About Arb Sentry

Your AI-powered watchdog for Pokemon card deals

Our Mission

Arb Sentry was built by Pokemon card collectors who were tired of manually scrolling through thousands of eBay listings looking for undervalued cards. We built the tool we wished existed: an AI-powered scanner that watches the market 24/7 and alerts you when it finds deals worth your attention.

How It Works

1. Continuous Scanning: Our system monitors eBay listings around the clock, scanning thousands of new Pokemon card listings 24/7 across multiple categories and search strategies.

2. AI Analysis: Each potential deal is analyzed by our AI system, which identifies the card, predicts its likely PSA grade based on visible condition, and calculates expected profit based on recent sold prices.

3. Deal Scoring: We combine profit potential, confidence level, seller reliability, and market liquidity into a simple 0-100 deal score that tells you at a glance whether a card is worth pursuing.

4. Instant Alerts: When we find a deal that matches your criteria, you get notified immediately via email so you can act before the competition.
