Product comparison tool
Compare up to four products on your own list of specs and get a score for each.
About this tool
Quick answer: The product comparison tool puts up to four products side by side with their current Amazon prices, lets you type in the specs that matter (battery life, power, weight and so on), and turns your numbers and priorities into a score out of 100 for each product. Templates are included.
How to use it
- Add up to four products by pasting a link or searching current deals.
- Pick a template for your product type, or add your own rows.
- Type each product's numbers for the specs you care about.
- For each row, choose whether higher or lower is better and how much it matters from 0 to 5.
- Read the scores, or download the table as a CSV.
Example: two power banks
| Product A | $25, 10,000 mAh |
|---|---|
| Product B | $40, 20,000 mAh |
| Price matters | 3 (lower is better) |
| Capacity matters | 4 (higher is better) |
| Score A | 43 |
| Score B | 57 |
A is cheaper (3 points of 7) and B has more capacity (4 points of 7), so B scores higher because you said capacity matters more.

Where to find specs
Use the product page, the box or the maker's website, and prefer the manufacturer's figures. What you type stays in your browser.
Free comparison templates
Choose earbuds, power bank, charger or cable, smartwatch or speaker, then download a blank CSV for Excel or Google Sheets. It holds only the rows you chose, not prices.
Use the score as a guide
The score reflects only your numbers and priorities. Read the buying guide for the product type for what numbers can't show, like fit and comfort.
Frequently asked questions
Is there a free product comparison template?
Yes. Choose a template from the menu and download it as a blank CSV, or fill it in on this page.
How is the score calculated?
For each row, the best number among your products gets full marks and the worst gets zero, reversed for rows where lower is better. The rows are combined using your 0 to 5 importance weights and scaled to 100.
Can I compare more than four products?
Not at once. Four keeps the table readable. Remove one to add another.
Is my data saved?
No. Typed numbers stay in your browser while the page is open. The page address contains only the product IDs.
