About Sensei on my Side

🏆 "Dreaming of reading global news in English effortlessly every morning?" 📈 "Want to train your English skills using daily real-world news articles?" Eiko-sensei is here to make that dream a reality! 🎓✨ Open your browser side panel, and your personal AI language coach Eiko (英子) is always sitting right on your side ("Yokoie" / 横居)! Since she is powered by Chrome's built-in local AI engine, Gemini Nano, all processing runs entirely on your own device. 100% offline, private, secure, and completely free AND OPEN SOURCE! 🔒💻 --- 🚀 Key Features 1️⃣ One-Click Turn Webpages into Lessons! 📰 Simply click "Coach Me" on any English article. Eiko-sensei instantly generates a step-by-step curriculum: Article Summary ➡️ Vocabulary Breakdown ➡️ Key Idiomatic Phrases ➡️ Reading Comprehension Quiz! 2️⃣ RPG-Style Avatar Leveling System 🎒➡️🧙‍♂️ Set your target TOEIC score (500 to 900+). Eiko-sensei's pixel-art avatar dynamically evolves from a rookie "Chibi Student 🎒" into a "Business Consultant 💼" and ultimately a "Pristine Wizard 🧙‍♂️✨"! 3️⃣ Smart Active Recall Study Deck 🗂️ All vocabulary items generated during lessons are automatically saved into a study card deck. Every card keeps track of its origin URL so you can jump back to the source article with one click. 4️⃣ Contextual Highlighting Dictionary 🔍 Highlight 1-3 words on any page and right-click to instantly look up definition keys, relevant business synonyms, and 2 target TOEIC-style example sentences. 5️⃣ Interactive Contextual Q&A 💬 Confused by a phrase or sentence? Directly ask Eiko-sensei in the sidebar chat. Watch her dynamic emoji states shift (thinking/sweating 💭💦 to happy sparkles ✨🎉) as she replies natively in Japanese or your preference! --- ⚙️ Prerequisites (How to download Gemini Nano locally) Because this extension runs 100% offline, you need to enable and download Gemini Nano in Chrome: 1. Enable Chrome Flags at chrome://flags: - #optimization-guide-on-device-model ➡️ Set to Enabled BypassPrefRequirement - #prompt-api-for-gemini-nano ➡️ Set to Enabled - Relaunch Chrome. 2. Force the component download via DevTools console (F12 on any page): - Run: await ai.languageModel.create(); 3.
