ruu-lang

From reading to knowing — deep linguistic comprehension powered by AI.

ruu-lang (รู้) turns every webpage into an interactive language tutor. Rather than providing flat, word-for-word translations, ruu-lang deconstructs foreign text into deep linguistic context: clause structure, syntactic patterns, verb conjugations, functional particles, pragmatic register/tone, and root dictionary lemmas. KEY FEATURES: • Instant Selection Triggers: Highlight any text to pop the explanation card, show the floating "รู้" action badge, or use the keyboard shortcut (Cmd+Shift+E on Mac, Ctrl+Shift+E on Windows). • Modular Linguistic Analysis: - Overview & Nuance: Idiomatic translation, register (casual, polite, literary, slang), and cultural subtext. - Grammar & Structure: Clause architecture, syntax patterns, and conjugations. - Key Vocabulary: Itemized word-by-word breakdown with dictionary base lemmas. - Phonetics & Romanization: Optional Furigana/Romaji, Pinyin, IPA, or RTGS for non-Latin scripts. • Native Audio Pronunciation: One-click natural speech powered by your browser's on-device Web Speech engine. Press "R" while the card is open to instantly replay pronunciation. • Bring Your Own Key (BYOK): Full freedom over your AI models. Connect OpenRouter (Free tier default with no card needed), OpenAI (GPT-4o-mini, o3-mini), Anthropic Claude, Google Gemini, Groq, or local offline models via Ollama / LM Studio. • Privacy-First & Zero Telemetry: Your API keys and base URLs are stored strictly on your local device (chrome.storage.local) and never sent to our servers. UI renders inside a closed Shadow DOM for complete page isolation. HOW TO GET STARTED: 1. Install ruu-lang and pin it to your toolbar. 2. Open Settings and add your API key (defaults to OpenRouter's free tier with google/gemma-4-31b-it:free). 3. Highlight text on any website to see your instant linguistic breakdown!
