Usage

obsidianki                   # Generate flashcards
oki                          # Alias

Configuration

oki config                         # Show config
oki config get max_cards           # Get specific setting
oki config set max_cards 15        # Update setting
oki config set model "GPT-5"       # Switch AI model

Tags

oki tag                      # Show tags
oki tag add python 2.0       # Add/update tag weight
oki tag remove python        # Remove tag weight
oki tag exclude boring       # Exclude notes with 'boring' tag
oki tag include boring       # Remove 'boring' from exclusion list

Notes

# Process specific number of notes
oki --notes 5                         # Sample 5 random notes
oki --notes 10 --cards 20             # Sample 10 notes, max 20 cards total

# Process specific notes by name
oki --notes "React" "JavaScript"       # Process specific notes
oki --notes "React" --cards 6          # Process React note, max 6 cards

# Directory patterns with sampling
oki --notes "frontend/*"               # Process all notes in frontend/
oki --notes "frontend/*:5"             # Sample 5 notes from frontend/
oki --notes "docs/*.md:3"              # Sample 3 markdown files from docs/
oki --notes "react*:2" "vue*:1"        # Sample 2 React + 1 Vue note

# Mixed usage
oki --notes "React Hooks" "components/*:3"  # Specific note + 3 from pattern

Query mode

# Make flashcard without source note
oki -q "how to center a div"
oki -q "CSS flexbox" --cards 8

# Targeted extraction from source note(s)
oki --notes "React" -q "error handling"
oki --notes "JavaScript" "TypeScript" -q "async patterns" --cards 6

Advanced

# Deck management
oki --deck "Programming"             # Add cards to specific deck
oki deck                             # List all Anki decks
oki deck rename "Old" "New"          # Rename a deck

# History
oki history stats                    # View generation statistics
oki history clear                    # Clear processing history
oki history clear --notes "React*"   # Clear history for specific notes

# Templating
oki template add "programming" "--notes 'frontend/*' --cards 3' -b 1"
oki template use programming # runs the above command as "oki --notes 'frontend/*' --cards 3' -b 1"

How it works

Standard mode

1. Finds old notes in your vault (configurable age threshold)
2. Weights notes by tags and processing history (avoids over-processed notes)
3. Generates flashcards using Claude 4 Sonnet
4. Creates cards in Anki "Obsidian" deck (or DECK set in config)

Query mode

• Standalone: Generates flashcards from AI knowledge alone based on your query
• Targeted: Extracts specific information from selected notes based on your query

MCP

There is an experimental MCP server that runs Obsidianki as a subprocess. Useful if you want to generate flashcards from daily use with an LLM, such as if you ask questions back and forth and want to generate flashcards from that material.
