There aren’t that many good card sorting tools out there on the market. However, it can still seem hard to choose the one. It’s necessary to be aware of all of the options as in some cases, their features vary quite significantly. 

In this guide, we compare some of the most popular options, their features and pricing as well as list all the benefits. But first, let’s see why online card sorting tools (and their good selection) matter. If you need a refresher on what card sorting is and how it works, read more of our guide.

Why do you need an online card sorting tool?

A good card sorting tool helps you streamline the card sorting activity and process all collected data for easier analysis. Offline card sorting without using a tool is a rather long complicated process where any complex analysis requires you to be a spreadsheet wizard and is prone to human errors. Working with a specialized tool saves you time and money.

Conducting your study online without moderation also allows you to test an unlimited number of respondents, leading to results where you can be sure about their statistical reliability. A good card sorting tool gathers all the user insights and transforms them into actionable data (such as shareable reports, graphs and tables that are easy to analyze). It basically  takes care of all the dirty work, allowing you to focus on understanding your users.
