Sorry, this is a commercial project, not open source. In fact, if this fails, we will starve.
Anyway, it is the core of this app that automatically connects the naturally written note-taking into a form that can use Spaced Repetition. It's hard to explain in more detail, but I hope you enjoy the experience of being able to use Spaced Repetition for the content by simply taking notes in outliner form. Anyway, thanks for the compliment.
“Commercial” is not incompatible with “open source”. If you have a policy of “release last year's version under AGPLv3” (and then buy indefinite proprietary licenses for the best community patches off their authors), we'll all benefit from open source without you having competitors leeching off your work.
In fact, some companies can do it with no time delay, like https://plausible.io – but, of course, it depends on your business model and your field.
