Organizing Cards into Decks

Use TARGET DECK: to specify which deck cards should sync to:

TARGET DECK: Spanish Vocabulary

Q: How do you say "hello" in Spanish?
A: Hola

Q: How do you say "goodbye" in Spanish?
A: Adiós

TARGET DECK: French Vocabulary

Q: How do you say "hello" in French?
A: Bonjour

• Cards after a TARGET DECK: line sync to that deck
• You can use multiple TARGET DECK: directives in one file
• Cards before any TARGET DECK: use the default deck from settings
• Decks are created automatically if they don't exist

3. Sync to Space

Either:

• Click the cloud icon in the left ribbon
• Run the command "Sync all flashcards to Space" (Ctrl/Cmd + P)
• Use "Sync current file to Space" for a single file

4. Study in Space

Open the Space app on any device to study your flashcards with spaced repetition.

How Tracking Works

After syncing, the plugin adds a tracking comment after each card:

Q: What is the capital of France?
A: Paris
<!-- space-id: cktx1234abcd -->

This allows you to:

• Edit cards freely - changing the question or answer updates the existing card
• Move cards between files - the tracking stays with the card
• See sync status - cards without comments haven't been synced yet

Tip: Don't delete the <!-- space-id: ... --> comments unless you want to create a new card in Space.

FAQ

Can I sync to multiple decks?

Yes! Use the TARGET DECK: directive to specify which deck cards should sync to. See Organizing Cards into Decks for details.

What happens if I delete a card in Obsidian?

The card remains in Space. To delete it from Space, use the Space app directly.

Can I sync cards from Space back to Obsidian?

No, this is a one-way sync (Obsidian → Space). Obsidian is the source of truth.

Does it work with other flashcard formats?

Currently only Q: / A: format is supported. More formats (like :: syntax, cloze deletions) are planned.
