Hello Hacker News!<p>I'm looking for feedback for my side project, Sagefy. I've been working on Sagefy for a little over 3 years and finally have something to show! I describe Sagefy as an open-content adaptive learning system. You can think of Sagefy like a synthesis of "anyone can edit" from Wikipedia and adaptive learning systems like Aleks or Knewton.<p>Here's a short 3-minute explainer video: <a href="https://www.youtube.com/watch?v=HVwfwTOdnOE" rel="nofollow">https://www.youtube.com/watch?v=HVwfwTOdnOE</a><p>All of the basic things are built, but Sagefy is still a little rough around the edges. You can try out a little course I've built in it, "Introduction to Electronic Music -- Foundation", at: <a href="https://sagefy.org/" rel="nofollow">https://sagefy.org/</a><p>Sagefy is completely free and open source <a href="https://github.com/heiskr/sagefy" rel="nofollow">https://github.com/heiskr/sagefy</a> . I have no interest it turning this into any sort of commercial endeavour. If you're interested in getting more background, check out the Wiki at <a href="https://github.com/heiskr/sagefy/wiki" rel="nofollow">https://github.com/heiskr/sagefy/wiki</a> . Or just ask :)<p>Let me know what you think! And thank you!
