Never miss another grail. GrailBot scans eBay on autopilot, scores every listing by rarity and grade, and adds winners to your watchlist while you sleep, even when sellers misspell the card name. And it learns what you collect.







GrailBot runs this loop around the clock, learns what you're looking for, and improves every week.
Every listing is rated 0–100 based on set tier (Prizm, National Treasures, Base Set…), parallel rarity (Superfractor, Gold, Alt Art…), grading company and grade, autographs, patches, and print runs. Set a threshold once, and GrailBot handles the rest.

Same player. Same set. Very different cards.
GrailScore scores the details a quick scroll misses, so only the best ones reach your watchlist.


Search, complete, and spot deals across sports & TCG — GrailSense learns your taste and tunes all of it.

GrailScore is a weighted 0–100 number derived from set tier, parallel rarity, grading company and grade, features (autos, patches, print runs), and recent sales velocity. The weights are tuned for collectible market dynamics. Pro users can set a minimum score threshold to auto-filter listings, and Pro-tier GrailSense personalizes the score for what you collect over time.
