What CardChain AI does in ChatGPT
The CardChain AI plugin brings trading card market data into ChatGPT. You can identify a card from a photo or by searching, then see its current price along with a 30-day price history. It is aimed at collectors who want numbers in front of them before they buy, sell or grade.
It also shows population reports across grading companies, which tell you how many copies of a card have received each grade. There is an ROI analysis that sets the cost of grading against expected values, so you can work through whether sending a card in makes sense for you.
Beyond single cards, you can see the value of your whole collection, spot the biggest movers in it and check how a player's season is affecting demand for their cards. You can also browse cards listed for sale on the CardChain AI marketplace.
