Stepik courses

Stepik hosts thousands of courses, and the hard part is not finding a course but finding the one that matches what you actually want to learn. The bot narrows that down inside the chat: you say what you are after and it returns a course from the platform.

For someone starting with programming in Russian, the platform behind it is the point — a large share of the free introductory courses in the language sit there, including university-made ones. The bot is a shortcut into that catalogue rather than a learning tool of its own.
