It's great that you can compare the same project using 3 different AIs. It was nice to be able to quickly check the differences in results from each AI~

This course is a development manual that comprehensively guides you through the process of developing a Spring Boot-based web bulletin board using various AI tools such as Claude, Gemini, and OpenAI Codex. While the initial environment setup methods differ for each AI tool, the core processes for developing actual bulletin board functionality (backend, frontend, file upload) use the same prompts.
