Language Learning Spaced Repetition Flashcard Scheduler
Overview
A professional-grade, browser-based flashcard application designed for language learners. This tool facilitates active recall and spaced repetition (SRS) in a clean, distraction-free environment. Built for performance and accessibility, it operates entirely in-memory.
Core Features
- SRS Engine: A robust Leitner-inspired queue system for scheduling reviews.
- Deck Management: Create, rename, and organize multiple card sets (e.g., 'Spanish Core 1000', 'Japanese Kanji').
- Import/Export: Support for CSV and JSON file formats to ensure study data persistence (since local storage is disabled).
- Active Recall Interface: A card-flip interaction that prompts the user to guess the term before revealing the answer.
- Session Statistics: Real-time feedback on current study session performance (cards reviewed, accuracy rate).
UI/UX Design
- Aesthetic: A premium 'SaaS' look with a high-contrast, light-mode palette.
- Primary Background:
#ffffff - Surface/Card:
#f8fafc - Text:
#1e293b - Accents:
#4f46e5(Primary Indigo) and#10b981(Success Green)
- Primary Background:
- Animations: Smooth CSS transitions for card flips (transform: rotateY) and gentle slide-in effects for UI modules. No jarring layouts.
- Layout:
- Sidebar: Navigation and deck management controls.
- Main Area: Focused flashcard display with progress indicators.
- Dashboard: A clean summary view of the currently loaded deck.
Technical Implementation
- Architecture: Single-file HTML5 with embedded CSS and Vanilla JavaScript.
- State Management: All application state (decks, current card index, SRS buckets) stored in a single JavaScript object (
window.appState). - Constraints Compliance:
- NO Storage: No
localStorage,sessionStorage, or IndexedDB. All data is transient. - Sandboxed Compatibility: Designed to function within a sandboxed
iframewith no parent-window communication. - Performance: Use
requestAnimationFramefor smooth card transitions.
- NO Storage: No
Developer Directives
- Vanilla JS Only: No build steps. Use ES6+ features natively.
- CDN Assets: Utilize Tailwind CSS via CDN for styling and a lightweight icon library (e.g., Phosphor Icons or Heroicons) for iconography.
- Accessibility: Ensure all interactive elements have proper
aria-labelsand keyboard navigation (space bar to flip, arrow keys for selection). - Modals: Use absolute-positioned CSS containers for all alerts/prompts. Do not use standard browser
alert()orconfirm()functions.

Frequently Asked Questions
Everything you need to know about using this application.
What is the spaced repetition method used in this app?
This application utilizes the Leitner system, a scientifically proven method where flashcards are reviewed at increasing intervals. Cards you answer correctly move to buckets with longer delay periods, while cards you struggle with are reviewed more frequently to ensure deeper long-term retention of new vocabulary. By leveraging this active recall technique, the scheduler ensures that your study sessions focus on the specific words you find difficult, maximizing your learning efficiency and reducing time spent on vocabulary you have already mastered.
Can I save my flashcard decks within the browser?
To ensure maximum privacy and compatibility with sandboxed browser environments, this tool does not store your progress in persistent storage like cookies or local storage. All your data resides strictly in your computer's temporary memory. Because of this, you should use the integrated 'Export to CSV' or 'Save JSON' feature frequently. This allows you to download your current study deck to your device and import it back into the tool whenever you return to continue your practice sessions.
How do I manage multiple language decks?
The interface includes a robust deck management system that allows you to categorize cards by language, proficiency level, or topic. You can create as many unique decks as your memory allows and toggle between them using the sidebar navigation menu. Each deck maintains its own individual SRS statistics, so your progress in one language—such as Spanish or Japanese—remains distinct from your progress in another, allowing for structured and organized multilingual study habits.
Is this flashcard scheduler mobile responsive?
Yes, the application is built using a mobile-first design strategy, ensuring that the interface adapts fluidly to smartphones, tablets, and desktop screens. All buttons, flashcards, and navigation elements are touch-friendly and optimized for smaller screens. Whether you are studying on the go using your phone or sitting down for a deep-focus session on a desktop monitor, the layout adjusts automatically to provide a consistent, distraction-free environment that promotes concentration and learning.
