Open-source tool for Duolingo-like courses

I'm launching UneeBee, an open-source tool for creating interactive courses like Duolingo:

GitHub repo: https://github.com/zoonk/uneebee
Demo: https://app.uneebee.com/

It's pretty early-stage, so there's a lot of things to improve. Everything on this project is going to be public, so you can check the roadmap on GitHub too: https://github.com/orgs/zoonk/projects/11

I'm creating this project because I love Duolingo and I wanted the same kind of experience to learn other things as well.

But I think this could be useful to other people too. I'll soon launch three products using UneeBee:

• Wikaro: Focused on enterprise. It allow companies to have their own white-label Duolingo. I think this is going to be great for onboarding and internal training.

• Educasso: Focused on schools. It will allow teachers to easily create interactive lessons, compliant to local school curriculum. I want to make it in a way that saves teacher's time, so they focus more on their students rather than lesson planning.

• Wisek: Marketplace for interactive courses where creators will be able to earn money creating those courses.

I'm not sure this is going to work out but, worst case scenario, I'll have products that I can use myself because I'm a terrible learner using traditional ways. Interactive learning is super useful to me, so I hope it will be to other people too.

If you have some spare time, please give me your brutal feedback. I really want to improve this product, so no need to be nice - just let me know your thoughts. :)

PS. I'm also launching it on Product Hunt: https://www.producthunt.com/posts/uneebee
