Flashcard Maker
Create flashcards with front and back sides, study them with flip, shuffle, and navigation, and keep decks saved in your browser. Import and export decks as JSON.
What the Flashcard Maker Does
The Flashcard Maker lets you build study decks in your browser. Type the question on the front, the answer on the back, and press Add Card. Every card appears in the deck list on the left, while the study panel on the right lets you flip your way through the deck one card at a time. You can move backward and forward, shuffle the order, and track your progress through the deck.
Decks are saved automatically in your browser's local storage, so they are still there when you come back, and nothing is uploaded to a server. You can also export a deck as a JSON file to back it up or share it, and import someone else's deck to study it yourself.
How to Use the Flashcard Maker
- Give your deck a name so you can recognize it later.
- Type the front of the card, such as a question or a term.
- Type the back of the card, such as the answer or the definition.
- Press Add Card. Repeat for as many cards as you need.
- Use the study panel to flip cards, move between them, and shuffle the order.
- Export the deck as JSON when you want a backup or want to share it.
Why Flashcards Work
Flashcards are built on active recall and spaced repetition, two of the most effective study techniques identified by cognitive science. Active recall means forcing your brain to retrieve an answer instead of passively re-reading it, which strengthens the memory far more than review alone. Spaced repetition means reviewing difficult cards more often and easy cards less often, so study time goes where it is needed most.
The forgetting curve explains why this matters. Without any review, most new information fades within days. Each successful recall interrupts that decay and extends how long you remember the material, so short daily sessions beat one long session before an exam.
Tips for Effective Cards
- One fact per card: a card that asks two things gives you no useful signal when you get it half right.
- Keep answers short: a single word or a short phrase forces precise recall.
- Use your own words: rewriting a definition in your own language is part of the learning.
- Add context: for languages, put the word in a sentence so you learn its usage along with its meaning.
- Fix weak cards: if you keep missing a card, the question is usually ambiguous. Edit it instead of repeating it.
- Review daily: fifteen focused minutes every day beats a two hour session once a week.
Privacy and Persistence
Everything happens on your device. Cards are written to local storage under a single key, the export is generated in the browser as a downloadable file, and the import reads the file you choose without sending it anywhere. If you use a shared computer, clear the deck before you leave or export it and import it again on your own device.

Frequently Asked Questions
Where are my flashcards stored?
In your browser's local storage, on your own device. Nothing is sent to a server. That also means the deck belongs to one browser: clearing site data removes it, so export a JSON backup before clearing cookies or storage.
How do I move a deck to another device or a classmate?
Press Export Deck to download a JSON file. On the other device, use Import Deck and choose that file. The import replaces the current deck with the imported one.
What format does the import expect?
A JSON file with a cards array, where each card has a front and a back string, exactly as produced by the export button. A plain array of front and back objects also works.
Can I edit a card after adding it?
Delete the card with the trash icon and add it again with the corrected text. The deck list on the left makes it easy to spot the card that needs fixing.
How many cards can a deck hold?
There is no fixed limit. The practical limit is browser storage, which comfortably holds thousands of text cards. If a deck gets very large, split it into subject decks so review sessions stay focused.
