<span style="color: #0747a6">How long is the free trial?</span>

Our free trial lasts for 7 days. You will need to subscribe to our plan if you need to conduct further research. However, all your past test data will still be available in your account even if the trial has passed.


<span style="color: #0747a6">Is the test editable after it is launched?</span>

After launching the test, all your test setups will not be able to change or modify. However, you still can edit your task instructions, survey questions, and options.

This is to prevent any inconsistency in your result data and affect the system to generate a good analysis of a test. Therefore, we would suggest duplicating your test and having a dry run before sending it out to your participants.


<span style="color: #0747a6">How many participants can I have in a Test?</span>

There's no limitation on the number of participants in a Card Sort and Tree Test.


<span style="color: #0747a6">What’s the maximum size of a Tree in a test?</span>

Although our system accepts far more, in terms of research, we recommend not exceeding 20 sub-children in the same chain.


<span style="color: #0747a6">What's the maximum number of tasks I can create in a Tree Test?</span>

Our platform can support more in each test, but research-wise, we would recommend keeping the tasks within 30 tasks.


<span style="color: #0747a6">What's the maximum number of test responses that I can collect in a test?</span>

For each test, you can collect a maximum of 250 responses.
