Creating a conlang is usually only half (or less than half!) of the necessary effort: someone has to be able to learn it, unless you want to keep it as your own private secret code.
I use Duolingo to learn various languages, and it does of course have an Esperanto course on it, as well as Klingon and High Valyrian. However, it is unlikely that it will feature many more Conlangs, especially not one that you will develop yourself.
Now, it is of course not feasible to re-implement all of Duolingo's features, but I was just wondering if there are any apps/websites that you can use to develop an on-line course for your own conlang (it has to be fully automated, with no human teaching involved).
Is there something along the lines of Duolingo available where you can create your own courses?
