Questions & Answers

As answered by people managing https://open-gpt.app/ and CardGrade.

What makes your product unique?

CardGrade's answer:

CardGrade combines a 47-point computer-vision inspection with predicted PSA, BGS, and CGC outcomes in about 60 seconds. Each report includes sub-scores, confidence, centering measurements, and a market-value estimate when available, so collectors can pre-screen cards before paying to submit them for professional grading. CardGrade is an independent prediction tool, not an official grading service.

What's the story behind your product?

CardGrade's answer:

CardGrade grew from TCG Treasury LLC’s focus on practical tools for trading-card collectors. The product was created to make pre-submission condition review faster and more consistent: upload front and back photos, receive a structured AI inspection, and decide which cards are worth sending to a professional grader.

Why should a person choose your product over its competitors?

CardGrade's answer:

Choose CardGrade when you want a fast, repeatable pre-screening workflow across Pokémon, sports cards, Magic: The Gathering, Yu-Gi-Oh!, One Piece, and other collectible cards. It combines front-and-back image analysis, four-pillar sub-scores, cross-company grade predictions, collection history, and optional market-value context in one workflow. Results are estimates, so they help prioritize submissions rather than replace professional grading.

How would you describe the primary audience of your product?

CardGrade's answer:

CardGrade is built for collectors, card shops, dealers, and grading-prep workflows. It is useful for anyone who wants to identify centering, corner, edge, and surface issues before spending money and time on professional grading submissions.

Which are the primary technologies used for building your product?

CardGrade's answer:

CardGrade uses TypeScript-based web, mobile, and browser-extension clients, with React/Next.js and React Native/Expo surfaces backed by computer-vision and AI grading services. The system combines image capture, structured condition analysis, grade-prediction logic, account and collection workflows, and store-connected billing.

Who are some of the biggest customers of your product?

CardGrade's answer:

  • Individual collectors and hobbyists
  • Card shops, dealers, and grading-prep workflows

Customer names are not publicly disclosed.
