Learn to Build Websites with ChatGPT

website.co.jp is a free training site for people who want to build real websites with ChatGPT without getting buried in confusion. This site teaches a practical sequence: define the site, decide filenames, make and organize images, save files locally, upload carefully, use common CSS and JavaScript, build detail pages first, make section indexes later, make the homepage last, and grade the final result honestly.

Why website.co.jp Exists

Too many people have the ideas, but not a clean production method. This site is here to fix that.

Because websites became too opaque

Many site owners ended up dependent on systems, files, and workflows they could not inspect or explain. website.co.jp pushes back against that.

Because AI reopened practical building

ChatGPT can now help people build real sites, but the work still needs structure. This site teaches that structure.

Because sequence beats chaos

A calm order of operations is often more valuable than random speed. This site is built around that belief.
