Deklarium

Which of your product
images came out of
a generator?

Deklarium reads every image in your Shopify catalogue, finds the AI generated ones, proves it, and puts the notice in your storefront with one switch. Thousands of images, one afternoon, no spreadsheet.

The difference

Finds signatures other tools never see

Generators write a signed C2PA record into the file. Shopify's CDN deletes it when it converts the image for your storefront. Every tool that reads the delivered image comes back empty.

Deklarium asks Shopify for the file you originally uploaded. The signature is still in there. That is why it comes back with a name, a timestamp and a valid signature where others report nothing.

Evidence

Every finding comes with its reason

No bare verdict you have to trust. Deklarium says which signature it found, which field it came from, or why the image analysis reached its conclusion. You can read it, check it, and defend it later.

And you always have the last word. Overrule any finding with one click, and take that decision back just as easily.

In your storefront

One switch, and the notice is live

Turn on the theme extension and the notice appears on the product pages of the images you marked. No theme code, no developer, no copy and paste into a thousand descriptions.

Wording, tooltip and position are yours, in German and in English. Switch it off again and it is gone from the storefront.

Records

The whole catalogue as one document

Export the state of every image: which product, which finding, on what basis, at what time, and whether the app or you decided. As a spreadsheet for your files, or as a printable document to hand over.

Scans run in the background. Close the tab, come back tomorrow, the run is where you left it.

How it works

Installed, scanned, labelled

1

Install and start

Install from the App Store, press start. Deklarium works through the catalogue on its own.

2

Go through the findings

Sort by finding, read the reasons, correct what you see differently. Bulk decisions for whole batches.

3

Switch the notice on

One switch in the theme editor. From then on new images are checked automatically as they arrive.

Everything else

What is in the app today

C2PA and JUMBF

Reads signed provenance records and reports generator, time and whether the signature validates.

IPTC DigitalSourceType

Reads the IPTC source field that many tools set even without a signature.

Image analysis

Where a file carries no trace at all, the picture itself gets assessed, with the reasoning in writing.

Duplicate detection

Identical files are matched by content fingerprint. The same image classified two ways gets flagged before you save.

Bulk decisions

Select many images in one dialogue, see each of them, decide for all at once.

Automatic for new images

When a product changes, its new images get checked without you starting anything.

Resumable runs

Stop a scan, restart it later, it picks up where it stopped rather than starting over.

German and English

Interface, findings, report and storefront notice all exist in both languages.

No customer data

The app reads product images and titles. It has no access to orders, customers or payments.

An image counts once a month no matter how often it is checked. An image analysis is only spent when a file carries neither a signature nor an IPTC field, so most stores stay well below the limit. Billed through Shopify, ends when you uninstall. Prices net.

FAQ

Questions we actually get

Does the app change my storefront on its own?

No. The notice appears only after you switch on the theme extension, and you set the wording. Until then Deklarium only reads and records.

Why does another tool find nothing where Deklarium finds a signature?

Because most tools read the image as your storefront delivers it, and Shopify's CDN drops the signature during conversion. Deklarium requests the originally uploaded file, where it is still intact.

Do my images leave the store?

Only when a file carries no metadata of its own and the picture itself has to be assessed. Images with a signature or an IPTC field are decided without being sent anywhere.

How long does a full catalogue take?

Images with metadata are decided in a fraction of a second. Only images without any trace go to analysis and take longer. A few thousand images typically finish while you do something else, and the run keeps going with the tab closed.

What happens when I uninstall?

The subscription ends, the storefront notice disappears, and Shopify removes the findings stored on your products. Export the report first if you want to keep it.
