Words arrive with their sentence
A word learned in isolation is harder to retrieve than a word learned in a sentence. Cards generated from your material keep the source sentence attached, so review shows the usage rather than a dictionary gloss.
Use case
Learning a language
Vocabulary is the classic case for spaced repetition, and it is also where most learners quit, because prebuilt decks are full of words they will never use. Building cards from material you are genuinely reading, an article, a chapter, a transcript, keeps the vocabulary tied to a context you already care about, and the source link means each word carries the sentence it appeared in. Scheduling with FSRS-6 spaces reviews around your own forgetting curve rather than a fixed interval ladder, which matters most for the middle band of words you almost know. Verbatim mode doubles as pronunciation and phrase drilling for set expressions.
Phrases and set expressions
Verbatim mode fades a phrase progressively until you can produce it from memory, which suits greetings, idioms and any expression where word order is not negotiable.
What it will not do
It is a recall tool, not a tutor. It does not correct your grammar, score your accent, or hold a conversation, and it is no substitute for speaking practice.
