A competitor undercut you six days ago, and you still do not know: Seller Center only shows your own shop. SoldCount reads the public sold counter on any TikTok Shop listing, yours or a rival's, about every 6 hours, and tells you the moment one moves: a price cut, a sales jump, out of stock. Every number shows how sure it is and how old it is, and where history is thin it says so. Free to start, no card, read-only. It also connects to Claude.
