ShopSmart Pro

About

🛒 ShopSmart Pro makes online shopping faster, clearer, and cheaper. Compare prices across marketplaces, track products, view price history trends, predict prices with AI, and get smart alerts—without leaving the page. Built for real-world shopping and tuned for speed, privacy, and convenience.

I built ShopSmart Pro initially for my own shopping needs, and I'm excited to share it with fellow bargain hunters. Based on user feedback and adoption, I plan to add more features and expand to additional shopping platforms in the near future.
