From screenshot to cash prizes in 5 simple steps. No complicated setup, no manual card entry.
Open Coin Master, navigate to your card collection, and take screenshots of each album page. That's it — no zooming, no cropping needed. SwapDeck handles messy screenshots, partial pages, and any screen size.
Works with any device. Any screenshot.
Upload your screenshots and our Vision Language Model goes to work. It identifies every card by name, detects star ratings, counts duplicates, and flags what you're missing — with 97%+ accuracy.
Your screenshots are processed in real-time and never stored on our servers.
SwapDeck's smart matching algorithm scans every trader's inventory and finds mutual matches — people who have what you need AND need what you have. No more one-sided offers.
Match quality scores help you pick the best trades first.
Complete trades, rate your partners, and earn tickets with every transaction. The more you trade, the higher you climb on the leaderboard and the more chances you get to win.
Build your reputation and become a trusted member of the community.
