About us. In 2004, two usability consultants set out to create a quick and easy way of running a remote card sort. This led to an innovative online card sorting tool called OptimalSort, where they discovered the benefits of remote user testing, setting them on a path to develop an entire suite of powerful UX tools.. In 2007 Optimal Workshop was born.
An Optimal Workshop account on the free plan lets you explore all 5 Optimal Workshop tools: Treejack, Chalkmark, Reframer, Questions and OptimalSort.
