About this extension
DuelSight is an unofficial fan project, not affiliated with or endorsed by Konami.

Hover a card in a Yu-Gi-Oh! video on YouTube or Twitch, and a larger picture of it appears beside it, with its name, type, stats and text.
  • Aimed at Master Duel, Dueling Book and paper tables with the camera above the table. Results vary by video, and it can miss a card or show a wrong one.
  • Rest the pointer on a card in a supported video; nothing to set up per channel. The toolbar switch turns it off everywhere.
  • Choose the card size (70% to 130%) and whether the card's text shows beside its picture, in the toolbar popup.
  • Card names and text in French, German, Italian, Spanish or Portuguese: choose the language in the popup, or follow your browser's (official card texts; English where none exists).
  • No accounts, analytics, telemetry or advertising. Video frames are analyzed inside your browser and never uploaded.
  • Open source (Apache-2.0), built on the cardvision toolkit: https://github.com/ryangswe/riftsight-vision

Yu-Gi-Oh!, its card names and its card art belong to their owners. Card text and images are copyright 4K Media Inc., a subsidiary of Konami Digital Entertainment. Card data from YGOPRODeck.
