Learning Sessions
Learning Sessions are available on the PRO plan.
Echo's Learning Sessions turn passive listening into active mastery. Every word you save from the transcript player becomes a card in your personal review deck.
- Daily word review — work through your saved words with flashcard, multiple-choice, and fill-in-the-blank exercises.
- Spaced Repetition (SRS) — the SM-2 algorithm schedules reviews so you see words just before you would forget them.
- Session length — configure how many words you review per session (10–30).
- Streak tracking & leaderboard — daily study streaks keep you consistent; the optional public leaderboard lets you compete with other learners.
