I Can’t Code, But I Built a Browser Extension with AI

A True Story(👉 Click here to download and try it for free)

Last Friday night, I had an idea: What if I could build a tool to scrape product info from AliExpress and import it directly into my Shopify store with one click?

As someone with zero programming knowledge working in e-commerce, this idea seemed impossible.

But then I tried Claude (an AI assistant).

The result: 48 hours later, the extension was real.

This article documents the entire journey. I want to show you: In the AI era, not knowing how to code doesn’t matter anymore.

First Night: From Zero to Working (2 Hours)

My First Words to Claude

“Help me build a browser extension that can scrape product information from sites like AliExpress and Amazon.”

That’s it. One simple sentence. No technical jargon.

What Claude Did

It immediately understood what I needed, then:

30 minutes – Generated all code files
Told me how to install – Step by step
Explained what each file does – In plain English

All I had to do:

Download files
Click a few buttons in Chrome
Done!

The moment I saw it work for the first time, I was stunned.

The extension could actually recognize which website I was on and scrape product titles, prices, and images. Tasks that used to take me 10 minutes of copying and pasting now took 30 seconds.

The Comparison

Before:

1. Open AliExpress product page
2. Copy title
3. Right-click save images
4. Note down price
5. Organize in Excel
6. Per product: 5-10 minutes

Now:

1. Open product page
2. Click extension icon
3. Click "Start Scraping"
4. Done!
5. Per product: 30 seconds

Day Two: Real Use, Real Problems

Problem 1: Shopify Import Failed

Saturday morning, I excitedly tried importing data to Shopify. Result:

❌ Error: Title too long (maximum 255 characters)

I sent Claude a screenshot: “Why is this happening?”

Claude’s Response Amazed Me

It not only explained the reason:

AliExpress titles are often very long
Shopify has character limits
Need auto-truncation

More importantly, it immediately improved the code and told me ALL Shopify field restrictions.

20 minutes later, problem solved.

Problem 2: AliExpress Not Working

That afternoon, I discovered some AliExpress product pages returned no data.

I sent Claude another screenshot.

This time, its analysis went deeper:

AliExpress had a redesign with new page structure
Need to add more detection methods
Some images are lazy-loaded

Then it rewrote the scraping logic using 15 different methods to find product information.

Like a detective: if one clue doesn’t work, try another.

Saturday Evening: Pursuing Excellence

Problem 3: Incomplete Data

It was working, but I noticed:

Only 1 image captured (product had 6)
No product videos
Description too brief

I wanted more complete data.

Claude’s “Upgrade”

This conversation was interesting. I said: “I want all images, plus video links.”

Claude asked me questions:

“Images – all of them or just the first few?”
“Videos – download or just links?”
“Description – how detailed?”

Then it spent several hours (I watched the code being generated) doing a major upgrade:

v3.0 Capabilities:

📸 Scrape up to 10 high-res images
🎥 Find product video links
📝 Complete product description (3000 chars)
⭐ Rating and sales data
📊 Product specifications

The Interface Got Smarter Too

Now the extension shows me data completeness:

Product Title
Price: $97.11

[📸 5 Images] [🎥 1 Video] [📝 Has Description]

Green means yes, red means no. Crystal clear.

Sunday: The Toughest Challenge

The Description Problem

Sunday morning, I found imported product descriptions only showed:
“Smarter Shopping. Better Living! Aliexpress.com”

This wasn’t the product details I wanted!

Claude’s Honesty

This time Claude was very honest:

“AliExpress descriptions are hard to scrape because:

Some are in tabs, hidden by default
Some are dynamically loaded
Some are even in image format”

But it didn’t give up.

It gave me three solutions:

Solution A: Improve the extension

Add more scraping methods
Taught me how to use it (“Scroll to page bottom, wait for loading”)

Solution B: Gave me a script

// Run this code in browser console
// One-click extract and copy description

Solution C: AI Rewriting
“If that still doesn’t work, give the product info to ChatGPT and let it write a professional description.”

My Takeaway

This impressed me deeply.

