Edpuzzle is aimed at teachers. Via Edpuzzle you can add interactions and voice-over to existing YouTube videos or you can upload your own video. The interaction list is minimal. Only two types of questions and notes are on the list of interactions you can add. In the notes, there is the possibility to add a hyperlink.
The interactions are added to the timeline and will show up in a sidebar when the video arrives at that particular timestamp. The teacher can send the finalized video to their students and view the results. You can, however, upload a video or use a video from another teacher.
Edpuzzles interactivity is minimal yet effective. If you, however, need more interactivity in your video then hihaho might be the better option for you.
