Flashcard Desktop

A cross-platform desktop flashcard application with spaced repetition scheduling (SRS). Built with Electron and React, it integrates seamlessly with Obsidian vaults by storing flashcards as markdown files.

Features

• Spaced Repetition Algorithm: SM2-like scheduling with customizable ease and interval settings
• Multiple Card Formats:
  • Multi-line cards using ? (or ?? for bidirectional)
  • Inline cards using :: (or ::: for bidirectional)
  • Cloze deletions with ==highlighted== or {{curly}} syntax
• Obsidian Integration: Works directly with your Obsidian vault - no data migration needed
• File Watching: Auto-syncs when markdown files change externally
• Keyboard-First Design: Space to flip cards, 1-4 for responses, Escape to exit
• Statistics Tracking: Monitor your review progress and scheduling

Card Format Examples

Multi-line card:

What is the capital of France?
?
Paris

Inline card:

Capital of France::Paris

Cloze deletion:

The capital of France is ==Paris==.

How It Works

1. Select your Obsidian vault folder
2. The app scans for markdown files and extracts flashcards
3. Files are grouped by folder into "decks"
4. Cards are filtered by due date for review
5. Your responses update scheduling metadata directly in the markdown files

Scheduling data is stored inline as HTML comments:

What is 2+2?
?
4
