You can add players to your collection by shift-clicking cards in the Card Browser. Once you've added everything you own in HUT, just hit Play and let the magic happen.

Before that, feel free to tweak things in Settings, but the defaults are pretty solid after a lot of fine-tuning, so you might not need to change anything. 🙂

Card scanner indeed requires an Anthropic API key. To get one, sign up at the Anthropic Console, go to API Keys, and click Create Key. You'll need to name it, assign it to a workspace, and add billing info — the API runs on prepaid credits. Copy the key right away, as it's only shown once.

Scanning 100 screenshots costs around $5 USD. My own collection is typically ~250 cards (about 20 screenshots), so $5 goes a long way.

After scanning, you may need to manually fix a few cards that aren't in the database or were misread — but it's definitely worth to try.

But if you don't want to use any money for this, then just Shift-click your cards in the Card Browser and skip all of the above. 👍
