Boost AI Search & Filter

This filter is exactly what I needed with its ingenious system of prefixes in tags, which allows to create a filter with different categories that are not in your products options/type/collection/etc. (For example if you sell tee-shirts, each in a unique color so the color is not in the variants, you can create a filter using tags like "color Red", "color Blue", and the filter will read "Red / Blue", and/or you can add a tag with prefix for the fitting or whatever you want, the possibilities are endless)
There are a lot of customization, including swatches for colors (you can use theirs or create your own), filter on the top or on the side of the page, text color, size... and many others.
The team is awesome, they helped me tirelessly and always kindly with the integration of the filter in my theme, some customization, and even going beyond their duty to help me with another app.

The best app I have in my store, I can have everything I want and it has helped increase my sales. Customer service is the best in response time and resolution.

Extraordinary app! Since I have more than 1000 items, I needed an app like this to easily filter products. I had a few issues, but customer support always solved everything quickly which helped me a lot!

Great app & excellent support. integrates with the theme layout very well. Highly recommended if your looking for an advance search & filter app.

The customer support is top notch! Really!

I installed the app which looked great out of the box, didn't have to change anything. However, I had some issue with my color variations and a few other minor issues. I contacted the support and in less than 12h, it was fixed!

Happy customer! Keep it up!

We have a lot of very different types of product, and the Boost Filter does a great job of sorting that all out for us and our customers. Additionally, some customization that was necessary went smoothly, and in particular their response time to messages has been excellent. Thank you !

Very flexible and intelligent app! And, I received excellent response from the folks in support. You get what you pay for and we feel this app is worth the subscription fee.

Great customer support. They were very proactive with my request and got exactly what I needed. Some changes were necessary during the process, but customer service always had a great attitude to fine-tune my request. Thanks a lot!!! I highly recommend this app.

Excellent support, fast responses to any queries, and quick fixes to any issues. Great customer service is what makes this app stand out.

I just want to commend Boost for their outstanding service. I had some problems when I first loaded the App and I was feeling frustrated. However their responsiveness to addressing every single fix was amazing. I have worked with many Shopify App developers however Boost are the best I have encountered. Plus the Filter and Search functions are now exactly what I want.
