Clutio

• Smarter than a dictionary: polysemy, idioms, technical jargon resolved in context
• Effortless vocabulary: reading builds your word list automatically
• Cloze quizzes from your own reading — words stick because you met them in real context
• Fully local: search history and vocabulary never leave your device

🚀 Core Features 1. Context-aware AI translation — select a word and the owl button appears; or use the right-click menu or a shortcut (Alt+S · Mac ⌃S). Reads the surrounding sentence and page, then gives the meaning right here alongside the general one 2. 🔊 Pronunciation (TTS) — one click from the popup, your vocabulary list, or a review card 3. Automatic vocabulary & review — every lookup is saved with its context → cloze, multiple-choice and type-to-recall quizzes, a full-screen review tab (Alt+R · Mac ⌃R), a dashboard with activity heatmap, due count and streak, plus PDF / CSV export 4. 🖍 Saved-word highlighting — words you already saved are marked as you read; hover for meaning and pronunciation (no AI call) 5. 🔥 Streak tiers — 6 levels (Spark → Cosmic), layered motion effects as you stay consistent 6. Three AI engines — Groq (free and ultra-fast) / ChatGPT / Claude, BYOK
