01
Capture the object
Photograph an item, import an existing inventory, or rapidly queue records while working in the field.
Your collection, understood
Know what you own. Track what it becomes.
Catalog physical collectibles, understand their estimated value, and follow the full arc of your collection—from first photograph to portfolio performance and ownership continuity.
Begin free. Market-research estimates are not certified appraisals.
The founder promise
Built for the record, not the reveal.
01
Evidence over certainty
Estimates include context and confidence. When better evidence could matter, CollectionArc tells you exactly what to add.
02
Privacy by default
Sharing uses deliberate projections—not your private holding, storage details, serial numbers, costs, or values unless you choose otherwise.
03
History stays traceable
Value, classification, location, and ownership changes are preserved so today’s portfolio never erases yesterday’s record.
From object to intelligence
Identification starts the record. Structure makes it valuable.
CollectionArc turns scattered photos, spreadsheets, and marketplace searches into a living portfolio you can query, improve, protect, and carry forward.
The durable portfolio
See concentration, value, custody, and performance in one coherent view.
Estimated value
Current research-backed value by item and collection
Category allocation
What you own and where collection value is concentrated
Custody & location
Box, shelf, cabinet, binder, loan, repair, or consignment
Ownership performance
Costs, dispositions, gains, losses, and full holding history
02
Confirm the evidence
AI-assisted identification asks for the smallest useful detail—such as a maker’s mark, mint mark, model plate, or grading label.
03
Build the portfolio
Organize holdings with CollectionArc’s definitive taxonomy, storage hierarchy, tags, assemblies, and virtual collections.
04
Track what changes
Follow estimated resale value, category allocation, market interest, costs, gains, losses, and ownership history over time.
One record
Preserve evidence as identification improves
Many views
Use tags and virtual collections without double-counting value
Full continuity
Carry the object’s digital identity across ownership periods
