Lexisy is more than a dictionary. It's a learning loop — look up, save, quiz, remember.

Translate on any webpage

Select any English word while browsing — see the meaning, pinyin, and word forms instantly without leaving the page. Powered by the offline CC-CEDICT dictionary with translation fallback.

Smart spaced reminders

Lexisy weighs your familiarity rating, view count, time since last seen, and recent quiz misses to resurface the words you most need. Rate familiarity 0–5 right from the notification.

Built-in quizzes

Two-choice quizzes from your saved words. Track your weekly and monthly accuracy as your vocabulary grows.

Tag and organize

Create custom tags for your favorites. Premium users get IELTS, TOEFL, and TOEIC word packs to get started.

Syncs across devices

Your favorites, history, and progress sync between the browser extension and the Android app via your account.
