Introduction: Why it was Achieved in 1 Week
Normally, building a chat app like Slack or an SNS by oneself, including design, implementation, and testing, takes at least 3 months.
However, by partnering with Genspark, a powerful tool, I accomplished this in just 1 week. This is not magic; it's reproducible by anyone with the right tools and strategy.
Overview of the Developed App
What I developed this time is not a simple app like a To-Do list. It's a full-fledged application with 22,500 lines of code and includes the following features:
- User authentication system
- Real-time chat functionality
- Database integration
- Responsive UI design
The record, openly disclosing cost-effectiveness, 18 freezes during development, and more, is provided below.

"Handing Everything Over" to AI Will Fail
What's important here is that it's not a matter of "just relying on AI to do everything automatically."
During development, I repeatedly encountered AI-specific issues like "forgetting instructions" and "inconsistent quality." While AI is smart, it doesn't remember all contexts like a human.
What I introduced then were "Prompting Techniques to Make Claude Repeat Instructions" and my unique quality control method, the "Eric George Method (V-model)." If you start development without knowing these, you will fall into a bug-fixing loop and surely get frustrated.

For Those Starting Out
Genspark is a very powerful tool, but to master it, your "ability to give instructions to your partner (AI)" is crucial.
My blog shares all the know-how, including not only success stories but also failures and troubleshooting. Please refer to the technical articles on this blog and try creating your own application.
