Usability test types: when to use each

A comparison of moderated, unmoderated, remote and in-person usability testing, with the situation each suits and what you give up. It is for product teams and UX researchers planning a usability study. Decide on moderation first, then on location, from your research questions, timeline and budget. Koji can run AI-moderated sessions remotely.
