What is the Flashcard Maker?

A flashcard maker lets you build a deck of question-and-answer cards and revise them in a flip-based review mode, marking each card known or unknown so you can repeat only the ones you missed.

  • Shuffle-and-flip review mode with known / review-again tracking
  • Repeat just the cards you missed at the end of a session
  • Bulk paste with a “term | definition” separator for fast deck building
  • Reverse mode that shows the definition first for harder recall practice
  • JSON and CSV export and import, with proper quoting for commas in cards
  • Saved in your browser's local storage — never uploaded, no sign-up

How to use the Flashcard Maker

  1. 1

    Type a term on the front of each card and its definition on the back, adding rows as you go.

  2. 2

    Or paste a list where each line reads “term | definition” and press Add these cards.

  3. 3

    Press Study to shuffle the deck and begin; click a card to reveal the other side.

  4. 4

    Mark each card as known or as one to review again as you work through the deck.

  5. 5

    Repeat only the cards you missed, and export the deck as JSON or CSV to keep a backup.

About the Flashcard Maker

The ByteTools Flashcard Maker gives you a full study loop in one page: type your cards, hit study, and work through a shuffled deck one card at a time. Click a card to flip it, mark it as known or as one to review, and at the end you can go straight back through only the cards you missed — the part of active recall that actually moves the needle.

Building a deck is quick. Add cards one at a time, or paste a whole list where each line is “term | definition” and the tool splits it for you. You can flip the deck so the definition is shown first, which is how you practise recall in the harder direction. Existing decks come in as JSON or CSV, and your own deck exports to either format.

Your deck is saved in this browser's local storage so it is waiting for you next visit, but it is never uploaded and there is no account. That also means clearing your browsing data removes it, so export a copy of anything you want to keep.

Frequently asked questions

Are flashcards actually an effective way to revise?

Testing yourself instead of rereading — retrieval practice — is one of the best-evidenced study techniques there is, and flashcards are the simplest way to do it. The gain comes from trying to recall the answer before you flip, so resist peeking even when the answer feels close.

Where are my flashcards saved?

In your browser's local storage on this device only. They are not sent to a server and no one else can see them. If you clear your browsing data, use private browsing, or move to another computer, the deck will not follow you — export the JSON or CSV first.

Can I import flashcards from another app?

Yes, if you can export them as CSV with a front column and a back column, or as JSON with front and back keys. Drop the file onto the import area and the deck loads. The CSV reader handles quoted fields, so commas inside a definition are safe.

How many cards should be in one deck?

Most people work best with twenty to forty cards per session, split by topic rather than one huge deck. Smaller decks come round more often, which means more repetitions of the material you are actually struggling with.

Does this flashcard maker use spaced repetition?

Not in the scheduling sense — there is no algorithm deciding when a card returns days later. What it does give you is within-session spacing: the deck is shuffled, and cards you mark for review come back immediately in a focused second pass.

Can I print my flashcards?

Export the deck as CSV and open it in a spreadsheet, then print it as a two-column table to cut up. The CSV keeps every card's front and back paired, so nothing gets scrambled on the way out.
