Every topic, subtopic, and lesson is free to browse — no account needed. Flashcards, quizzes, visuals, and narrated audio overviews are all available today.
Accounts are on the way, bringing playlists, watchlists, favourites, and video. Two new tools are planned too: Test Maker (custom tests & interview prep) and Release Radar (what’s new and next per topic).
Topics are now grouped into categories — Frontend & Web, Languages, Backend, Cloud & DevOps, AI, Security, and more — with new tracks and lessons shipping continuously.
