Xoul Dictionary: Instant Definitions & Context-Aware Learning 📚✨ Master English vocabulary effortlessly while you browse the web. Xoul Dictionary is your AI-powered reading companion that provides instant English definitions, translations, and pronunciation with a simple double-click. Save looked-up words to your history, then revisit them in the new Review & Test tab. 🚀 Designed for English learners, students, and avid readers, Xoul Dictionary goes beyond simple definitions by analyzing the full sentence context, helping you understand how English words and phrases are actually used. 🌟 KEY FEATURES 👆 Instant Lookup Anywhere Double-click any English word on any webpage to see its definition instantly. Works seamlessly across regular web pages, complex web apps like Notion, and even PDF documents.

Enable the interactive subtitle mode directly from the YouTube or Netflix video player to click any word in the subtitles and see its definition instantly. 🧠 AI-Powered Context Analysis Unlike traditional dictionaries, Xoul uses advanced AI to understand the surrounding text. It intelligently detects idioms, phrasal verbs, and collocations (e.g., recognizing "figure out" instead of just "figure") and provides the precise definition for that specific context. 🗣️ Audio Pronunciation Listen to the correct pronunciation of words with a single click. Perfect for improving your listening and speaking skills. 🌍 Korean & Japanese Translation Look up English words and get definitions with optional translations into Korean or Japanese. The entire interface is also fully localized: • 🇺🇸 English • 🇰🇷 Korean (한국어) • 🇯🇵 Japanese (日本語) ☁️ Cloud Sync & History Your vocabulary history follows you everywhere.
