A structured registry for serious collectors.
Record what you own. Prove what it is. Track its history.
Build a collection that stays understandable over time.
Designed for collectors who want structure, clarity and control over their collections.
No matter what you collect.
Collectaneum gives you the tools to document the items you own, their history, and what makes them unique.
Created by collectors who wanted more than a spreadsheet and less than a marketplace.
Most collections outgrow their tools.
Spreadsheets start simple, then become inconsistent. Photos live in folders. Receipts in emails. Notes scattered.
As collections deepen, details multiply — editions, printings, variants, condition, provenance, value.
Without structure, it becomes hard to trust your own records.
Designed as a registry, not a tracker.
Collectaneum models how collectibles actually exist — so your records stay consistent as your collection grows.
Structure
Franchise → Edition → Product → Variant → Owned Item
