Learn your target language by reading the web.
Contexto quietly swaps a few familiar words on any page for words in your target language, so you absorb it in context as you read.
Try it on this page.
Keep scrolling and the dial rises on its own. Grab it any time to set your own level, then hover any underlined word.
Live target-language density demo
You did not learn your first language from flashcards. You learned it out in the world, meeting each new word wrapped in a sentence you already understood, and guessing the rest. That quiet inference, repeated a thousand times, is how fluency is built. Contexto brings the same immersion to the pages you already read, a few words at a time, in your target language, in context.
This is the actual extension behavior: a dial from your reading to gentle immersion. And yes, the first word to turn is where the name came from.
The idea
How people actually learn a target language
Drills teach you about the language.
Classes, flashcards, and quizzes build knowledge of rules. Fluency grows differently: you meet new words in sentences you mostly understand, then use the surrounding words to figure them out.
You already do this.
You learned your first language this way, and you still guess unfamiliar words from their surroundings every day. Contexto simply points that same instinct at your target language.
Immersion, without moving abroad.
You can't always live in Madrid (womp womp), but you already read for hours a day. Contexto turns that ordinary reading into gentle, dosed immersion, a few words at a time.

Questions
Frequently asked
Is it free?
yuh
Does my reading leave my device?
No. Contexto runs entirely offline; it never sends page text, browsing history, or translations to any server. See the privacy page.
Can I choose my target language?
Yep. Pick your target language in the extension and switch any time. If yours is not there yet, DM me on LinkedIn :)
How is this different from flashcards?
Flashcards quiz you out of context; Contexto teaches in context, the way immersion does, with no quizzes required (an optional review exists).
