SCORM is not a feature in Knowly. There's no SCORM player and no way to upload a SCORM package as an activity.
If you have SCORM content you want to use, host it yourself — on your own LMS, a web server, or anywhere it can be opened by URL — and link to it from a Knowly activity. Most activity types let you add a link: instructions, micro training slides, assignments. Participants open the link from inside the learning journey.
What you give up by linking out
Knowly only sees that the participant clicked the link. SCORM's built-in completion and score tracking does not carry over. If you need that tracking, build the content as a native Knowly activity — micro training, knowledge test, or assignment — instead.
