What it is
A web app that evaluates startup ideas for indie hackers. You describe an idea, and it returns a verdict — KILL IT, FIX IT, or SHIP IT — plus scores, a best signal and biggest risk.
How it uses Jev
One request asks Jev 10 questions in parallel: 8 indie-hacker questions scored 0–4, plus category and understandability. Each score ×25, weighted average across the 8, then a clarity gate below 0.3 understandability, producing the KILL/FIX/SHIP verdict in api/evaluate.ts.
Primitives:scorechoice
Technique worth stealing
Map each Jev 0–4 score to 0–100, weight per goal, gate low clarity before showing a verdict.
Try it
npm install; cp .env.example .env with TYPESAFE_API_KEY; npm run dev (http://127.0.0.1:5317).
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.
