What FastMoss does
FastMoss is a TikTok ecosystem data platform: trending products, competitor shops, creator discovery, and a LIVE and video monitor that watches streams in real time, metered by monthly credits that rise with the tier. Its best-known feature is transcribing competitor live scripts so you can see the hooks they use.
It has no Whatnot, eBay Live or Fanatics coverage, and its revenue figures for other shops are estimates.
What Ghost Agent does
Ghost Agent watches a live show as it happens, on your handle or a rival's, and reads chat velocity, room turnover, auction pacing and who just walked in. When momentum breaks it tells you what to do while the show is still savable. It alerts you when a known high spender enters your room, keeps a price book for your category built from what is actually clearing across the platform, and writes the post-show report with three concrete changes for next time.
It covers Whatnot, TikTok Live, eBay Live and Fanatics Live and tracks competitor shows across all of them. It is also the most expensive tool in this set, and it is wasted on a seller who goes live once a month.
