FAQ
Frequently asked by fellow collectors.
01 What is GrailHound?
GrailHound is a marketplace alert tool for collectors and resellers. You set up trackers for keywords and we alert you when they show up on one of your marketplaces. Our goal is to make sure that you are the first to the listing.
02 Why would I use GrailHound versus searching directly?
Hidden gems surface when you least expect them, and no one can search every marketplace all day. GrailHound keeps a constant watch, so you save the time and still catch your grails.
03 How often do you search?
The free plan searches up to 3 marketplaces every 30 minutes. Paid plans go up to 10 marketplaces and can scan every 2 minutes.
04 How are alerts sent?
Email, push notifications from the GrailHound app, or notifications in your browser. There are also webhooks for more technical use cases.
05 Am I notified of every single new listing?
Yes, if you want to be. You can also filter: set a price range, include or exclude keywords, or write an AI prompt that checks each listing before the alert goes out.
06 Do you buy or bid for me?
No. GrailHound is a monitoring and alerting tool.
