The method
Why it works
Context makes words stick.
Context
A word on a flashcard doesn't stick the same way as a word you read mid-story. Context isn't decoration — it's how memory works. Lira saves every word alongside the sentence where you found it.
The FSRS Algorithm
Forgetting follows a predictable curve. FSRS tracks it for every word you save. You end up reviewing less and keeping more.
Active immersion
Fill-in-the-blank exercises keep you busy. Reading makes you think. The difference in what sticks is real. Lira is built around reading because that's where acquisition happens.

Contextual anchoring
Every word fits into a network of meaning.
The brain does not store words as lists. It connects them to contexts, emotions, and semantic families. Lira memorises every word in the exact sentence where you encountered it, so the network builds naturally.
Everything you need, nothing in the way.
No streaks, no hearts, no mini-games. Just reading, memory, and an algorithm you can trust.
