# MasterGrade

> MasterGrade (mastergrade.ai) is an AI-powered trading card grading and collection platform. Upload photos of a card and MasterGrade returns an instant PSA-style condition estimate — an overall 1–10 grade plus centering, corners, edges, and surface subgrades — then helps you track, value, and sell your collection. It is a fast, low-cost pre-grading and collection-management tool, not a third-party certification service.

## What MasterGrade does

- **Instant AI grading**: Photograph a card (front and optionally back) and get an overall grade (1–10) with four subgrades — centering, corners, edges, surface — plus a plain-language condition label (e.g. "Near Mint", "Gem Mint"). Designed to predict how a professional grader (PSA/SGC/etc.) would likely assess the card before you pay for submission.
- **Multi-category**: Supports Pokémon (English and Japanese), sports cards (baseball, basketball, football, vintage), Yu-Gi-Oh!, Magic: The Gathering, Lorcana, One Piece, Dragon Ball, and other trading card games.
- **Collection & portfolio tracking**: Save graded cards, organize them into folders, and track estimated market value over time.
- **Marketplace**: List graded cards for sale with the AI grade attached, so buyers see condition up front.
- **Population & pricing data**: Cross-references PSA population reports and market prices to help estimate value.

## Who it's for

Collectors, flippers, and sellers who want to know a card's likely grade and value *before* paying for slow, expensive professional grading — and who want one place to catalog and price a whole collection.
