Kept overpaying on Amazon so I did something about it

I’m a solo builder and I’ve been working on a Chrome extension called Lowly in my spare time. It started as a personal frustration. I kept buying things on Amazon without realizing a cheaper, nearly identical product was sitting right below it on the same page.

What it does:

When you’re on an Amazon product page, it scans the related products in the background, ranks them by similarity and price, and shows you cheaper alternatives in a popup. No searching, no extra tabs.

What I’ve built into it so far:

Unit Price Calculator: breaks down price-per-unit automatically so you’re comparing real value, not just total price

Wishlist with price history chart: save products and track how the price moves over time

Similarity Filter: a slider to control how closely alternatives need to match your product

Works across 18 Amazon domains: same extension whether you’re on .com, .co.uk, .de and so on
No data, no sign-up: runs entirely in your browser, nothing leaves your device

The honest part:

It’s working well but I’m still actively improving it. The matching algorithm is the part I’ve spent the most time on. Getting it to understand that a 48-pack of toilet paper and a 12-pack are the same product just different quantities took more work than expected.

Would love feedback from other builders. What would make this genuinely useful to you?

I got tired of overpaying on Amazon so I started building a free extension to fix it - would you use this?

Hello everyone!

I kept losing money on Amazon by grabbing the first listing instead of the better-priced one right below it. After opening too many tabs I got fed up and started building a free Chrome extension to fix it, it’s called Lowly. Still actively working on it and would love to know if this is something you’d actually use.

What it does:

When you’re on an Amazon product page, it scans the related products, ranks them by similarity and price, and shows you cheaper alternatives in a popup.

A few things I’ve built into it so far:

Unit Price Calculator: automatically breaks down price-per-unit (per roll, per ounce, per pack) so you’re comparing real value, not just sticker price

Wishlist with price tracking: save products and see a price history chart over time, so you know when to pull the trigger

Similarity Filter: a slider to control how closely alternatives need to match

No data, no sign-up: runs entirely in your browser, nothing leaves your device

Would you use something like this? And if so, what would make it a must-have for you? I’m genuinely building this based on feedback so every response actually shapes what gets built next.

I never scrolled past the first Amazon listing and it was costing me money

Ok so this is embarrassing but I'm posting anyway because maybe someone else is having the same problem.

I was buying AA batteries a few days ago. Just grabbed the first Duracell pack that came up, added it to my cart. My partner happened to scroll down and goes "wait, there's a 48 pack for basically the same price as your 20 pack right here."

I would have bought the smaller pack without even noticing.

That got me actually looking at the related products section on Amazon listings. Turns out Amazon shows a bunch of similar products further down the page but they are buried in those carousels nobody really scrolls through. Once I started actually checking them I found better value options on almost everything I buy regularly.

The problem is doing it by hand is kind of a pain. You have to scroll down, find the carousels, click through, check the per unit math. I got lazy about it pretty fast.

So I created a free Chrome extension "Lowly" that automates it which helped, but even just doing it manually is worth it.

The savings are not massive every time but on things I buy regularly it has added up.

Anyone else actually checking those related product carousels or am I late to this?
