The whole app, really
Snap one comic or a whole stack in a single frame.
A vision model reads the cover — title, issue #, publisher, year.
Skim the fields, fix anything, batch-accept. Fast by design.
Your collection, sorted by series, publisher, or value.
What you get
The camera plus a vision model collapses "type 40 fields per issue" into "take a photo." Grade, publisher, and estimated value come back filled in.
Comics have issue #, publisher, grade. Longbox already knows the right fields and snaps each capture onto the right collection — no near-duplicate lists.
See the holes in a run ("missing between #1 and #10"), build a wish list, and check live eBay listings from the cover.
Browse by value, see an estimated total for what you own, and mark issues to sell.
Your collection lives on your device. No accounts, no login, no cloud database of your stuff.
Export and back up your whole collection whenever you want. It's your catalog, not ours.
