About mustard : Instant Smart Search

Deliver better search results and see your revenue grow!


Even when conventional search delivers results, they are a poor reflection of the amazing products on your store. Your shoppers might be looking for inspiration (for an interview, a date, a party), they might be looking for similar brands, they might be looking for an idea in their head (red and blue polka dotted dress). mustard can answer all these and more, because it looks at your store product images and understands them like a you and I would!

mustard uses the leading AI image models to match search queries to product images and more.

Think about the time when you head over to Google and don't have to think about typing the exact phrase in the search box. mustard puts that level of intelligent search on your store, making it super easy for Shoppers to find what they are looking for.

So shoppers are much more likely to click and purchase the products that they find. Get mustard today and helps your shoppers discover the products they love!


Here are some top advantages to moving to the power of mustard search:

  1. Cover 2x searches over conventional search
  2. Match the meaning of search terms rather than just the words!
  3. Monitor keywords, searches, revenue and orders from search
  4. Discover opportunities to grow!


We'll help you understand search performance on your store. Even if you don't use mustard for your store, we'll make sure you understand the power of search for your store!


Here are some more amazing things we are building with mustard:

  • Promoting products within search results
  • Suggesting searches to inspire discovery
  • Recommending products like a friend
  • Filtering products on the basis of ideas

But we'd love to hear what you would like us to build.

Mustard is a great spice for your website which is using the Shopify standard search. This app brings relevant search results even on typos. Furthermore it has a very simplistic interface without funky bells and whistles, blends well with the theme. There is a great technical support as well.

Thanks Erce! We think of it more as "human support". Really excited about search on your store.


Awesome app that is using some next-level technology. Especially helpful for stores with a high volume of SKU(s)! Installing it is a no brainer. Thanks for the great support as well!

Mustard has enhanced the search results on our website. For so many search terms, the default Shopify search was not showing any results, but mustard has solved that. Customers are actually able to see more refined search results, which is helping in their purchase decision. Their analysis is very insightful. I can see search terms that are resulting in sales. Mustard's team is very very experienced and available 24x7. They responded to my queries in real-time. A must-have app for all eCommerce stores.
