GrailHound
ChatGPT pluginMarketplace alerts
GrailHound scans eBay, Facebook Marketplace, Mercari, Vinted, Grailed and dozens more resale marketplaces around the clock, so you don't have to. We alert you when a new listing matches your search: on your phone, your browser or via email.
Ask ChatGPT what your trackers found today, or describe what you're hunting for and have it set up a tracker. It can run a test search on the marketplaces first, so you see what would match before anything is saved.
