How it sells itself

FathomRetail is an AI-powered search solution that understands your customers’ natural language queries and delivers highly relevant results. It can be easily configured to provide a delightful customer experience attuned to your domain. The smart search bar understands natural language and works seamlessly with the filters to deliver relevant results. Easily integrates with your theme and runs out of the box!!

Shopify's default search only finds products when customers type exact keywords. When shoppers search naturally, like "something for dry patches on my face" or "gift for someone who loves cooking," they get no results and leave. Understnd replaces keyword matching with AI that reads customer intent. It matches searches to relevant products based on meaning, not just words. Setup takes minutes.

Key points
  • Grasps customer's intent and returns relevant results
  • Filtering through smart search bar e.g. "blue, slim fit formal shirts under 800"
  • Multilevel filters work seamlessly in combination with the customer search query
  • Easily integrates with your theme
  • AI search that understands natural language
  • See what customers search for with real-time search analytics
