Why install Voiko?
Most people skip words they don't know. Voiko makes looking up a word effortless — no new tab, no dictionary app, no interruption to your reading flow. You learn the word in context, which is how vocabulary actually sticks.
Built for non-native English readers
Voiko is designed for people reading English as a second language. Every explanation is adapted to your native language and English level — beginner, intermediate, or advanced.
Your personal word history
Every word you look up is saved to My Words — a searchable vocabulary list you can review, filter by notes, and export to Notion or Obsidian.
