Watch in English. Study in Spanish.
Generate your study materials in a different language than the source. Great for language learners — and for studying in the language your exam actually uses.
Afterwards
Nothing here is a dead end.
Every artifact can graduate into a note.
Save any output straight to your Notes as clean markdown — then wiki-link it into the rest of what you know. Today’s lecture becomes part of the bigger map.
Explore Notes →Everything you’ve made, one search away.
Every artifact lands in your Workstation history — search by title, filter by source type, and reopen last month’s study kit the night before the exam.
