Documented

A source is recorded. This alone does not establish authenticity.

Claimed

Stated in a catalogue or by a seller, not yet supported.

Open

Missing, with the next step to resolve it.

Why Ploroq

The art market runs on claims. Ploroq keeps them apart from evidence, so you can see where an account comes from.

One record per work

Photographs, scans, correspondence and catalogue pages stay attached to the object they describe, not scattered across inboxes and folders.

A source behind every line

Record the source and review status of important details. We confirm the processing scope for your pilot.

Gaps become tasks

What is missing is listed, with the next step: photograph the reverse, request the invoice, check the exhibition list.

The record

The same work. Read two ways.

A catalogue entry can mix evidence, claims and hypotheses. This example shows how a record can separate them.

Illustrative record with fictional data. Not an authentication or valuation.

How it works

Start with a single work.

No migration project and no new filing system to learn. The pilot begins with one artwork you are working on now.

I.
Bring what you have
Photographs, scans, invoices, letters, catalogue pages. Incomplete is fine; that is the point.
II.
Every detail meets its source
Facts are written once and tied to the page, image or document that supports them.
III.
Know where you stand
Documented, claimed and open, side by side, with agreed next steps.

Who it's for

For those who have to answer for a work.

Prepare the evidence for questions from a buyer, an insurer, a museum or an expert.

Galleries & dealers
Prepare documentation for a sale or loan. Distinguish supported information from open questions.
Private pilot
Collectors & advisors
Keep a collection's history, invoices and images together, ready for insurance, sale or inheritance.
On request
Experts & researchers
Separate supported information from hypothesis before an opinion is written.
On request

Photographic, heritage and other professional archives are assessed case by case.

Principles

Rigorous about evidence. Honest about its limits.

No verdicts

Ploroq shows what is documented. Authentication remains the work of experts.

No automatic valuations

A price recorded in a source is not a current valuation. Expert valuation is a separate service.

Private by default

Records belong to your workspace. Access is by invitation and permission.

People decide

An AI suggestion is not an approved conclusion. We agree on AI use and human review for your pilot.

Bring one work.

Tell us about an artwork you are researching or preparing for sale. We will show you what its Ploroq record would look like, and how the private pilot works.
