CableCart

CableCart is a mobile app + browser extension that checks whether a cable or adapter will actually work with your exact devices before you buy. You select (or scan) your phone/laptop/monitor/dock models, then paste a product link (Amazon, Best Buy, AliExpress, etc.). The app flags common gotchas: USB-C “charge-only” vs data, USB 2.0 vs 3.x speeds, Thunderbolt compatibility, PD wattage limits, HDMI versions, alt-mode requirements, and whether your device supports video over USB-C at all. It also warns about misleading listings and recommends safer alternatives with verified specs. This is a traditional app with a small AI component used to extract specs from messy product pages and images, but it relies on a curated rules engine and device capability database for accuracy.
