Everything you need to know about StackedUp
What products can I compare?
You can compare any Amazon products by pasting their URLs. Our AI works with electronics, home goods, books, clothing, and virtually any product category available on Amazon.
Is StackedUp free to use?
Yes! You get 10 free searches and comparisons without any signup. After that, create a free account for unlimited access - no payment required, ever.
How accurate are the AI comparisons?
Our AI analyzes real product data, specifications, and customer reviews to provide objective comparisons. While highly accurate, we recommend using our analysis as a starting point for your research.
Can I compare different categories?
For best results, compare products within the same category (e.g., laptops with laptops). Cross-category comparisons may not provide meaningful insights due to different use cases and features.
Why not just use ChatGPT for product comparisons?
ChatGPT relies on outdated training data and can't access current prices, availability, or recent reviews. StackedUp fetches live product data and provides structured comparisons with real-time information.
Do AI tools hallucinate product information?
Yes, AI models often generate incorrect specs, prices, or features when they lack real data. StackedUp eliminates hallucinations by using only verified product information directly from Amazon's database.
