Ruby — 1 Year (Live Flip-Profit Assistant for Whatnot)
❌ Not compatible with: iPhone, Android, iPad, or any phone/tablet — mobile browsers cannot run Chrome extensions.
Windows version in development. After purchase you receive the download and a license key by email — paste the key into Ruby to unlock. Please confirm compatibility before purchasing.
One year of Ruby for $100 — no monthly bills, no auto-renew. (Prefer to pay monthly? Ruby is $30/mo instead — but you never pay both.) Launch price ends July 31.
Know your flip profit before you bid.
Ruby watches your Whatnot stream and does the reseller math in real time — all-in cost vs. real resale value — then calls it BUY, THIN, or PASS before the timer hits zero. Runs on your Mac. Nothing is uploaded.
Built for coin buyers & sellers
- Real SOLD prices — coins priced off real eBay SOLD comps (what they actually sell for right now), not asking prices. Silver Eagles, Morgans, Peace dollars, key dates, bullion.
- Graded values — NGC/PCGS MS & PR grades priced to the correct tier; add a free PriceCharting key for the cleanest graded and world-coin reads.
- Photo Match (1:1) — compares the live video frame to the comp photos so you know the price is for the exact coin, not a lookalike.
- Listen to Seller (beta) — optionally uses the stream’s audio (never your mic) to catch what the seller calls the coin.
- Accurate-or-nothing — shows a price only when it can confirm the coin; if it can’t, it says “no price” instead of guessing.
- Works for cards and collectibles too — Pokémon, sports, slabs, Funko — all off real eBay SOLD comps.
What Ruby does on every lot
- IDs whatever’s on camera and pulls the real resale value
- GREEN ↑ / RED ↓ profit calls with Whatnot fees, shipping, and your profit floor already baked in
- Your ceiling bid on every lot — auction fever’s kill switch
- Shows its evidence: the matched item, photo, source, and confidence on every call
- Session P&L with CSV export
- 100% read-only — never bids or automates

Requirements: Mac + Google Chrome. Optional free eBay / PriceCharting keys make pricing faster and sturdier — but with no keys, Ruby stays free and reads eBay SOLD comps on its own. Not affiliated with Whatnot or eBay. Estimates are decision support, not guarantees.
14-day money-back guarantee on this digital product. Your license is valid for one year from activation. Profit figures are estimates based on market data, not guarantees. Ruby never places bids — you stay in control.
