Simple Flashcards

RemNote-style flashcards for Obsidian. Write cards inline in your notes with simple delimiters, then review them with optional spaced repetition.

Install

Copy main.js, manifest.json, and styles.css into <your-vault>/.obsidian/plugins/simple-flashcards/, then enable Simple Flashcards under Settings → Community plugins.

The ::: block — where cards live

Cards are only read inside a block. A bullet ending with ::: opens a block; each of its direct child bullets becomes a card if it contains a delimiter. Plain bullets, deeper-nested bullets, and anything outside a ::: block are ignored — so template files, LaTeX math, and ordinary prose are never mistaken for cards.

- French vocab :::
    - Capital of France :: Paris
    - el perro >> the dog
    - just a note to myself        <- no delimiter, ignored

Card delimiters

Syntax	Example	Result
:: basic	Capital of France :: Paris	front → back
>> forward	Question >> Answer	front → back
<< backward	Answer << Question	prompts from the right side
<> bidirectional	uno <> one	two cards, one each direction
{} cloze	The sky is {blue}	fill-in-the-blank
;; multiline	Planets ;;	answer is the bullet's own sub-bullets

Grouped clozes — number them so several blanks hide together as one card:

- Geography :::
    - {1|Paris} is the capital of {1|France}; {2|Berlin} is in Germany.

Multiline answer — the ;; bullet's children are its answer:

- Astronomy :::
    - Inner planets ;;
        - Mercury
        - Venus, Earth, Mars

Decks

Tag a card with #deck/Name to file it into a deck (nesting allowed: #deck/Spanish/Verbs). Put the tag on the ::: header to deck the whole block, on a single card line to deck just that card, or anywhere in the note as a default. Cards with no tag go to the Default deck. The deck prefix (deck) is configurable in settings.

Reviewing

Open the command palette and run any of:

• Review due cards (whole vault) — review everything that's due. Also on the ribbon (layers icon).
• Review a deck… — pick a deck from a list showing due/new counts.
• Review current note — review only this note's cards.
• Toggle inline review for current note — review in place: answers blur, click Reveal, then rate without leaving the note.

In the review modal: Show answer (or Space), then rate Again / Hard / Good / Easy (or keys 1–4). Suspend card removes it from rotation. If spaced repetition is turned off in settings, review is a plain flip-through.

Browsing & editing

• Browse all flashcards — a searchable list of every card with its deck, type, and status; click a row to jump to that line in the note.
• Right-click a card line for: review this card, reset schedule, suspend / unsuspend.

Spaced repetition

Scheduling uses the SM-2 algorithm. Intervals, ease, and due dates are stored in the plugin's own data.json — your notes are never modified. If you edit a card's text, the plugin fuzzy-matches it back to its original schedule so your progress isn't lost.

Settings

• Spaced repetition — enable/disable; tune starting ease, easy bonus, hard factor, and new-cards-per-session.
• Decks — change the deck tag prefix.
• Appearance — toggle live-preview styling of card delimiters.
• Card syntax — enable or disable each delimiter type individually.
