MemMaster — Spaced Repetition

MemMaster — Spaced Repetition for Obsidian

A simple yet powerful spaced repetition plugin that helps you memorize your Obsidian notes using proven learning techniques.

Features

• Turn any note into a flashcard — by tag or folder
• Review list — shows all cards due for review today, sorted by urgency
• Difficulty rating — mark cards as Easy, Medium, or Hard
• Smart scheduling — calculates optimal review intervals automatically
• Keyboard shortcuts — quick review without leaving the keyboard
• Multilingual — multiple language support

How It Works

1. Mark a note as a flashcard (via command or by adding a tag/moving to folder)
2. The plugin adds metadata to track your progress
3. Review cards when they're due — rate difficulty after each review
4. Cards are rescheduled based on your rating:
   • Easy → longer interval (2^stage days)
   • Medium → moderate interval (1.5^stage days)
   • Hard → shorter interval (1.2^stage days)
5. After 10 successful reviews, the card is considered "mastered" and removed from rotation

Algorithm

This plugin uses a simplified version of the SM-2 (SuperMemo 2) algorithm. Unlike the original, it doesn't use an "ease factor" coefficient — instead, fixed base values are applied for each difficulty level, making the system more predictable and easier to understand.

Installation

1. Open Settings → Community plugins in Obsidian
2. Click Browse and search for "MemMaster"
3. Click Install, then Enable
4. Configure your preferred flashcard source (tag or folder) in plugin settings
