Not exactly the thread topic, but found something useful
 
Just while searching for educational platforms I found a site https://tools.veryuseful.website/
 
They’ve collected:
- online libraries (like "Українська Література"),
- free courses via Prometheus,
- Duolingo for learning Ukrainian,
- information about schools and universities.
 
Really great collection.
 
Also found <a href=https://tools.veryuseful.website/> an awesome Ukrainian learning platform</a> — maybe worth checking!
 
Any other cool learning sites to recommend?
