Everything you need to know about Comp Buddy.
Comp Buddy is a Chrome extension that lets you look up real eBay listing prices (comps) for items shown on any live shopping stream — Whatnot, Facebook Live, YouTube, TikTok, and more. Think of it as having a pricing expert sitting next to you while you shop.
When you click "Scan Item," the extension captures a single frame from the live stream video and sends it to our AI, which identifies the item — including details like year, brand, set, player, and variant. Then we pull matching active listings from eBay.
Sports cards, Pokémon cards, Funko Pops, sneakers, vintage toys, coins, and more. If it sells on a live stream and eBay, Comp Buddy can comp it.
Yes. Video frames are processed in real-time and never stored. We don't track your browsing, don't sell your data, and only collect your email for account purposes. See our Privacy Policy for full details.
You'll need a free account to use the scanning features. It only takes a few seconds to sign up with your email.
All three plans include unlimited manual searches, eBay comps, and the full overlay experience. The difference is AI scan volume: Starter gives you 200 scans/month, Pro gives you 600, and Elite gives you 1,500. Use them whenever you want — no daily caps.
