I'm not sure I understand. From what I've seen in the video, the method is essentially:
- Find a word to learn.
- Search the web for example sentences that use that word (Jisho doesn't always have one).
- Generate your own listening exercises by running those sentences through text-to-speech (not knowing whether the result is correct, e.g. 辛い = つらい or からい?).
- Look up any grammar points on random websites (not knowing whether the information you find is applicable or correct).
- Make your own Anki deck based on the above.
Compared to following a textbook or other course:
- Learn the ready-made vocabulary list.
- Read the ready-made example text.
- Listen to the spoken version of the text as recorded by real people.
- Read the grammar explanation that follows the text.
- Use an existing Anki deck for the course you're following.
Can you explain in what way your method is easier and faster?
