Step 1

Create a 3D Animated Video Using AI

First, we need an eye‑catching background video. We'll use GoFlow (or any AI video generator) to produce a short, looping 3D animation related to your website's theme.

1. Go to GoFlow and create a new project.
2. Set dimensions to 16:9 (1920x1080) and duration to 10 seconds.
3. Enter a prompt describing the scene. For a phone shop: "3D rotating smartphone on a neon platform, floating particles, dark futuristic background, cinematic lighting".
4. Click Generate and download the video once ready (720p is fine).

Pro Tip: Keep It Short & Clean The video will play in the background of your website. Avoid busy scenes; a simple 3D loop with a product mockup works best.

Step 2

Organize Your Project Folder

Create a new folder on your computer (e.g., my-3d-site). Move the downloaded video into this folder and rename it to something simple like video1.mp4.

This folder will be the workspace for the AI website builder. The tool will read the video and generate all website files inside it.

File Naming Use only lowercase letters and numbers. Spaces or special characters may break the AI's ability to locate the file.

Step 3

Get the AI Website Builder (Anti Gravity)

We'll use Anti Gravity, a powerful AI tool that builds complete 3D websites from a simple prompt and a video file. It's free to use and works directly on your desktop.

1. Search for "Anti Gravity" (or "Anti Gravity AI") and download the desktop application.
2. Install and open it. Sign in with your Google account.
3. Click Open Folder and select the folder you created earlier (the one containing video1.mp4).

Once the folder is loaded, you'll see your video file listed. Now we need the magic prompt.

Step 4

Generate the Full Website with a Prompt

Inside Anti Gravity, you'll find a text box where you can paste the site creation prompt. This prompt tells the AI exactly how you want your 3D website to look, what sections to include, and how to use your video.

Below is a complete, ready‑to‑use prompt. Copy it, paste it into the tool, and don't forget to replace video1.mp4 if you used a different filename.

Master Website Prompt

Create a futuristic 3D animated single‑page website for a smartphone store. 
                Use the video file "video1.mp4" as a full‑screen background hero video.
                The website must include:
                - A sticky navigation bar with logo and menu links (Home, Products, About, Contact).
                - Hero section with a bold title, subtitle, and a glowing "Shop Now" button over the video.
                - Products section with 3D card animations showcasing 3 smartphones with prices and "Buy" buttons.
                - Features section with animated icons and smooth scroll‑triggered fade‑ins.
                - Testimonials carousel with user avatars.
                - Contact form with floating labels.
                - Footer with social media icons.
                - Overall style: dark theme, neon purple and cyan accents, glassmorphism cards, smooth 3D parallax effects, responsive design.
                - All text content should be generic placeholder, ready to edit.
                - Generate a complete index.html, style.css, and script.js in the same folder.
                - Use only vanilla HTML, CSS, and JavaScript. No external frameworks except Font Awesome for icons.
                - Ensure the video loops automatically, muted, and plays inline.

Paste the prompt and click Send. The AI will start building your website. It may take a few minutes and might ask for confirmation – always reply "yes" or "continue".

Stay Patient The generation process creates multiple files. Do not close the tool until you see a success message. If it stops, simply type "continue" and press Enter.

Step 5

Customize & Preview Your Site

Once the AI finishes, open the folder. You'll find index.html, style.css, and script.js. Double‑click index.html to preview it in your browser.

You can now edit the text, change colors, or add your own images. The code is clean and well‑commented. Use any code editor (VS Code, Notepad++) to make adjustments.

To host your site, simply upload the entire folder to any static hosting service (Netlify, Vercel, GitHub Pages, or even Google Drive).

Step 6

Final Checklist & Pro Tips

• 3D video generated and downloaded
• Video placed in project folder, renamed correctly
• Anti Gravity installed and folder opened
• Master prompt pasted and sent
• Website files generated successfully
• Previewed in browser, all animations work
• Customized text and images to match your brand

Extra Tips:

• For a different industry (car dealership, restaurant, real estate), simply modify the prompt – describe the new theme and keep the same structure.
• If the AI misunderstands, reply with clear instructions like "change the color scheme to blue and white" – it can edit the generated code.
• Use ChatGPT to tailor the prompt before pasting it into Anti Gravity. Just say: "Give me a website generation prompt for a [your business] with a 3D background video."
