Most shopping tools chase coupons. Dupely tackles trust. Online shopping is full of manipulation: artificial price drops, fake reviews, paid influencers, and sketchy white label sellers reselling the same product at a markup. DupeScore finds identical products for less. Trust This Price flags fake savings using 90 days of price history. Seller badges show you who's actually credible. Now on iOS, Android, and Chrome. Dupely is the trust layer online shopping has been missing.











How does DupeScore actually decide two products are real duplicates versus just similar items, especially when brands deliberately rename or repackage the same thing?
@ezelrikliahcg Great q Ezel! We use multiple signals from the product listing pages for relative similarity. We'll also bake in seller reputability too so even if it's a cheaper deal, you'll know you're still getting a good product too. Thanks for using Dupely! :D

Nice idea. How do you handle cases where 2 listings look identical, but the product quality turns out to be different? Congrats on the launch!
@henry_habib Great q Henry! We factor in return volume and the reviews on both the seller and the product. If there is a history of bad product quality, then it'll impact how we recommend that item even if it's a duplicate. Let us know how we can make Dupely even better!! :D
How does DupeScore actually identify identical products versus just similar ones, and does it factor in shipping costs when showing cheaper alternatives?
@smeyye7eqe Great Q Sumeyye! We use multiple signals from the product listings and determine how similar they are. We'll be able to detect minor variations as well as major differences. The "trust this dupe" section pulls historical track record from the seller and product itself so even if it's a cheaper alternative, you know you're getting a good deal. Thanks for using Dupley! :D

How DupeScore handles products with tiny cosmetic differences but identical manufacturers underneath?
@iamanantgupta This is exactly the use-case DupeScore is built for. We do not lean on branding or the title, so a swapped logo, a different color/variation, or different packaging will not throw it off. It might just adjust the score slightly. We weigh the substance underneath, the product images, specs, and description details, this is how we identify two listings coming off the same line still land as a high match even under different brand names. That is why the score runs 0 to 100 instead of a simple yes or no. A near-identical duplicate listing with only cosmetic differences scores near the top, while genuinely different products fall lower down.
The more people we get using the product the smarter our matching will get. We want the community to tell us when we get it wrong and we look into the results case by case to see what we can tweak
Congrats on the launch. I'd love notifications when a trusted seller starts offering a product I've saved. Is there a feature that exists for this?
@divya_kothari1 Absolutely you can save items you viewed to your favorites and you Dupely will alert you if it drops in price.
We don't have a "follow seller" feature but adding that to the list of ideas to add to product roadmap from this thread!

This is a cool idea. How frequently is the seller trust data refreshed as new reviews and returns come in??
@roopreddy Thanks Roop! We get seller trust data updated within 24 hours of when Amazon publishes their updates. Returns are handled differently from our data provider. For larger, more popular products this doesn't impact as much. For new sellers and new products, this is absolutely game changing to reduce latency between returns and seller profile. Thanks for using Dupely! :D
The Trust This Price flag using 90 days of history is the part I'd actually rely on, since fake "was $X, now $Y" drops are exactly what trips me up. When I'm on an Amazon listing with the Chrome extension, does DupeScore surface the cheaper identical product inline on the page, or do I have to open the app and search for it myself? And does the price history cover third-party marketplace sellers, or only the main buy-box?
@leo404 For the Chrome extension when you find the product you want Dupely to find an alternative listing for it automatically starts running matches in the background if you can find any. Price history covers third-party not just buybox. It's at the ASIN level.
The unfortunately reality is terms like "buy-box" "third-party" seller aren't even in the average consumers vocabulary. Instead of changing the user behavior we just want to make it easier for them to make the right purchasing decision - not an influenced one by "social proof"