Claude wasn’t arrogant like “I’m AI, I can do everything.” Instead:

Acknowledged technical limitations
Provided multiple solutions
Gave me the choice

That’s what a good AI assistant should be.

The Most Important Things I Learned

1. AI Isn’t Magic, It’s a Tool

At first I thought just telling AI “make an extension” would make it appear.

In reality, I needed to:

✅ Clearly describe requirements
✅ Test and give feedback (screenshots are important!)
✅ Make choices (which of multiple solutions)
✅ Understand basic concepts (even without coding)

AI is an amplifier – it amplifies your ideas and judgment.

2. Technical Barriers Have Really Lowered

I know absolutely nothing about:

JavaScript
HTML
CSS
Chrome extension development

But I built a working product.

Why?

Because I understand:

✅ What my needs are
✅ What a good product looks like
✅ What problems users will face
✅ How to test and improve

These are what matter.

3. It’s About Solving Problems, Not Code

Throughout the process, I never fully understood the code (just got the gist).

But I knew:

Is this feature right
Is this experience good
What’s still missing

That was enough.

Code is Claude’s job, product is mine.

Advice for Those Who Want to Try

You Don’t Need:

❌ To learn programming
❌ To know technical terms
❌ Computer science background
❌ To be young (I’m in my 40s)

You Need:

✅ A clear need
✅ Willingness to try and learn
✅ Ability to express problems clearly
✅ Patience (you’ll hit roadblocks)

How Exactly?

Step 1: Think through what you want

Don’t say “I want to make a website,” say:

“I want a tool that can do xxx”
“I hope it can do yyy”
“The users are zzz”

Step 2: Talk with AI

Like chatting with a friend
Screenshot problems when you hit them
Ask when you don’t understand

Step 3: Test and improve

Use it yourself first
Report problems as you find them
Improve bit by bit

Step 4: Don’t pursue perfection

Good enough is good enough
Ship first, improve later
80-point product beats 100-point plan

Why Claude Is Impressive

After all this time, here’s what I learned:

1. It Really “Gets” You

No need for technical jargon, just speak normally.

I said “AliExpress not working,” and it knew:

To analyze AliExpress page structure
To test different scraping methods
To consider edge cases

2. Proactive Thinking

It doesn’t just answer questions, it:

Anticipates potential problems
Provides multiple solutions
Explains why it does things this way

For example, when fixing field length limits, it didn’t just fix the title – it proactively checked description, images, and all other fields.

3. Patient

I asked “why” countless times. It answered seriously every time.

Sometimes asking the same question from different angles, it would explain in different ways until I understood.

4. Honest

When something can’t be done, it says so directly:

“This is technically difficult because…”
“I suggest this alternative…”
“You might need to handle this part manually”

No false “AI can do anything” promises.

5. Continuously Learning

Throughout the process, it kept improving:

v1.0 had simple scraping methods
v2.0 added more selectors
v3.0 used 15 different methods

Like it was genuinely improving alongside me.

What This Means

For Individuals:

New Possibilities

Things you used to think “this needs a programmer” – you can do yourself now.

This isn’t just efficiency gains, it’s:

💡 Ideas can become reality
🚀 No need to depend on others
💰 Save costs and time
📈 Rapid experimentation and improvement

For Entrepreneurs:

Lower Barriers

MVP (Minimum Viable Product) changed from “need to find a programmer” to “can build it yourself over the weekend.”

Want to validate an idea? Just build it and see.

For Everyone:

Mindset Shift

What matters is no longer “can I do this,” but:

Do I want to do this
Can I persist
Am I willing to learn

Skills can be supplemented with AI, but ideas and drive cannot.

Final Thoughts

This little extension might not be perfect, but it proves something:

In the AI era, ordinary people can really build products.

You don’t need:

Elite education
Technical background
Lots of money
Professional team

You only need:

A problem you want to solve
A good AI assistant (like Claude)
Willingness to try
A bit of time

To Those Still Hesitating

If you have an idea but think “I can’t code, I can’t do this”:

Just try.

What’s the worst that could happen? Waste a few hours?

What’s the best? You might build a tool that changes your life.

AI is ready. Are you?
