BookApp doesn't.\n\n**Read · Remember · Act** — the core loop\n([design doc](docs/redesign-read-remember-act.md)):\n\n- **Read.** A summary-first catalog of original \"The Big Ideas in …\" editions of\n  major non-fiction (~15 min each, legally-safe clean-room prose with attribution),\n  alongside everything you import yourself.\n- **Remember.** Every book becomes a deck of swipeable knowledge cards — one idea\n  per card, gradient-coded by kind (Principle, Mental Model, Habit…). Save the\n  keepers; they live in the Saved tab with your learnings and highlights.\n- **Act.** Every book becomes a 14-day implementation plan. Check steps off\n  in-app, or export them — practice sessions to your Calendar (write-only),\n  to-dos to Reminders.\n\nAnd the original toolkit still applies to all of it:\n\n- **Elastic length.** Compress a 400-page treatise into a 20-page summary that keeps the author's voice. Or expand a five-page essay into a chapter. The model preserves tone, structure and key arguments.\n- **Listen on-device.** Every book becomes an audiobook with the system's premium voices. The current word lights up as it's spoken; the page flips itself.\n- **Speed-read three ways.** Paragraph + word highlighting, single-word focus, or Spritz-style RSVP at any pace from 150 to 1,200 wpm.\n- **Re-style.** Make a dense academic chapter sound more like Joan Didion. Strip references to a theme you don't care about.\n- **Pull key learnings.** 5 to 15 takeaways per book in seconds. Edit, star, export.\n- **Yours.** Books in your iCloud Drive. Anthropic API key in your Keychain. No backend.\n\n## Setup\n\n```bash\nbrew install xcodegen\ncd /Users/lukadadiani/Documents/book-app\nxcodegen generate\nopen BookApp.xcodeproj\n```\n\nIn Xcode, set your **Team** under *Signing \u0026 Capabilities* and choose a unique\nbundle id. Build and run on **iPhone 17 Pro** (or any iOS 18+ simulator).\n\nOn first launch:\n\n1. Open *Settings → AI* and paste your Anthropic API key. It's stored in the\n   iOS Keychain — never on disk in plain text, never in the project.\n2. Tap **Import a book** on the home screen and pick an `.epub` or `.pdf`\n   from iCloud Drive.\n\nGet a Claude API key at \u003chttps://console.anthropic.com/\u003e.\n\n## Tech\n\n| Layer | Choice |\n|---|---|\n| UI | SwiftUI on iOS 18+ / iPadOS 18+ |\n| Persistence | SwiftData with private CloudKit sync |\n| EPUB | In-house parser over `ReadiumZIPFoundation` |\n| PDF | PDFKit |\n| TTS | `AVSpeechSynthesizer` with word-range highlighting |\n| Local LLM | Apple Foundation Models (with MLX-Swift fallback hook) |\n| Cloud LLM | Claude Sonnet 4.6 / Opus 4.7 via Anthropic Messages API + ephemeral prompt caching |\n\nSee [docs/architecture.md](docs/architecture.md) for the full picture.\n\n## Topics\n\n`ios` · `swiftui` · `ipados` · `swiftdata` · `cloudkit` · `epub-reader` ·\n`pdf-reader` · `text-to-speech` · `speed-reading` · `claude-api` ·\n`anthropic` · `apple-foundation-models` · `book-summarizer` · `rsvp`\n\n## License\n\nPersonal-use license.
