Clutio Ai Vocabulary Buil

Click any word, AI explains it in context. Auto-saves to your vocabulary, builds cloze quizzes, native pronunciation. Free.

───────────────────────────────────────

Dictionaries list definitions. Google Translate flattens sentences. Clutio reads the surrounding sentence and the whole page, then tells you what the word means *right here, right now* — with nuance, example sentences, native pronunciation, and translation, in place.

Every looked-up word is auto-saved to your vocabulary, and review quizzes are generated from the actual sentences you read — so reading *is* studying.

No account. No server. Your vocabulary stays in your browser. The core experience is free on Groq's daily quota (14,400 requests/day with Llama 3.1 8B — ultra-fast inference).
