In the complex ecosystem of Retail Media, strategic differentiation is your greatest asset. Until today, artificial intelligence in catalog optimization followed rigid patterns, often resulting in cloned listings that failed to capture the essence of your brand or the specificities of strategic channels like Amazon, Shopify, or eBay. You don’t need a tool that simply “writes”; you need an infrastructure that allows you to inject your own sales expertise into every word. At Epinium, we have evolved to ensure your AI agents act with the precision and tone of voice that your global strategy requires, always guaranteeing your brand’s sovereignty.
The New Personalized Prompt Library
Personalization at scale is now a reality. With the new Prompt Library, you can design, store, and reuse specific instructions for each market, language, or product type. This ensures your brand’s narrative remains consistent across all your channels, whether you’re optimizing 10 or 10,000 references. 
Advanced Multi-channel Segmentation: Clusters and Filters
Operational efficiency in Retail Media relies on finding what matters, fast. We have enhanced the catalog table with next-generation filtering and organization capabilities:
1. Strategic Linking with Clusters
You can now link specific prompts to your Product Clusters. This allows the AI to automatically understand the context of each group: apply an “Aspirational” tone to your fashion collections on Shopify and a “Technical” tone to your industrial accessories on Amazon, without repetitive manual interventions. 
2. “Cluster” and “List” Filters for Massive Catalogs
Navigating thousands of products is now instantaneous. The new Cluster filter allows you to manage logical groups in seconds, enabling you to isolate exactly the part of the inventory you want to work on. 
On the other hand, the List filter is the perfect ally for agencies: it allows you to paste multiple values (SKUs, EANs, ASINs) directly from an Excel sheet to filter the entire table with a single click, eliminating manual individual search work. 
Mass Optimization with Strategic Intelligence
The true power of this feature lies in the Bulk Optimizer. You are no longer limited to predefined settings; you can select your own personalized prompt from the library and apply it to thousands of products simultaneously on Amazon, eBay, or Shopify, maintaining artisanal quality at an industrial scale.
Intelligent Hierarchy: The Control is Yours
To ensure predictable results in multi-channel environments, we have designed a hierarchical resolution logic that avoids any data conflicts:
-
Priority 1 (Bulk): Your manual actions in bulk edits have maximum authority over the catalog.
-
Priority 2 (Cluster): If there is no manual action, the prompt linked to the cluster is applied (prioritizing the most recently updated one).
-
Fallback (Standard): If there is no active personalization, our expert agents intervene with the default optimized prompt.
Strategic Vision: The Path to Agentic Commerce
This update is a fundamental pillar of Agentic Commerce. We are transforming catalog management into a network of empowered AI Agents that understand your business vision. By personalizing your prompts, you are training your digital sales force to execute your strategy with maximum retail excellence. The result is total Brand Sovereignty and unprecedented multi-channel scalability. You lead the strategy; your agents execute success.
FAQ: Personalized Prompts in Epinium
What does the new Prompt Library actually let me do?
Design, store, and reuse specific AI instructions for each market, language, or product type, so your brand’s narrative stays consistent whether you’re optimizing 10 listings or 10,000.
How does linking prompts to Product Clusters work in practice?
You link a specific prompt to a Product Cluster so the AI automatically applies the right context — for example, an “Aspirational” tone for fashion collections on Shopify and a “Technical” tone for industrial accessories on Amazon — without manual intervention on each product.
What is the “List” filter useful for, specifically for agencies?
It lets you paste multiple values — SKUs, EANs, or ASINs — directly from an Excel sheet to instantly filter the entire catalog table down to exactly the products you want to work on, skipping manual individual searches.
If I set both a manual bulk edit and a cluster-linked prompt, which one wins?
Manual bulk actions always have top priority. If there’s no manual override, the cluster-linked prompt applies, using the most recently updated one; if neither exists, the default optimized prompt from Epinium’s expert agents is used as the fallback.
Can I apply a personalized prompt to thousands of products at once?
Yes — the Bulk Optimizer lets you select a personalized prompt from your library and apply it across thousands of products simultaneously on Amazon, eBay, or Shopify, keeping quality consistent at scale.
