That's why flashcards from a textbook don't stick — but a word from an article you actually read does. Contextale saves every word with the sentence, the page, the moment. Your brain does the rest.
Everything stays on your device. No accounts. No tracking.
Le président a souligné que les enjeux géopolitiques actuels nécessitent une réponse coordonnée de l'ensemble des partenaires européens. Cette déclaration intervient dans un contexte de tensions croissantes...
You've looked up "enjeux" before. Maybe twice. Maybe five times. It never stuck — because you saw it on a blank flashcard with no story around it.
But you still remember "serendipity" from that one article you read three years ago. You remember the paragraph, the argument, the feeling. That's not a coincidence — that's how memory works. Your brain doesn't store isolated facts. It stores experiences.
Contextale is built on this one principle: save the context, and the word saves itself.
Browse any website in any language. News, Wikipedia, blogs, forums, documentation — if it's text on the web, it works.
Select any word or phrase. Get an instant translation with the full sentence as context.
One click saves the word, translation, context sentence, and source URL to your personal dictionary.
Flashcards with SM-2 spaced repetition show you each word at the optimal time. Quiz mode keeps it active.
Translation is powered by Google Translate — it handles 100+ languages, works instantly, and doesn't require an API key. A direct request from your browser to Google. We never see the words you look up.
Not just a word and a translation. Every entry includes the sentence, the page title, and the URL. When you review it, you're back in the moment you learned it.
The same algorithm Anki uses. Each word shows up exactly when you're about to forget it. Science-backed, not vibes-based.
Multiple choice with keyboard shortcuts. Stuck? Hit Space for a context hint — the original sentence appears, and suddenly you remember.
Any website, any page, any language pair. News sites, Wikipedia, blogs, forums, documentation — if you can read it, you can learn from it.
All data lives in your browser's local storage. No accounts, no servers, no analytics. Your vocabulary is nobody's business.
Your data is yours. Export your entire dictionary as JSON anytime. Import it on another device. We're not holding your words hostage.
Every word carries the sentence, the page, and the source. When you review, you're not staring at a blank flashcard — you're back in the article.
You follow Le Monde, El País, or Die Zeit. You understand 90% — but that other 10% keeps slipping away.
Documentation, Stack Overflow threads, academic papers in other languages. Technical vocabulary, saved with technical context.
Reading your new country's news, government sites, local forums. Building practical vocabulary from real daily life.
All data lives on your device. No servers. No cloud. No one sees what you read or what you look up.
Optional password protection with auto-lock timer. Your dictionary, your business.
Your words are yours. Export to JSON whenever you want. No vendor lock-in, no subscriptions.
No "sign in with Google". No tracking pixels. Not even a cookie.
Switch between language pairs anytime. Powered by Google Translate — supports 100+ languages.
