Chrome Extension Idea: Amazon Review Summarizer – Anders Amlie, Juno Kim
Problem Statement
Since online goods are inherently harder to judge than when in-person shopping, reviews from actual people who bought the product are extremely important. Still, Amazon places these reviews at the absolute bottom of their long, clunky product pages. These reviews are both hard to navigate to and digest: they’re long, un-proofread pieces of text – this extension solves both by offering a cohesive pros and cons summary of a product in the click of a button.
Target Audience
Online shoppers
People doing quick product comparisons
Mobile-first or accessibility-focused users
Tech-savvy consumers looking for faster decision-making
Description
When on an Amazon product page, the extension scrapes the page of reviews, sends the text to GPT, and returns a clean, easy-to-read summary highlighting the most common pros and cons of the product. Results are shown in a popup or sidebar UI, triggered by clicking the extension icon.

Notes Challenge: Avoid being blocked by rate-limiting if scraping too many reviews
Add-On: would be cool to enable dialogue with the AI summarizer to query it about specifics of the product, like if age-appropriateness or durability are mentioned in reviews, for example
Consideration: Could be extended to other review-heavy platforms like Yelp, eBay, or BestBuy later on
UI Ideas: Use a minimal sidebar, tooltip, or bottom card for the summary output. Match Amazon’s color scheme for seamless UX
