CompareLens — Product Comparison & Best Price

Smart AI product price comparison tool. Compare specs, prices & ratings across store tabs on Amazon, Daraz, eBay, AliExpress & more.

CompareLens AI is the ultimate smart product comparison extension for online shoppers. Whether you're comparing smartphones, laptops, appliances, headphones, or any product across multiple online stores — CompareLens AI gives you a real-time, side-by-side spec matrix and an AI-powered purchase recommendation so you can make confident, informed buying decisions without switching tabs endlessly. 🛒 WHAT IS COMPARELENS AI? CompareLens AI is a Chrome side panel extension that transforms the way you shop online. Instead of opening ten tabs and trying to manually compare RAM, battery, camera specs, and prices in your head — CompareLens lets you scan any product page with one click. It extracts the product name, price, ratings, images, brand, and full technical specifications, then stores them in a clean comparison matrix directly in your browser sidebar. When you've added two or more products, you can open a full-screen side-by-side comparison table instantly — and let the AI analyze the differences and recommend the best pick based on your priority (value, performance, ratings, or balanced). 🔍 POWERFUL PRODUCT SCANNING ACROSS MAJOR PLATFORMS: CompareLens AI works across all major e-commerce platforms and product pages: • Amazon — Extract product titles, ASINs, prices, ratings, review counts, and full spec tables automatically. • Daraz — Scan product listings on Daraz.pk and Daraz.lk to grab specs, prices, and ratings. • eBay — Extract listings, price comparisons, and product details across eBay markets. • AliExpress & Alibaba — Compare Chinese marketplace products with local store alternatives. • Flipkart — Extract product ratings, tech specs, and comparison points from Flipkart listings. • Any Schema.org Product Page — Works on any store or website that uses standard structured product data. 📊 SIDE-BY-SIDE SPEC COMPARISON TABLE: Once you've scanned your products, open the full-screen Comparison Matrix to see every spec side by side: • Price comparison with lowest-price highlighting — see exactly which product offers the best deal. • Technical spec rows auto-ranked by importance — RAM, Storage, Processor, Camera, Battery, Display, OS, Charging, Weight, and more are shown first. • Smart spec ordering — products with the most filled-in data appear at the top, sparse rows fall to the bottom automatically. • Top Spec badges — the product winning each spec row is highlighted in green. • Sticky product headers — product thumbnails, brand, and store buttons stay visible as you scroll through specs. • Remove any product from the matrix with a single click. 🤖 AI-POWERED PURCHASE DECISION INTELLIGENCE: Stop guessing. Let AI help you decide. The CompareLens AI sidebar panel provides: • Balanced Analysis — A full overview comparing value, performance, and satisfaction scores across all products. • Value Focus — The AI identifies the best value pick and calculates the exact price difference you'd save. • Performance Focus — The AI recommends the highest-spec, best-performance option for power users. • Rating Focus — The AI surfaces the crowd favorite based on verified customer ratings and review count. The AI recommendation panel stays visible on screen at all times while you scroll through the comparison table — so you always have the recommendation in sight. 💾 SAVE & MANAGE COMPARISON LISTS: Don't lose your shortlists. CompareLens AI lets you: • Save any comparison matrix with a custom name (e.g., "Smartphones under $500" or "Gaming Laptops 2024"). • Restore saved lists instantly from your Saved tab — all products, specs, and AI analysis come back. • Manage multiple shortlists — one for phones, one for laptops, one for appliances. • Data is stored securely in your local browser storage — nothing is uploaded to our servers. 🌐 MULTI-STORE CROSS-PLATFORM COMPARISON: The biggest shopping pain point is comparing across stores. CompareLens AI solves this: • Compare an iPhone on Amazon vs. Daraz vs. a local store — side by side. • Find which store offers the same laptop cheaper. • See store source badges on every product so you always know where each price comes from. • Open the original product page from within the comparison table with one click. 🔎 SPEC EXTRACTION ENGINE: CompareLens AI uses an intelligent specification extraction engine that: • Auto-detects and normalizes spec labels across different stores (e.g., "RAM" vs "Memory" vs "Working Memory"). • Normalizes brands, models, and spec values so comparisons are clean and readable. • Extracts from structured product tables, bullet lists, and key-value spec sections. • Works on page load automatically — no manual copy-paste required. 📱 PERFECT FOR COMPARING: • Smartphones & Mobile Phones (RAM, storage, battery, camera MP, fast charging, display) • Laptops & Notebooks (processor, RAM, SSD, display, weight, battery life, GPU) • Tablets (chipset, display resolution, stylus support, battery) • Smartwatches & Wearables (health sensors, battery, connectivity) • Home Appliances (power, capacity, energy rating, features) • Audio & Headphones (battery life, driver size, ANC, codec support) • Gaming Peripherals (DPI, switch type, response time, RGB) 🔒 PRIVACY-FIRST DESIGN: Your shopping data belongs to you. CompareLens AI is designed with privacy as a foundation: • No account or registration required — use it immediately. • Comparison data is stored exclusively in your local browser storage (chrome.storage.local). • No browsing history is logged or transmitted. • No user profiles are created. • Product data is only extracted from the page when you actively trigger a scan. • All AI analysis requests are sent over HTTPS to Toolscase secure API servers and are not stored. 🚀 HOW TO USE COMPARELENS AI: 1.
