Inspiration

ShopScout was inspired by a simple frustration shopping online had become noisy, confusing, and full of misinformation. Between fake reviews, inflated prices, and inconsistent listings, it was hard to know what was truly worth buying. I wanted to create a browser-native AI assistant that could cut through the clutter, summarize real insights, and help users shop confidently without compromising privacy. The goal was to make online shopping smarter, faster, and more transparent, all from within Chrome.

What it does
