A browser extension for Chrome and Firefox (desktop) for watching Yu-Gi-Oh! videos and streams. Hover a card in a YouTube or Twitch video and a larger picture of it appears, with its name, type, stats and text.
The card details can be in French, German, Italian, Spanish or Portuguese, with the official card text where one exists: choose the language in the popup, or leave it on Automatic to follow your browser. The rest of DuelSight is in English.
DuelSight is an unofficial fan project, not affiliated with or endorsed by Konami. 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. Card names and texts in other languages from Yugipedia, under CC BY-SA 4.0; those card details files are offered under that license too.
It is aimed at Master Duel, Dueling Book and paper tables, with the camera above the table. Master Duel and Dueling Book are measured and promised; paper is supported but not promised. Results vary by video; see docs/accuracy.md.
- Chrome: install DuelSight from the Chrome Web Store.
- Firefox (148 or later, on a computer; not Firefox for Android): install it from Firefox Add-ons.
Then open a Yu-Gi-Oh! video on YouTube or Twitch and rest the pointer on a card.
If your Chrome can't use the store, install from a release zip instead: see docs/install-from-zip.md. Firefox has no zip route: it installs add-ons that Mozilla has signed, so use Firefox Add-ons.
- No accounts, analytics, telemetry or advertising.
- Video frames are never uploaded. They are analyzed inside your browser, in memory, and not saved.
- The extension requests one host, DuelSight's card CDN, for a small settings file, card pictures and a card details file, without cookies, an account ID or the address of the page you watch.
Details: PRIVACY.md and docs/permissions.md.
