Questions & Answers

As answered by people managing Slabline and Diffee.

How would you describe the primary audience of your product?

Slabline's answer

Collectors who own graded cards (slabs) and want to know what their collection is really worth: from people with a handful of PSA 10s to serious collectors with hundreds of slabs. Also collectors deciding whether to grade raw cards, and anyone who wants their collection documented for insurance.

What makes your product unique?

Slabline's answer

Every value is tied to the real sales behind it. Slabline shows a card's price at every grade (PSA, BGS, SGC and CGC) along with the dated recorded sales it came from, so you can see why a card is worth what it's worth. Then it goes beyond a price tracker: it manages your whole collection like a portfolio, predicts a raw card's grade from a photo before you pay to grade it, and scores how well your collection is protected, with insurance-ready records.

Why should a person choose your product over its competitors?

Slabline's answer

Most card apps give you one number. Slabline gives you the number, the sales behind it, and what to do next: which grader pays most for your card, whether grading a raw card is worth the fee, and whether your collection is properly insured. It covers sports cards and Pokémon/TCG across four grading companies, works on web, iPhone and Android, and you can start free without an account.

What's the story behind your product?

Slabline's answer

Slabline is built by Hobby Smart Case, a company of collectors that makes protection gear for card collections. We kept hearing the same two questions: "what is my collection actually worth?" and "am I protected if something happens to it?" Slabline is the software answer to both: live values from real sales, and a single score for how well your collection is protected.

Which are the primary technologies used for building your product?

Slabline's answer

  • Computer vision — identifies a card from a phone photo by matching it against an image index of our 1.57M-card catalogue
  • AI grading models — read centering, corners, edges and surface to predict a raw card's likely grade
  • Sales data pipeline — ingests recorded sales from eBay and the major auction houses every night and re-prices each card by grade
  • Web, iOS and Android apps — one TypeScript/React codebase across all three
  • MCP server and ChatGPT app — so AI assistants can look up card values directly
