## What is ReadUnbound?

Love reading, but finding dense books, complex foreign literature, or heavy technical documents an exhausting chore?

Most learning apps keep you trapped matching pictures to basic words. ReadUnbound is engineered for serious readers—whether you are an intermediate-to-advanced language learner (A2 to C1), a test-taker preparing for high-stakes exams, or a professional (lawyer, medical student, researcher) navigating dense jargon without dictionary fatigue.

Powered by Second Language Acquisition (SLA) science and adaptive AI, ReadUnbound turns reading into effortless vocabulary mastery. Read compelling stories calibrated precisely to your reading level, import your own documents, tap unfamiliar words to harvest them instantly, and let our intelligent Daily Flow guide you to total mastery.

TRANSPARENT AI INTEGRATION
ReadUnbound uses AI to craft contextual stories, breakdowns, and exercises. Browse pre-cached content for free. For real-time lookups and custom docs, bring your own API key (OpenAI, Gemini, Anthropic) or upgrade to Pro for zero-setup access.

WHY READUNBOUND IS DIFFERENT

1. READ WHAT YOU LOVE & IMPORT YOUR OWN
Skip generic textbook dialogues. Read adapted world literature across CEFR levels, or import your own materials:
• Curated Excerpts: 180–220 word reads across Sci-Fi, Business, Law, Medicine, and Classics.
• Text Import: Import papers or legal briefs to target specialized terminology.
• 1-Tap Harvesting: Tap any word for instant, level-appropriate definitions and add it directly to review.

2. DEEP LEXICAL ANALYSIS & ANATOMY
Move beyond static flashcards:
• Select-to-Explain: Highlight any phrase or sentence for full-sentence meaning plus word-by-word syntactic breakdowns.
• Compare Words: Deconstruct subtle differences between synonyms.
• Word Anatomy: Definitions, real-world examples, Latin roots, CJK radical decomposition.

3. 3-TIER SRS
Strengthen recall through progressive exercises and spaced repetition.
• Tier 1 Receptive: basic recognition
• Tier 2 Structural: reinforce word form and structure
• Tier 3 Productive: construct original sentences, graded by AI.

4. CRAM MODES & TARGETED DRILLS
• Exam Prep: Targeted sprints for SAT, GRE, GMAT, TOEFL, IELTS, USMLE, and Bar Exam.
• Weak-Point Recovery: Clear bottlenecks with rapid 1–3 minute micro-drills.

5. PREDICTIVE FLUENCY INSIGHTS
• Linguistic Velocity: Track words moving from recognition to active production.
• Recall Latency: Measure retrieval speed down to the millisecond.

6. 70+ LANGUAGES & ADAPTIVE SCAFFOLDING
• L2 Immersion: Target-language definitions for direct immersion.
• L1 Scaffolding: Toggle native-language previews whenever you need quick clarity.

FAIR MONETIZATION:
• Pro Subscription: Unlimited AI, all-inclusive, zero setup.
• Lifetime Pass (BYOK): Pay once, own the app forever. Use your own OpenAI, Gemini, or Anthropic API key with zero AI markup.
• Free: Core spaced repetition, curated excerpts, and quick-paste sampling.
