JuriSpy — Kim Haklı?

#01 The product

JuriSpy ("Kim Haklı?" — Turkish for "Who is right?") turns everyday disagreements into court cases. Users write up their dispute, add testimonies and evidence, let friends vote — then an AI judge reads everything and delivers a verdict with a written justification.

Verdicts are deliberately entertaining: the product goal is verdicts that make everyone laugh while still feeling fair. Contested rulings can go to appeal, where a second AI pass reconsiders the case. Verdict cards are designed for sharing — the growth loop is people posting their wins.

#02 Engineering

A React + TypeScript progressive web app (installable, offline-capable via service worker) with a Node.js backend and Supabase for data and auth. Verdict generation runs through OpenAI with structured prompts that consume the full case: title, story, testimonies, votes, and evidence.

Privacy handling is explicit: case content is processed only to generate the requested verdict, verdicts are stored for the case owner, and user content is never used to train models. Gamified achievements (first verdict, shared verdict cards) drive retention.
