Inspiration

We were frustrated by how much time online shopping wastes—bouncing across multiple sites, comparing prices, reading questionable reviews, and re-entering payment details every time. We wanted a seamless way to shop smarter and faster.

What it does

BuyScout is an AI shopping agent that:

Takes a product photo or description as input.

Runs OSINT searches across trusted e-commerce and brand sites.

Compares prices, reviews, and availability, then ranks the best options.

Auto-fills checkout for free users.

Offers one-click AI-powered payments with a monthly bill for subscribers.

How we built it

Used computer vision + NLP to extract product details from photos/descriptions.

Built an OSINT search + scraper pipeline to collect structured product data.

Designed a ranking algorithm based on price, reviews, and availability:
