## Overview

ISIG turns a user's spoken or typed work knowledge into an AI-guided interview and then a checklist-style handoff document. The visible workflow starts with Google sign-in, continues through topic selection and follow-up questions, and ends with a rendered report and document-library or sharing views. The sampled interview page confirms requests to the interview API; the generate-document route confirms AI document generation. The README describes unique-link sharing, but the dynamic document pages and parts of interview persistence were not sampled, so those connections are left uncertain.

Main entry points: [`app/interview/page.tsx`](https://github.com/jjaanngg/renewal_isig/blob/main/app/interview/page.tsx) (Interview flow), [`lib/supabase.ts`](https://github.com/jjaanngg/renewal_isig/blob/main/lib/supabase.ts) (Supabase client), [`app/api/generate-doc/route.ts`](https://github.com/jjaanngg/renewal_isig/blob/main/app/api/generate-doc/route.ts) (Document generation API), [`app/login/page.tsx`](https://github.com/jjaanngg/renewal_isig/blob/main/app/login/page.tsx) (Google sign-in)
