Jev Knows
Human wisdom, weighed for your choice.
Jev draws on patterns in what people have written, learned and lived through, and shows which way that knowledge leans for a choice like yours. It can be wrong, and it cannot see your future.
How Jev reads a question
Ask it plainly
One decision, framed as yes or no. The more of your situation you put in, the sharper the read.
See where the wisdom leans
Jev looks for patterns in what people have written about choices like yours, and shows how much of that wisdom points to yes.
See what would move it
Add a detail and Jev reads again, up to five times. Every read stays stacked, so you can swipe back and compare.
The model behind Jev Knows
Jev Knows runs on Jev, a decision model from TypeSafe AI. Instead of writing an answer, a decision model returns how likely something is, which is why every read here is a number first.

What is Jev Knows?
Jev Knows is a free decision tool. Ask a yes-or-no question and it shows which way human experience leans, as a percentage, with the factors behind it. It is a second opinion, not an instruction.
How does Jev decide between yes and no?
Jev scores your question on six factors: goal fit, whether the downside is manageable, how easy it is to reverse, timing, whether you have enough information and whether the opportunity cost is worth it. Together they give the overall lean.
What does the percentage mean?
It shows how strongly the knowledge Jev draws on leans one way for a choice like yours. It is not the chance that things will work out, and asking again can give a slightly different number.
Is Jev Knows free?
Yes. You can ask up to 10 questions a day (UTC) without an account.
Does Jev Knows keep my question?
Your question text is not stored unless you choose to share a read. Your recent questions stay in this browser only.
Should I rely on Jev for medical, financial or legal decisions?
No. For medical, financial or legal matters, consult a qualified professional. Jev can help you think, but the choice stays yours.
