Step 1

What is DeepSeek AI?

DeepSeek is a state‑of‑the‑art large language model that excels at code generation. You can describe your Chrome extension idea in plain English, and it will write the complete manifest.json, HTML, CSS, and JavaScript files for you – fully functional and ready to test.

No coding skills are needed. You just need a clear idea of what the extension should do (e.g., replace the new tab page with a to‑do list, display a random quote, or block distracting websites).

How It Works DeepSeek understands Chrome extension architecture, permissions, and APIs. It can generate code that follows the best practices and is ready to load into Chrome's developer mode.

Step 2

Plan Your Extension Idea

Before asking AI to write code, decide what your extension will do. Here are three beginner‑friendly examples:

• 📅 Motivational New Tab: Replaces Chrome's new tab page with a beautiful background and a random inspirational quote.
• ⏱️ Simple To‑Do List Popup: Click the extension icon to open a small popup where you can add and check off tasks.
• 🎨 Background Color Changer: Adds a button that changes the background color of any webpage to a random color.

We'll build the Motivational New Tab extension because it's visually impressive and easy to customize. You can later modify it with your own quotes and images.

Step 3

Let DeepSeek AI Write All the Code

Open DeepSeek Chat and paste the following prompt. The AI will generate the complete code for your extension in one go.

DeepSeek Prompt

Create a Google Chrome extension that replaces the new tab page with a motivational design.
Requirements:
- A manifest.json file (Manifest V3)
- A newtab.html page with a beautiful gradient background, a large clock showing the current time, and a random motivational quote that changes every time you open a new tab.
- Include a folder named "icons" with a 128x128 icon (use a placeholder SVG or data URI).
- The quote should come from a JavaScript array of 15 quotes.
- Add a small author credit at the bottom.
- Style everything with modern CSS and make it responsive.
- Provide the complete file structure and code.

DeepSeek will output the entire project. It will look something like this (the generated code is ready to copy):

manifest.json (AI‑Generated)

{
  "manifest_version": 3,
  "name": "Motivational New Tab",
  "version": "1.0",
  "description": "A beautiful new tab page with a clock and inspirational quotes.",
  "chrome_url_overrides": {
    "newtab": "newtab.html"
  },
  "icons": {
    "128": "icons/icon128.png"
  }
}

Copy each generated file into separate text files as we'll assemble them next.

Step 4

Create Your Extension Folder & Files

Create a new folder on your computer called motivation-tab. Inside it, create the following files using a text editor (Notepad, VS Code, etc.):

1. manifest.json – the configuration file that tells Chrome about your extension.
2. newtab.html – the HTML structure for the new tab page.
3. style.css – all the styling (you can embed it in newtab.html or keep separate).
4. script.js – the JavaScript for the clock and random quotes.
5. icons/icon128.png – a 128×128 pixel icon. You can use any PNG image or even a solid color square.

If DeepSeek didn't provide an icon file, you can create a simple 128×128 colored square in Canva or use an online favicon generator. Even a placeholder icon works for testing.

Pro Tip Name your folder exactly as you want it, and keep all files in the root. The manifest must be at the top level, not inside a subfolder.

Step 5

Install & Test Your Extension Locally

1. Open Chrome and go to chrome://extensions/.
2. Enable “Developer mode” in the top‑right corner.
3. Click “Load unpacked” and select the motivation-tab folder you created.
4. The extension will appear in your list. Open a new tab – you should see your motivational page with a clock and quote!

If something doesn't work, click “Errors” on the extension card to see what went wrong. Common issues include missing files or syntax errors. Go back to DeepSeek, paste the error, and it will help you fix it.

Troubleshooting If the new tab still shows the default Chrome page, make sure your manifest's chrome_url_overrides is correct and there are no typos. Sometimes you need to remove and re‑load the extension.

Step 6

Publish Your Extension on Chrome Web Store

Ready to share your creation? Here's how to publish it:

1. Go to the Chrome Web Store Developer Dashboard and pay a one‑time $5 registration fee.
2. Click “New Item” and upload a ZIP file of your extension folder.
3. Fill in the store listing: name, description, screenshots (1280×800 or 640×400), and promo images.
4. Choose the appropriate category and submit for review.

Review usually takes 1‑3 business days. Once approved, anyone can install your extension from the Chrome Web Store!

Privacy Requirements If your extension collects any data, you must provide a privacy policy URL and explain data usage in the dashboard. For a simple new tab extension, you can state “No data collected”.
