7 Best card sorting tools for UX research

It’s easier than ever to conduct a remote card sorting study, with endless digital tools to choose from. To help make this decision, this final chapter will reveal our top picks for digital card sorting tools to make your UX research easier and more impactful.

What tools do UX researchers use?

It’s crucial to select the right tool for your UX card sort, but it’s a daunting decision to make. You need a tool which is easy to set up, intuitive for participants to use, and offers robust data capture and analytics.

Within user research, card sorting is an effective way to uncover how people organize information, test assumptions, evaluate existing mental models and come up with new ones. It can uncover how your target audience relates and categorizes concepts and how their domain knowledge is structured.

Guillermo Gineste, Senior Product Designer at Maze

Today, most UX researchers opt for a remote card sort over in-person options. Not only are digital card sorts easier to set up, but they allow access to a wider research participant pool, and dramatically reduce the administrative burden of manually sorting and analyzing results data.

To get some insight into what real designers and researchers are looking for in a card sorting tool, we spoke to some of our product team.

Guillermo Gineste, Senior Product Designer, says the emphasis of any online tool you’re considering should be on usability, just as it is when designing a product. “Card sorting can be very daunting; it can be difficult to run and analyze, so anything that simplifies this process and makes it accessible is really attractive.”

It’s also critical to think about how testers will see the tool. If users are having trouble understanding how to use the card sorting tool, it can impact your end results.

When it comes to data, Netali Jakubovitz, Group Product Manager at Maze, notes that while more powerful analysis is important, it’s also crucial to think about how usable that analysis is outside the tool.

“It sounds obvious, but too many times a card sorting tool has great usability, until you reach the results. Often, it’s really just a lot of numbers and tables thrown at you. Finding a tool that offers an easy-to-understand overview of the results, with the option to further expand the results and dig deeper, is so valuable.”

UserZoom offers both open and closed card sorting through a digital platform and streamlined user process. As with most other tools on this list, the tool offers analytics which include participant completion time and a similarity matrix.

The downside of UserZoom is its missed opportunity to offer reporting features, as other tools do. Nonetheless, there is a useful feature which allows researchers to copy data from results in a format that can be pasted directly into Excel.

Type of card sort: Open, closed
Works on: Browsers
Pricing: UserZoom does not offer card sorting on its free plan. Paid plans start at $250 per month.

3. Miro

Miro is a tool that we all know and love—the ‘online whiteboard’ built for collaboration is a platform with endless uses, including card sorting.

The beauty of Miro is that it’s a simple concept with the capabilities of a complex, digital tool. This is what makes it so great for card sorting. A whiteboard is often a UX researcher’s starting point for an in-person card sorting session, and Miro simply takes this online.

Beginning with a blank page, Miro is the ideal starting point for any UX researcher. The in-depth design and organization capabilities in turn allow for creation of thoughtful, detailed card sorting studies, completely customized to your own goals and product.

The big downside to Miro as a card sorting system is that it doesn’t offer any post-study analytics, so it’s on you to get analyzing. That being said, if you’re looking for as close to an in-person card sort as possible, Miro’s the tool for you.

Type of card sort: Open, closed, hybrid
Works on: Browsers, Mac, Windows, Android, iOS
Pricing: Miro is free for up to three boards, with paid plans starting at $10 per user/month

4. OptimalSort

Quick to set up and easy for users to work with, the tool functions as you’d expect, with simple drag-and-drop interactivity. After the sort, data analytics allows the researcher to easily identify common groups and clear similarities, with some solid data visualizations and a downloadable report card.

Similar to UserZoom and Maze, Optimal Workshop offers in-platform recruitment, so researchers working with OptimalSort can directly reach out to potential participants.

While there aren’t any outstanding analytics available, kardSort allows results to be exported to various analysis tools and spreadsheets for later manual analysis. An additional feature which proves useful is the option to add an information icon and pop-up to cards or categories as you see fit, which may be particularly useful for certain topics or specific terminology.

How do you sort cards in UX design?

Card sorting is a UX research method used throughout the UX design process, as a way to discover how people understand and categorize information.

In UX design, participants in a card sorting study would be asked to move different cards into categories—either pre-created or created by the participant—as it feels natural to them. This can be done in person with paper cards or remotely, using a digital card sorting tool.
