Clutio - AI Vocabulary Builder

Tracking since Apr 1, 2026.

Changelog

• Jun 9, 2026
  description

  Click any word, AI explains it in context. Auto-saves to your vocabulary, builds cloze quizzes, native pronunciation. Free.
  
  ───────────────────────────────────────
  
  Dictionaries list definitions. Google Translate flattens sentences. Clutio reads the surrounding sentence and the whole page, then tells you what the word means *right here, right now* — with nuance, example sentences, native pronunciation, and translation, in place.
  
  Every looked-up word is auto-saved to your vocabulary, and review quizzes are generated from the actual sentences you read — so reading *is* studying.
  
  No account. No server. Your vocabulary stays in your browser. The core experience is free on Groq's daily quota (14,400 requests/day with Llama 3.1 8B — ultra-fast inference).
  
  ✅ Why 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 — TOEFL / IELTS / GRE / SAT-style retention
  - Fully local: search history and vocabulary never leave your device
  
  🚀 Core Features

  2. 🔊 Native pronunciation (TTS) — hear the word with one click (v1.4.0)
  3. Floating owl quick-translate button — appears on selection
  4. Auto vocabulary + cloze & multiple-choice quizzes — PDF / CSV export
  5. 🔥 Streak tiers (v1.4.1) — 6 levels (Spark → Cosmic), layered motion effects as you stay consistent
  6. Three AI engines — Groq (Llama / Qwen / GPT-OSS, free) / ChatGPT / Claude, BYOK
  
  🎯 Made For
  - Students prepping TOEFL, IELTS, GRE, SAT, Cambridge — learn words in context, not in flashcard isolation
  - Developers & researchers reading English docs, papers, GitHub, Stack Overflow in a non-native language
