# Find Missing Pokémon Cards with an AI Collection Tracker Quickchat published a tutorial for building a Pokémon collection tracker with a [Quickchat AI Agent called Binder Check](). It reads a Google Sheet of the cards you own and compares it with TCGdex catalogue records to show which cards you're missing. The walkthrough starts with a small test case: two Japanese Gengar holo cards, where SM4S-022 is in the sample inventory and S10a-023 isn't. You connect Google Sheets, which creates a spreadsheet with one row per exact printing (card ID, set, local number, language, variant, quantity). Then you add two read-only API Actions that point at the public TCGdex REST API, which needs no API key. One searches by printed name in a chosen language, and the other pulls the full record for a single card ID. Each card ID in the results links back to its source. From there you add a conflicting language row and reuse the same setup for your own collecting goals. Before you connect an inventory, the tutorial has you switch Widget & Embed access off and set Chat Page Access to Nobody, so only the signed-in AI Preview can reach your sheet. You can also have ChatGPT or Claude set up the Actions and Main Prompt through Quickchat's account connection. Google consent and those two access settings stay manual. Google Sheets uses drive.file access, so the Agent can only read the spreadsheet the connection creates. To use an existing binder file, copy your rows into the new one. Tests use AI credits.
