HobbyMonitor

HobbyMonitor connects your HobbyMonitor account to Claude so you can work with your real card collection and prospect data in plain language.

Your collection

List your collections and search your cards by player, set, year, parallel or card number, with filters for graded and sold cards. Open any card's full record: grading, serial number, value, price history, purchase details, notes and storage location. See front and back card images, and have Claude review them for a listing, a social post or a condition check. Add cards by hand or import a graded card from its cert number, update any field, and remove cards (Claude previews a removal before it happens).

Prospect research

Search and rank baseball prospects by price, position, level, team and season stats such as home runs, OPS, ERA or strikeouts. Get a full prospect profile: scouting grades, recent news, injury status, HobbyMonitor ratings, current 1st Bowman autograph values and stats broken out by season and level.

Plans and access Reading your collection works on every plan. Prospect research, card images and collection edits need a HobbyMonitor Premium or Pro plan. You sign in with your existing HobbyMonitor login. Head to the website or download the mobile to sign-up if you need an account.
