I run Primerlabs(https://primerlabs.io https://primerlabs.io) and it addresses some problems that learner face while completing the course. For a long course on, say OCW or eDX, if you stop midway, and try to resume after a couple of months (for whatever reason), you will find that your memory about the topics covered is less. And videos or books aren't really good platform to review what you have learned. ( I wish there was an "Recap" button just like in Netflix series). On Primer, learners have to respond forcefully which later on helps them review the courses easily. You can do some topics, quit for a while and retrace/recover using what you learned using flashcards and your own responses. It introduces "resumability" which other learning platforms lack. I wrote a blog post on why Primer's conversational system is better, if you are interested to know more. https://primerlabs.io/comics/memory-breadcrumbs-comics/ https://primerlabs.io/comics/memory-breadcrumbs-comics/
