Set up the extension on your phone
Add CompGenies in one tap from the Chrome Web Store, then point it at any card in a live auction — it identifies the card and shows real eBay sold prices, the value range, and recent sales so you know what to bid.
How CompGenies works
One small extension for your browser — computer, iPhone, or Android. Four steps.
- 1
Install the extension
Add CompGenies to Chrome on your computer, Orion on your iPhone, or Kiwi on your Android. One extension, every device.
Step-by-step guides with screenshots are on the install page.
- 2
Open a live auction
Go to a Whatnot, eBay Live, or TikTok Live stream. The CompGenies panel appears in the bottom corner of the video — no screen sharing, nothing extra to set up.
Minimize it to a slim strip when you want it out of the way.
- 3
Read the card on screen
When a card comes up, press Next unique card. CompGenies reads the card straight from the video and identifies it — each card is read once, never twice.
Use Pick area to aim at one spot on screen, and Reset area to go back to the full view.
- 4
Read the value, then bid
You get the card's current value, a low-to-high range, and recent eBay sold prices — so you know your walk-away number before the bidding gets loud.
Every card you've read is saved to your history so you can revisit it later.
What you actually see
The card CompGenies read, its current value, the low–high range, and the recent sold prices behind it. One click opens the full eBay sold search if you want to dig deeper.

What it looks like on your phone
The CompGenies panel sits in the bottom corner of the live stream. Tap Next unique card and it reads the card on screen, then shows the real eBay sold price — without covering the auction.
Full step-by-step install guides with screenshots for iPhone (Orion) and Android (Kiwi) are on the install page.
How to use the Collection tracker
Photo to portfolio in four steps
Tap through the walkthrough to see exactly what happens after you add a card — on your phone or on your computer.
1 · Add a card photo
On your phone, tap Add card and take a picture of the front of the card. On a computer, drop in a photo you already have. Raw cards and graded slabs both work.
