Frequently Asked Questions

Comp Buddy is the live sales data platform for collectibles. We record real sales from live streams the moment the hammer drops and turn them into searchable prices, market trends, and instant comps. You can use it three ways: the web dashboard with the full live sales database, the Chrome extension that comps while you shop, and the Comp Buddy Live iOS app.

Yes — Comp Buddy Live is on the App Store for iPhone. Screenshot any card while you watch a live stream on Whatnot, TikTok Live, eBay Live, and more, and get instant comps without leaving the auction. You can also search sold prices, follow market trends, and manage your watchlist from your phone. Download it here.

Free gets you the community dashboard and full search of the live sales database — no account required — plus each day's top sales. Pro ($15/month or $150/year with a 7-day free trial) unlocks comping any card while you watch a livestream, Market Trends, the real-time Live Sales Feed, Watchlist alerts, Players & Items sales history, top sales across weekly/monthly/yearly windows, and the full toolkit on every surface. See pricing for the side-by-side.

While you watch a live stream, capture the card on screen — on iPhone, just save a screenshot — and Comp Buddy identifies it and pulls recent sold prices across grading tiers in seconds, so you know the value before the countdown hits zero. It works on Whatnot, TikTok Live, eBay Live, and more, and every comp is grounded in sales we recorded live.

Sports cards and Pokémon are the heart of the database today, alongside other TCGs, sealed product, and more collectibles — and it grows with every stream we record. If it sells live, we aim to capture it.

Yes. The sales database is built from publicly visible live-stream sales — item, price, and seller handle — and your personal data stays yours: we don't sell it or track your browsing. Screenshots and video frames you comp are processed in real time and never stored. See our privacy policy for details.

No — the dashboard and sales search are open to everyone, no account needed. A free account adds things like recording sales, and Pro (7-day free trial) unlocks livestream comping, trends, the live feed, watchlist alerts, and player history. Start your trial here.
