Why Lampio is different

Three ways it turns reading into learning

In a page full of English, only the words worth learning light up
Words you already know fade into the background; the unfamiliar ones light up — your attention is never drowned by what you already know.
Remember a word in the very sentence you met it
Saved words return for review inside the original sentence you met them in — not stranded on a flashcard. Memory holds when it has a hook.
Your vocabulary is the road you've read
Every word remembers the article and sentence where you first met it. This isn't a dictionary — it's the trail of your English.

CEFR difficulty highlighting · double-click lookup · in-context review (SM-2) · bilingual translation · cross-device sync — quietly working underneath.
