Hello!
I am a member of the Polish Diaspora in the Kuban and my colleague and I have created such a program for the telegram messenger which teaches the Polish language.
The system is such that on the day 5 messages are sent, they look like this:
Polish: uczeń
Translation: schoolboy
Transliteration: эньэньэньэнь
The very purpose of this bot is to replenish the vocabulary.
We are waiting for you on our channel and success in learning the language!
