Boost AI Search & Filter

This app is really incredible. I installed it on two different Shopify stores and both times the install took some time. If you have modified your theme at all, you are likely to run into some issues if you try to run the automatic install. However, Boost Commerce has excellent support and was very helpful in getting the filter set up properly. They charged a fee of $ 150 for one of my installs, which I found perfectly reasonable, considering the work involved in setting it up with my custom theme. Highly recommended!
