What you can build with Jev
Jev shines on the small, fast, high-volume judgments software makes all day. Here are concrete things teams build with it — every one runs live in the playground with a real API call.
The pattern never changes: hand Jev a state and a few typed questions (choice / score / noul) and get back calibrated answers your code branches on. Pick a scenario to load the exact request:
Coding & AI agents
The small, high-frequency decisions inside an agent loop — routing, gating, retrieval and verification.
Agent skill routing
choicenoulPick which skill or tool a coding agent should use for a request — or decline when none fit.
See the use case →Repo context selection
scorenoulRank which files are actually relevant to a task before spending context (and tokens) on them.

noulscoreBefore an agent stops, ask Jev whether the work is actually finished and the claims hold up.
See the use case →Content & marketing
Judge, score and tag content at scale — the analysis jobs, not the writing.
Viral post analysis

choicescorenoulBreak a live ad into hook, offer, CTA and awareness stage — the tagging behind teardown of 724 ads across 37 brands.
See the use case →SEO internal linking
