Sort yourself out with this comprehensive list of card sorting tools, from free online apps to robust user research platforms.
Since 1996, Nielsen Norman Group has been conducting large-scale usability studies to pinpoint the most common and enduring web-design mistakes. Number one on their list of enduring offenses: unexpected locations for content.
This is, of course, a problem. After all, “people can’t use information they can’t find.”
Sometimes, the problem is a result of confusing or misleading category names that don’t accurately describe what’s behind each “door.” Sometimes, a company has organized content based on their own internal biases, which don’t align with the visitor’s mental models of how information should be structured. Either way, poorly thought out content categorization creates unnecessary hurdles for users.
Luckily, a little usability research can go a long way toward improving your information architecture.
🎙 Listen: What Is Information Architecture, Anyway? with Page Laubheimer of NN/g
Card sorting is a research method used by UX and user researchers to uncover users’ mental models and better understand how people naturally categorize information. It involves having study participants group information by sorting cards into categories.
Open card sorts are the most common and are especially helpful at the beginning of a project when you’re trying to get initial insight into how people categorize and label information.
Closed card sorts are typically used later in a project as a way of validating whether category labels are clear and make sense to users.
Hybrid card sorts are often used on redesign projects. This approach allows the researcher to see how participants engage with existing information architecture while leaving space to explore additional categories that might make sense as part of an update.
In addition to card sort type, there are a couple other variables to consider. Namely, will your research be moderated or unmoderated, analog or digital?
To moderate or not to moderate, that is the question.
Pick your poison: old-school paper or new-fangled technology.
Whether you go remote or in-person, moderated or unmoderated, paper or digital, there are some considerations that remain consistent:
Digital card sorting is a fast and easy option. And in 2021, it’s also more the practical one, all things considered. Whether you routinely conduct card sorting as part of your UX research and are looking for an alternative to your current solution, or are an occasional researcher in the market for a straightforward tool, this list of 15 card sorting tools has you covered.
Some of the tools are available as features within broad UXR platforms, others are flexible tools that you may already be using and which you can adapt for card sorting use, and then there are some standalone options that are designed specifically for the task at hand.
💍 Can one tool rule them all? Explore the differences between all-in-one UX research tools and integrated, best-in-class tech stacks.

This free card sorting application is designed for UX professionals and social scientists. The product offers a visual environment that supports open, closed, and hybrid sort types, as well as the ability to create subgroups of participants. It provides statistical results (cluster tree, distance table, etc.), which are updated in real time. It has basic reporting functionality with export options, and researchers can lock the document so that each participant may only do one session. Note: xSort is only available on Mac
This simple and free online card sorting tool offers a straightforward drag-and drop format that makes it easy for participants to jump right into open, closed, or hybrid sorts. The application also has the ability to include pre- and post-study survey questionnaires; export results to .csv, SynCaps V3, and Casolysis; establish secure access via a password; as well as append cards and categories with additional detail under an information icon.
As will all user research methods, there is an art and a science to planning and analyzing card sorts. But the exercise itself is fairly straightforward, and all of the tools on this list will enable you to conduct effective remote card sorts. The devil is really in details—do you need a tool that offers analytics or will you import your data into another tool? Are you looking for a card sorting feature as part of a broader (and pricier) suite of tools, or are you mainly in the market for a quick and easy (and cheap solution)? Only you know the answers to those questions.
But one thing is certain: No matter which card sorting tool you choose, you can’t run a card sorting study without participants.
User Interviews offers a panel of over 500,000 vetted participants—recruit for research on any platform, or manage a research panel of your own in Research Hub. User Interviews’ Zoom integration allows you to schedule sessions, manage participant communication, and automate the creation of Zoom links—which means you can focus on actually researching, instead of getting mired in research ops.
