One click saves it to your personal dictionary. When you're ready to review, open the Flashcards tab and let spaced repetition do the rest. No account. No internet needed for review. Everything stored privately in your browser. ✨ KEY FEATURES 📖 Instant Translation While Browsing Hover over any word or highlight any phrase on any website to see an instant translation. Supports two interaction modes: hover (cursor over a word) and select (highlight text). Perfect for reading articles, news, and any foreign-language content without breaking your flow. 💾 Save Words in One Click See a word you want to remember? Hit Save and it goes straight to your personal vocabulary dictionary. Save individual words or short phrases (up to 3 words) directly from the translation popup — no copy-pasting, no switching tabs. 🧠 Spaced Repetition Flashcards Your saved words automatically become flashcards.
