Flat vocabulary lists lose the reason the word mattered
Learners often save a word because it felt useful in a specific moment. Then the word gets exported into a detached list and the original meaning signal disappears.
That is why TubeLingo's vocab product direction is strong:
- save the original sentence
- save the source video
- track encounter count
The learner is no longer reviewing a random database entry. They are reviewing a piece of language that already appeared in real input.
Repetition should be visible
Encounter count is underrated. Seeing that a word appeared three or five times changes how learners judge importance. It tells them this is not just an interesting word. It is a recurring one.
