Live Card Comps Companion Start scanner

Know what the card on stream is, and what it is listing for, in about a second.

Live Card Comps Companion watches the browser tab you share of a live card auction, recognises the Pokémon card the streamer is holding up, and shows a labelled, time-stamped price picture in a small always-on-top window: the card's identity, variant and language with an explicit confidence, TCGplayer market and lowest listing per condition, eBay asking prices, where each number came from and how old it is, and a bid ceiling worked out from your own margin and shipping.

Built on three promises

Your stream never leaves your browser

Frames are analysed in memory on your machine and are never written to disk, logs or analytics. You share one tab or window, never your whole display. Nothing is uploaded unless you turn on the optional cloud fallback, and then only a tightly cropped card image. How frames are handled.

Sold and asking prices are never merged

Market prices and asking prices are different things, so they are shown apart and never averaged. Every number carries its source, condition, listing count and an "updated N ago" stamp.

Confidence, variant and language, stated

The result names the exact printing from the catalogue, its language and its finish, with a confidence percentage. Below the threshold you see "tap to confirm" or nothing, never a guess dressed up as certainty. One tap corrects a wrong card.

How it works

  1. Open the live auction in your browser and press Start scanner. Your browser asks which tab or window to share.
  2. The scanner finds the card in the video, reads it and matches it against the catalogue on your device.
  3. The result window shows identity, confidence, prices with source and freshness, and your bid ceiling.

Works alongside the platforms you already use

Works alongside Whatnot, Twitch, YouTube and eBay Live streams playing in your browser. It only reads your own screen: it never connects to a streaming platform, changes a page or places a bid. Not affiliated with or endorsed by any platform or marketplace.
