that it is 90% certain to be right in every case. Confidence values measure the model's own certainty per answer and are separate from option probabilities. Review important decisions before acting on them.
Why did my analysis say the daily budget is used up?+
This site funds all free analyses from a shared daily and monthly budget. When other visitors have used up a day's budget, real analyses pause until it resets (the message shows the exact reset time in UTC). Credits are never charged for a request that was paused this way.
Are you affiliated with TypeSafe?+
No. ai-jev.net is an independent tool that calls the official TypeSafe API. We are not affiliated with, endorsed by, or sponsored by TypeSafe, and 'Jev' and 'TypeSafe' are trademarks of their respective owners.
Which model powers the analyses?+
Analyses run on the Jev model through the TypeSafe API. The exact model version is shown with every result (for example jev-1.13.0, currently behind the jev-latest alias).
