Language immersion extension · Fluidity family
Everything you watch and read can teach you something
Follow a word from an authentic sentence to a saved context and local review, across videos, articles and your reading library.
Understand in the moment
Replay a line, click an unfamiliar word or translate one sentence. Move from watching to reading with the same vocabulary tools. Familiarity marks help you focus attention, while frequency and approximate familiar-word estimates add perspective.
Return to what matters
Keep the expression, preserve its source, and revisit it in Kept or guest Review. Resume a saved text or listen with read-along. Choose optional family tools when you want deeper exploration. Subtitle availability, language coverage and account permissions define what is available.
