Smart Product Comparator

🛒 Product Comparator – Make Smarter Buying Decisions with AI

Do you ever get stuck endlessly comparing two or more products online, unsure which one offers better value or features? What if you had a smart shopping assistant that could instantly read any product page, summarize its details, compare it with saved alternatives, and even tell you which one is a better buy?

Product Comparator is your intelligent, AI-powered companion that makes online shopping smarter, easier, and more informed. Whether you're choosing between two similar products on different websites or exploring a whole lineup of tech gadgets, tools, clothes, or home appliances — this extension gives you clarity, context, and confidence right in your browser.

💡 What is Product Comparator?
Product Comparator is a browser extension for Microsoft Edge (also works on Chrome) that uses cutting-edge AI to extract key product information from any product page — like a digital shopping assistant that never misses a detail.

It shows you:

🧾 A clean, accurate summary of the product

⭐ A list of key features

💰 The price

🧠 An AI opinion on whether it’s worth buying

🆚 A side-by-side comparison with previously saved products

With a simple click, you can activate the extension on a product page. The AI processes the visible content, extracts relevant details, and offers an intelligent summary and recommendation. If you've saved another product earlier, it will show you how the two stack up — including which one the AI thinks is the better purchase.

🚀 Key Features
📃 Product Summarization
No need to scroll through long, cluttered product pages. Product Comparator summarizes the product description, highlights what it does, what makes it unique, and who it's for.

🎯 Key Feature Extraction
From technical specs to usability highlights, the extension extracts the product’s main features using AI. You’ll see clear bullet points like:

Battery life: 10 hours

Display: 1080p, 60Hz, 6.5”

Waterproof: Yes (IP68)

This helps you evaluate specs without reading through paragraphs of marketing fluff.

💵 Real-Time Price Analysis
The extension scans the page to find the product’s listed price and displays it clearly in your popup. If there are discounts, bundle deals, or savings applied, those will be detected and noted by the AI.

✅ AI-Powered “Buy or Not” Recommendation
Is this product a smart choice? Let the AI evaluate it. Using a combination of summary, price, and features, the assistant gives an opinion like:

“✅ Based on its strong feature set, reasonable price point, and user reviews, this product is a good buy for most users.”

It’s like having a trusted expert giving you a quick thumbs-up or warning before purchase.

💾 Save Products for Later Comparison
Click the Save Product button and store product details locally. When you’re on a new product page, the extension will detect previously saved products and give you the option to compare.

🔁 Compare Two or More Products Side-by-Side
If you’ve saved other items before, Product Comparator shows a tabular comparison:

Feature Current Product Saved Product
Price $49.99 $39.99
Waterproof Yes No
Warranty 2 Years 1 Year
It even summarizes which product is a better deal based on your preferences.

🧠 AI Opinion on Which One is Better
After comparing the two, the AI will say something like:

“📢 Between the two, Product A offers more value for the price due to its better build quality and warranty. We recommend Product A.”

No more guessing or opening multiple tabs to cross-reference specs!

🔒 Privacy-First by Design
Product Comparator works fully locally in your browser. No product data is sent to external servers unless used for summarization by OpenAI or a similar LLM provider. Saved products are stored on your device using chrome.storage.local or edge.storage.local. Your browsing history, personal data, or shopping behavior are never tracked or monetized.

You remain in control of your data.
