About Card Signal
The card research workspace we wanted to use.
Card Signal started with a simple idea: card research should not require a maze of tabs, disconnected tools, and guesswork. We are building one focused place to search cards, compare market context, find official checklists, run the numbers, and organize a collection.
Why we built it
Useful for our own collection, then useful for the hobby.
We wanted a tool that helps answer the questions collectors actually ask: Is this the exact card? What are comparable listings showing? Does the price still make sense after shipping and fees? Is grading worth the cost and risk? Where can I find the official checklist?
Card Signal brings those workflows together while keeping the underlying sources visible. It is designed for sports cards and major trading card games, for newer collectors learning the basics and experienced collectors who want a faster research routine.
For Mr. Kevin
A very good reason to keep moving forward.
Kevin, better known as Mr. Kevin, is paralyzed and is also the best guy. His resilience, personality, and determination bring a lot of heart to this project. This part of Card Signal is in honor of him.

Built in public
Card Signal will keep improving with the hobby.
We are still early. The goal is to keep making the search cleaner, the market context more useful, the collection tools more capable, and every feature easier to understand on a phone or desktop.
