What it is
kojev is an unofficial Kotlin Multiplatform client (JVM, Android, iOS) for Jev, TypeSafe AI's System One model. It lets Kotlin developers ask typed Choice, Score, and Noul questions about serializable state and receive answers as their own enums and probabilities.
How it uses Jev
kojev asks Jev Choice, Score, and Noul questions about any @Serializable state. Choice returns the chosen enum value, all option probabilities, and confidence; Score returns the distribution over your enum, the most likely level, the mean, and confidence; Noul returns only a probability. Results are read through one typed API.

Technique worth stealing
Encode option and level descriptions directly on the enum via Criterion, so the rubric lives next to the constants and missing descriptions fail compilation.
Try it
Add io.github.itisnomatter:kojev:0.1.0 and a Ktor engine, then create a JevClient with TYPESAFE_API_KEY.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
