Spencer Yang(@spenceryang):I’m a One Piece fan, so we turned @NotionHQ into a trading card vault. For the Notion hackathon in SF, we built Grand Line Vault: a Notion-first One Piece TCG collection OS. You can scan a card into Notion, enrich it automatically, track collections across friends, visualize wishlists / duplicates / set completion, and ask a Slack-connected Notion Agent: “what did I just scan?” “show my OP-01 cards” “simulate a battle between Spencer and Waffle” Notion Workers + Agents make Notion feel less like a doc tool and more like a personal app platform. We open sourced it too. Would you use Notion as the interface for a collector app like this?
