Xylingo: AI English Vocabulary Builder av Xylingo

Add any English word from any website, YouTube video, article, or e-book, PDF — and Xylingo builds your entire learning environment around it. Real news gets rewritten to include your words. AI characters use them in natural conversation. Tests target exactly what you're learning. No flashcards. No drilling. Just English that surrounds you until it sticks.

Xylingo is both a Firefox addon and a full learning app, designed for students, professionals, and anyone who wants to speak English naturally — without constant mental translation from their native language.

HOW IT WORKS

Every word you add follows a complete learning cycle: you save it — it appears in rewritten news — an AI character uses it in conversation with you — a targeted test checks your retention — the cycle reinforces until the word is truly yours.

FEATURES

Integrated English dictionary — click any unfamiliar word on any website, video, or article or pdf to save it instantly. Xylingo immediately generates personalized examples and learning materials around it.

Adaptive news feed — real news articles are automatically rewritten on the fly to include the exact words you are currently learning. You absorb vocabulary through daily reading, in real context, without extra study time.

Contextual AI chats — have realistic conversations with AI characters who naturally introduce and test your target words in dialogue. No rigid scripts, no artificial exercises — just conversation that feels genuine.

Native speaker formulation — write a thought in your native language and Xylingo identifies where your phrasing would sound unnatural in English. It explains how a native speaker would say the same thing, gives you the natural version, and follows up with practice tasks. This is how you stop translating and start thinking in English.

Interactive tests and exercises — targeted drills check retention and build confidence in real usage, not just recognition.

Personalized English environment — your vocabulary appears across rewritten news, chat prompts, and training sessions, creating a consistent immersive loop around the specific words you need.

Seamless Firefox integration — works across all websites. Click any word anywhere to begin a tailored learning process immediately.

WHO IT IS FOR

— Non-native English speakers at intermediate to advanced level
— Professionals who need precise, natural business English
— Students preparing for IELTS, TOEFL, or academic writing
— Anyone tired of apps that teach words in isolation and forget them by tomorrow

Xylingo does not ask you to set aside study time. It turns the browsing you already do into an English learning engine — one word at a time, in context, until English feels natural rather than studied.
