How Ruby Works

How Ruby works

  1. Point at the item on Whatnot. The instant a card or slab hits the screen, Ruby reads it — no typing, no pausing the stream.
  2. Ruby pulls live comps. She checks real listings and TCG market values for that exact item and works out your all-in cost vs. resale.
  3. You get BUY, THIN, or PASS — instantly. Green means flip it for profit. Amber means the margin's thin. Red means walk away. Decided before the timer hits zero.

That's the whole edge: you bid on numbers, not adrenaline. Ruby never places bids — you stay in control.
