Sign in to run a Jev evaluation

JevStation keeps your Jev evaluations and credits in one place. It takes a few seconds.

Run your first evaluation

Paste a support ticket, a review, or a chunk of spec. Jev returns typed answers — a choice, a score, or a yes/no — with probability distributions your code could branch on.

  1. 1. Context

    Optional. Sent as part of the state, alongside the conversation.

  2. 2. Questions

    Every question is evaluated independently against the same state, so asking more costs little extra latency. Score and Choice answers include confidence; Noul returns a probability only.

  3. 3. State

    Paste the text you want judged, choose the questions, and get typed answers with probabilities and confidence — not prose.

Try one of these

  • Hi, I've been trying to connect my Stripe account for 3 days and it keeps failing. I'm losing sales. Please help ASAP.

  • The invoice for March was issued on the 1st and settled on the 14th. No further action is needed on your side.

  • Works fine for basic edits, but the export crashed twice on a 40-page file. Support replied within a day, which was good.

  • Migrate the billing service off the legacy queue. Requires dual-write for two weeks, a backfill of 4.2M events, and a tested rollback plan before cutover.
