AI consumer fortune-telling SaaSLive
간지사주
A 256-page mobile-first fortune-telling platform with Toss payments, coin economy, idempotent refunds, classical-text RAG, and push dispatch.
Overview
Ganji Saju productizes Korean fortune-telling content as a mobile SaaS experience.
It combines Toss payments, coin credits, refunds, settlement, web push, and classical-text RAG into one consumer product. Large route sets are prerendered for fast mobile access, and AI readings are grounded with source references.
Its strength is combining the fun of a content app with the operational discipline of paid SaaS. Generation, payment idempotency, monetization, and push retention work as one product system.
