How do the Katalog.world algorithms works if the official brand data has not been distributed to Katalog.world?

NB: Katalog.world does not sell data, it is a tool for collecting, researching, compiling and formatting data to meet a need expressed by the user (professional or not).

It is the first product data crowdsourcing tool.

In the event of a request by a retailer on an unknown GTIN (the brand does not yet collaborate with Katalog.world), the algorithms will try to collect data to respond to the request.

Katalog.world then scours the web to find the data and aggregate different sources to meet its mission.
=> Generate a product sheet.

It is therefore possible that the algorithms collect incomplete or unreliable informations.
The user is made aware of the relative reliability of the data thanks to a score assigned for each data by Katalog.world.
But in any case, the user will be the only decision maker whether or not to use the data for his catalog.
