この連載は、

技術初心者・非エンジニアの私が、ChatGPT を相棒にしながら
Next.js で Webアプリ（ブックマークアプリ）を 0 から作り切るまでの 24 日間の記録

です。

よくある

「プロンプト投げたらツールが全部やってくれる」
「AIにコード書かせてコピペして終わり」

みたいな話ではなく、

手を動かすのはあくまで自分
ChatGPT は先生・相棒・レビュー係
わからないところを、その場で聞きながら進める

というスタイルで進めていきます。

「非エンジニアでも、ChatGPT をうまく使えば Webアプリ開発ってここまでできるのか」という リアルなドキュメント にしたいです。
