Flashcard Generation
Kindle: No flashcards. No study tools. No spaced repetition.
Aeion Manuscript: AI-generated flashcards with spaced repetition, created directly from selected text — front is the question or key term, back is the answer or definition.
Generated Flashcards:
typescript
{
"flashcards": [
{ "front": "Who is the protagonist?", "back": "Jay Gatsby" },
{ "front": "What does Gatsby do for a living?", "back": "Bootlegging during Prohibition" },
{ "front": "Where does Gatsby live?", "back": "West Egg, Long Island" },
{ "front": "What is Gatsby's ultimate goal?", "back": "Reunite with Daisy" }
]
}
Spaced Repetition:
Review intervals: new terms come up again after 1 day, terms you're still learning after 3 days, and mastered terms after 7 days to confirm retention. A correct answer lengthens the interval; a wrong answer resets it to "new" — all scheduled automatically.
typescript
interface VocabularyEntry {
word: string;
definition: string;
mastery: "new" | "learning" | "mastered";
nextReviewAt?: string;
reviewCount: number;
}
Vocabulary with Definitions:
Selecting text can also extract key vocabulary with a plain-language definition for each term.
// Output:
// { word: "protagonist", definition: "The main character of a story" }
// { word: "ostentatious", definition: "Vulgar or pretentious display" }
Study Guide Generation
Kindle: No study guides. No discussion questions. No important quotes.
Aeion Manuscript: AI-generated study guides — key concepts, discussion questions, and important quotes with chapter references — created for an entire book in one pass:
typescript
interface StudyGuide {
key_concepts: string[];
discussion_questions: string[];
important_quotes: string[];
}
Generated Study Guide:
typescript
{
"key_concepts": [
"The American Dream and its corruption",
"Social class conflict (old money vs new money)",
"The past's influence on the present",
"Symbolism of the green light",
"Hollowness of upper-class society"
],
"discussion_questions": [
"How does Gatsby's wealth affect his identity?",
"What is the significance of the novel's title?",
"How does Fitzgerald portray class differences?",
"What role does geography play in the novel?",
"How does the novel critique the American Dream?"
],
"important_quotes": [
{ "quote": "So we beat on, boats against the current...", "source": "Ch. 9" },
{ "quote": "I hope she'll be a fool—a beautiful little fool.", "source": "Ch. 1, Daisy" }
]
}

Reading Goals & Analytics
Kindle: Basic reading progress. No goals. No streaks. No analytics.
Aeion Manuscript: Full reading goal tracking and analytics:
typescript
interface GoalProgress {
bookId: string;
goalType: "chapters" | "pages" | "minutes" | "days";
target: number;
current: number;
percentComplete: number;
onTrack: boolean;
daysRemaining: number;
requiredDailyRate: number;
}
A goal is considered on-track when progress is within 10% of the expected pace for the time elapsed, and the required daily rate shows exactly how much reading is needed per day to finish on schedule.
Reading Statistics:
typescript
interface ReadingStats {
totalBooks: number;
booksCompleted: number;
totalPagesRead: number;
totalReadingTime: number; // minutes
averageSessionLength: number;
favoriteGenres: string[];
streakDays: number;
currentStreak: number;
}
On-Track Indicator:
Target: 9 chapters in 14 days
Day 5: Completed 3 chapters (21% complete)
Expected: ~32% complete
Status: BEHIND (need 0.5 chapters/day to catch up)
Platform Integration
Kindle: Standalone device and app. No platform integration. No API.
Aeion Manuscript: Native to Aeion OS via the platform's event bus. Reading progress flows automatically to other modules — CRM logs the reading activity against the customer record, and Notifications celebrates when a reader finishes a book — with zero API keys, manual imports, or custom integration work required.
No API keys. No manual sync. Automatic.
