The problem that affects majority of $4b online education market is - no one watches educational videos to the end.
Only 10% of students get to the end.
In 8 years of experience in online education we learned by heart, that the major reason is lack of interactivity.
You can't see the structure of the videolecture, can't navigate to the subjects you need, you get bored, you drop off.
Now in United Lectures (Ulect) we build the table of contents of the video allowing quick navigation, we synchronize the with slides and publish this interactive lecture with tests, comments, Q&As and mobile access.
We also use AI and symantic analysis to automatically extract the keywords discussed in the video and build a tag list with links to the those moments.
It's a publishing service for authors of the content - we publish the interactive videos on our "skillshare"-type portal, or embed at customer websites/intranets/mobile apps.
