01 How it works

1

Install the extension

Drop the unpacked folder into Chrome. We'll DM you the build the day your beta slot opens.

2

Open any Whatnot stream

Slabbr lives on whatnot.com. No setup per stream — it's there when you need it.

3

Press Shift+S

Card, set, price, condition ladder, and the live bid tracker — all under 5 seconds. Decide before the timer hits zero.

02 What you get

Real-time card ID

Ximilar's TCG vision API identifies the card from a single video frame. 94.1% accuracy across 238 scans on live streams.

Live market price

Pulls from JustTCG — TCGPlayer-backed pricing for NM, LP, MP, HP, and DM. Click any condition to flip the headline.

Live bid tracker

Watches the auction's current bid and computes your margin in real time. Green when there's room. Orange when it's close. Red when you're underwater.

Confidence signal

HIGH, MEDIUM, LOW — driven by Ximilar's distance scores, retuned on real data. When Slabbr's unsure, you'll know.

Candidate swap

Wrong set? Click any of the 4 alternates — prices update instantly from cache. No second API call, no waiting.

Copy log row

One click writes a 22-column TSV row. Paste straight into the stress-test sheet. Every scan auditable.

04 FAQ

What is Slabbr exactly?

A Chrome extension that runs on whatnot.com. During any live auction, you press Shift+S and Slabbr identifies the card on the stream and shows the live market price — plus a real-time profit signal against the current bid. Built for Pokémon TCG, English language, in beta.

What will it cost?

Free for your first 30 days (15 scans/day, no card). After that, the free tier drops to 8 scans/day and paid plans start at $9.99/month (Hunter, 75 scans/day). See the full pricing breakdown. Cancel anytime — this isn't a venture play, it's a tool the founder uses every day.

What cards does it work with?

Pokémon TCG, English. Other TCGs (Magic, Lorcana, One Piece, Sports) are on the roadmap but not in the beta. JustTCG indexes most modern + vintage sets; very-new sets (within a few weeks of release) may not have prices yet — Slabbr shows "no pricing data" rather than guessing.

Is my data safe?

The extension stores API tokens in chrome.storage.local on your machine — never sent to a Slabbr server. The only data leaving your browser is the video frame for the scan, sent directly to the identification API. No telemetry, no tracking pixels, no analytics in the extension itself.

Why charge at all?

Every scan costs real money — vision API + pricing API calls add up. The free tier covers casual use; the paid tiers cover heavier users and keep the lights on. Pricing is set to hit break-even at ~9 paying users at the $9.99 tier. No VC, no growth-at-all-costs nonsense.

Can I cancel anytime?

Yes. Manage your subscription from the Stripe customer portal — link is in the extension popup once you're paid. You keep access through the end of your billing period, then drop back to the free tier.

How accurate is it?

94.1% ID accuracy on 238 real-world Whatnot scans. ~100% price accuracy on cards we have data for (~82% of correctly-ID'd English cards). The overlay shows a HIGH / MEDIUM / LOW confidence label on every scan so you know when to trust it.
