The science is settled and the behavior hasn't budged: spaced repetition with active recall beats re-watching lectures by a distance, and almost nobody does it — because making the cards is the tax. A forty-lecture series means forty card-making sessions, each requiring you to re-process the lecture you just sat through. Students who swear by flashcards mostly swear by them for one exam, once.

The cards were always derivable from the lectures themselves — every definition, distinction and worked example a card waiting to be cut. What was missing is the labor. Remove it, and the best-evidenced study method stops being aspirational.

library_import_youtube_channel ingests the course in one command — point it at the lecture playlist and every session lands in your veridive library, transcripts included. run_youtube_tool's flashcards then cuts the deck per lecture, from what the lecturer actually said: definitions, contrasts, the examples they emphasized.

Batch it across the series and the semester's review infrastructure exists by dinner: a deck per lecture, importable into your spaced-repetition app of choice. The afternoon you spend is on the reviewing — pruning cards you already know, sharpening ones that matter — which is itself a study pass. The tax is gone; the method finally gets a fair trial.
