FluentU's 'progress bar' acts as both a measure of how much of that video (or audio) you've learned with FluentU, and also how many of its vocabulary words you already know before watching it.

A word can be considered 'already known' by FluentU two ways:

  • You clicked 'Already Known' on the word while using FluentU 
  • FluentU assumed you 'already knew' the word based on your language level settings 

If you click "Already Know" for a word, you can find it in your Already Known flashcard set by going to My Content.
