How Trutinex comparisons work, where Amazon US prices come from, and how we handle ratings, cookies, and affiliation.
Using Trutinex
What is Trutinex?
Trutinex is a tech comparison site. We help you compare smartphones, laptops, gaming PCs, graphics cards, and processors using live Amazon US catalog data (price, popularity, and ratings when Amazon provides them).
Which products can I compare?
Five categories: smartphones, laptops, gaming PCs, graphics cards (GPUs), and processors (CPUs). A comparison is always locked to one category: you cannot mix a phone with a GPU.
How do I start a comparison?
Search Amazon US from the header, open a category page, or tap Compare on a product card. Add 2 to 4 products, then open the comparer to see price, popularity, and ratings side by side.
Comparison rules
Why can I only compare products in the same category?
A phone and a graphics card are not comparable on the same criteria. Locking the comparison to one category keeps the verdict useful: price, popularity, and Amazon ratings when they exist.
How many products can I compare at once?
Up to four products, in the same category. That is enough to shortlist options without turning the table into noise.
Where is my comparison list saved?
Your comparison is stored locally in your browser (local storage). It is not sent to our servers. Clearing site data or using another device starts a new list.
Amazon, prices, and ratings
Where do prices come from?
Live Amazon US listings (amazon.com) at query time, in USD. Price and availability can change at any time. Always confirm the offer on the Amazon product page before buying.
Why are prices in USD instead of euros?
The catalog is Amazon US. Checkout, tax, and shipping are handled by Amazon.com, not by Trutinex. Whether Amazon ships to your country depends on the offer and the seller.
Does Trutinex invent Amazon star ratings?
No. We never invent Amazon ratings. When Amazon provides customer reviews, we show them. When ratings are missing, the comparison uses other catalog signals such as price and Amazon sales rank. We do not fabricate review scores.
Does Trutinex sell the products?
No. Trutinex is a comparison site. Purchases, payment, shipping, and returns are handled on Amazon.com.
Do you earn a commission if I buy on Amazon?
Yes. Trutinex is an Amazon Associate. Qualifying purchases through our links may earn a commission, at no extra cost to you.
