inContext is a free Chrome extension that acts as an AI dictionary for language learners. Highlight any unfamiliar word on any web page and it instantly returns a definition written for your current language level and shaped by the surrounding sentence, then stores everything in a side panel for later review.
Highlight any word on any page and inContext immediately shows its meaning without leaving the article, PDF or website you are reading.
The extension reads the surrounding sentence to choose the sense of the word that actually fits, rather than returning a generic entry.
Explanations are pitched at your language level, so the definition itself uses words you already understand.
Every looked-up word, plus the sentence you found it in, is stored in the side panel for later revision.
