Mintachu – AI-assisted Pokémon TCG grading and market analysis

Summary: Mintachu is an AI-powered research assistant that searches eBay listings, analyzes card photos, predicts PSA grades, and provides real-time market pricing to help identify undervalued Pokémon cards. It uses multiple specialized AI agents to evaluate card condition and grade predictions, streamlining the manual research process for collectors.

What it does

Mintachu searches eBay for Pokémon card listings, analyzes front and back photos using AI agents, predicts PSA grades, and displays market values to assess deal quality. The system coordinates four AI agents—front analyzer, back analyzer, grader, and auditor—that sequentially evaluate and refine the card’s condition and grade.

Who it's for

It is designed for Pokémon card collectors and hobbyists who want to automate and improve the accuracy of card condition research and investment analysis on eBay.

Why it matters

Mintachu reduces the time-consuming manual process of inspecting listings and comparing prices by providing AI-driven condition assessments and market insights as a first-pass filter before detailed human inspection.
