How It Works

AI that thinks like a collector, moves like a bot

🔍

Cross-Marketplace Scanning

eBay, Mercari, Facebook Marketplace, convention vendors, retailer drops. One AI watching them all simultaneously.

Instant Deal Alerts

The second a grail appears underpriced, you know. Not tomorrow. Not in a digest. Right now.

📈

Price Intelligence

Historical pricing, rarity scores, and trend analysis so you know if a deal is actually a deal.

🎪

Convention Mode

Gen Con, SDCC, NYCC season? GrailRadar tracks exclusive drops, vendor deals, and limited releases in real time.

The Problem

Every collector has the same 2am story

You set eBay alerts. You check Mercari before bed. You join Facebook groups with notifications on. And somehow, you still miss the one listing that mattered.

That's because humans can't monitor five marketplaces simultaneously. But AI can. GrailRadar doesn't sleep, doesn't forget, and doesn't get distracted by doom-scrolling.
