Problem

When people in their 50s try to issue documents on Gov24 (Korea's government services portal) — such as resident registration certificates, income verification, or tax payment certificates — they face 5+ authentication methods (joint certificate, financial certificate, simple auth, Digital OnePass, etc.) and the UI changes every year, causing confusion each time. They end up visiting the local government office in person (wasting 30 minutes to 1 hour) or asking their children to do it for them.

Solution

Users select the document they need, and the service provides a step-by-step guide mirroring the actual Gov24 screen flow — showing which buttons to click, which authentication to select, and what to enter, all with screenshot-based visual guides. Includes a pre-requisite checklist for each authentication method and solutions for commonly encountered errors.

Target: Age 48–65, users who struggle every time with Gov24 or HomeTax, wanting to reduce in-person visits to government offices
Revenue Model: Guides for top 10 documents free. Full document guide library + error resolution chatbot at $2.20/month (2,900 KRW). Future revenue from administrative agent referral fees.
Ecosystem Role: Education
MVP Estimate: 2_weeks
