## One-line summary

FluencyScore is a web and mobile app that teaches languages through reading real text. Word bubbles translate every word inline, native audio plays every sentence, and AI-powered quizzes test writing and vocabulary after each passage.

---

## The problem it solves

Traditional language apps (Duolingo, Babbel, Anki, etc.) teach vocabulary in isolation, through flashcards, drills, and multiple-choice questions. Users often study for months before they can understand a real sentence. FluencyScore reverses this: you read real content from day one, understanding as you go, and the language gets learned as a side effect of reading.

---

## Core learning pillars

FluencyScore covers all four pillars of language fluency in a single loop:

| Pillar | How FluencyScore handles it |
|--------|--------------------------|
| Comprehension (reading) | Word translation bubbles appear inline, no app switching, no dictionary |
| Writing & syntax | After every 12–20 sentences, user types full sentences from scratch |
| Pronunciation (listening) | High-fidelity native audio plays for every sentence |
| Vocabulary speed | Fast-paced matching games lock in word recognition after each block |

---

## The Reading Loop (one full session cycle)

```
[ GLANCE ]  →  [ LISTEN ]  →  [ TYPE ]  →  [ AI ADAPTATION ]
Word Bubbles   Native Audio   Full Syntax   Deep Personalization
```

1. **Read** a sentence in the target language
2. **Tap any word**: a translation bubble appears above it immediately
3. **Listen**: native audio plays so you absorb real rhythm and cadence
4. **Quiz (typing)**: build and type complete sentences from scratch
5. **Quiz (matching)**: fast pair-matching game locks in vocabulary
6. **AI adjusts**: the next content block adapts to what you struggled with
