My Motivation

Developers are becoming increasingly dependent on quick code fixes and instant code generation. When we use external AI tools, there's no middle ground - the AI just gives you the answer. People copy-paste solutions without understanding the why behind them.

This approach makes us lose the core skill that makes a software engineer valuable: understanding the problem and solving it systematically.

AI is best for breaking down complex errors into very easy and understandable explanations. I believe CoachLint will help developers learn more deeply instead of developing shallow programming skills.
