CodeDesign AI の入門

Before you build anything, finish this one-time setup.

Here’s what my own first run looked like:

ステップ3：最初のプロジェクトを開始する

Click New Project and describe your idea in one or two sentences.

CodeDesign AIのプロ向けヒントとショートカット

After eight months in the editor, these are the tips that saved me the most time.

キーボードショートカット

アクション	ショートカット
最後に行った変更を元に戻す	Ctrl / Cmd + Z
変更をやり直す	Ctrl / Cmd + Shift + Z
選択した要素を複製する	Ctrl / Cmd + D
プロジェクトを保存	Ctrl / Cmd + S

ほとんどの人が見逃す隠れた機能

AI Companion: Talk to your site in plain words. Type hey, make the hero section darker and it applies the edit for you.
AI Vibコーディング： A second editor that rebuilds site structure and design from AI prompts instead of clicks. Both 編集者 edit the same project.
Stock photo search: Skip the upload step entirely and let the AI find a picture that fits your page.
ヘルプセンター: Tutorials, videos, and guides sit one click away when a feature does not behave as expected.

These are the extras that make the platform worth learning properly:

CodeDesign AIでよくある間違いを避ける方法

Mistake #1: Publishing the first AI draft as-is

❌ 間違い: Generating a site, glancing at it, and hitting publish the same minute.

✅ 右: Read every headline first. The AI gets structure right and details wrong, so fix specifics before you launch.

Mistake #2: Writing a vague prompt

❌ 間違い: Typing make me a business website and hoping artificial intelligence reads your mind.

✅ 右: Name your industry, audience, tone, and the pages you need. Detailed prompts produce a much closer first draft.

間違いその3：モバイルプレビューをスキップする

❌ 間違い: Checking the desktop view only, then wondering why signups stall.

✅ 右: Preview every page on phone width before publishing. Most traffic arrives on a small device.

CodeDesign AIのトラブルシューティング

Problem: The AI generated the wrong kind of site

原因： The prompt was too short, so the AI filled the gaps with generic assumptions.

修理： Rewrite the prompt with your industry, audience, and page list, then regenerate. Keep the version you prefer.

Problem: My custom domain shows an error

原因： DNS records have not propagated, or they point somewhere else.

修理： Recheck the records at your registrar and allow 48 hours. Republish once the domain resolves.

Problem: The layout breaks on mobile

原因： A section was sized manually and overrides the responsive defaults.

修理： Reset that element’s width, then use visibility settings to hide anything that does not fit small screens.

📌 注記： If none of these fix your issue, contact CodeDesign AI support through the help center.
