🐶 Sniff It — Find Cheaper Products & Spot Overpriced Stores in One Click

Stop overpaying online. Sniff It is a free price comparison and product-finder extension that quietly checks whether the item you're about to buy is being resold at a huge markup — and shows you visually similar products at fair prices, instantly.

Whether you stumbled onto a slick Shopify store, a no-name dropshipper, an unfamiliar fashion site, or a paid Instagram ad, Sniff It does the homework for you. The moment you land on a product page, it reads the title, price and product image, runs a fast market check against AliExpress, Amazon and direct-from-manufacturer sources, and warns you when you're being charged way more than the product is actually worth. No clicks. No noise. Just smarter shopping when it matters.

✨ NEW: Hover any image, find the product

On any shopping page — product pages, category listings, search results — pause your cursor on a product image for a second and a "Find this product" button slides in. One click pulls up visually similar items on AliExpress and Amazon with thumbnails, prices, and real order counts. Browsing a fashion lookbook? Hover the photo. Scrolling Etsy or a Shopify store? Hover the listing. Sniff It will find the same item — or close cousins — at the best price available online.

🔍 What Sniff It does

• Automatic price check on every product page — compares the store's price against typical market rates and flags inflated listings before you check out.
• Scam-store detection — analyzes the domain, TLD and product category for the signals that usually point to low-quality dropshipping or shady resellers.
• Reverse image search built in — both the new hover-to-find button on shopping pages AND a floating puppy on product pages open a panel of visually matched alternatives.
• Variant aware — pick a different color or size and Sniff It uses the photo you're actually looking at, not the default-color shot.
• Respects real brands — on official stores like nike.com or ray-ban.com, it stays quiet about overpricing (you can't get the genuine item cheaper) but still surfaces similar styles when you want to compare.
• Per-site mute — silence alerts on any store with one click, then manage muted sites from the settings panel.
• Recent sniffs history — every product you've checked is saved with thumbnail, title and price; reopen the page, pull up alternatives, or clear the list whenever you like.
• Multi-currency support — detects the store's currency automatically and converts to your preferred display currency using daily exchange rates.

🛡️ Privacy first — what we don't do

• We don't track your browsing history.
• We don't collect or sell personal data.
• We don't read page content outside of product metadata (title, price, image, currency, domain).
• We don't show ads. Ever.

💸 About affiliate links

Some of the alternative-product links Sniff It surfaces (AliExpress, Amazon) include affiliate codes. If you click through and buy on those sites, we may earn a small commission — at no extra cost to you. The price you pay is unchanged. This is what keeps Sniff It completely free for everyone.

👤 Who it's for

• Shoppers who see a product on an unfamiliar store and want a second opinion before checking out.
• Anyone tired of paying 4× the AliExpress price for the same generic gadget dressed up on a slick Shopify site.
• Gift buyers who want to sanity-check a price in seconds.
• Fashion shoppers who like the look of an item but want to see if there's a similar one for less.
• Bargain hunters, frugal shoppers, and anyone who hates being upsold.

Install Sniff It, keep shopping the way you always do, and let it warn you only when it matters. 🐾
