CartHawk

CartHawk is a mobile + web app (with a browser extension) that watches the exact items you intend to buy and tells you where they’re cheapest right now. Instead of generic “deal feeds,” users paste a product URL (or import from Amazon/Walmart/Target carts) and CartHawk matches the same SKU/UPC across major retailers and reputable marketplaces, factoring shipping, taxes, coupons, and membership pricing. It alerts you when the all-in price drops below your threshold and shows a clean breakdown of why. It also flags common traps: third‑party sellers with bad ratings, inflated “was” prices, and bait-and-switch variants. This is a combination traditional + AI app: traditional for tracking and calculations, AI for product matching, variant normalization, and scammy listing detection. Monetization is realistic: affiliate revenue where allowed, plus a small subscription for unlimited tracking and premium alerts.
