AI Sourcing

From gut feel to grounded sourcing.

Still writing titles and descriptions one by one?

Auto-generates titles, descriptions and selling points with multilingual support — extensible to bulk listing, inventory, pricing and status management.

Less repetitive work, faster listings.

AI Support / RAG

AI Support / RAG

Leaving that midnight English inquiry until tomorrow?

Builds a knowledge base from product data, logistics rules and after-sales policy to answer common questions automatically, in multiple languages — complex cases hand over to a human with full context.

Answers that are faster, more consistent, better grounded.
