About Flashcard Maker
Create study flashcards with flip animation. Import, export, and shuffle. Free, no sign-up required.
How to use
- Type a question, term, or prompt into the Front (question) input. Keep it to one fact per card — splitting compound questions into separate cards makes recall measurably stronger (testing effect, Roediger & Karpicke 2006).
- Type the matching answer into the Back (answer) input and click the + button to add the card to your deck. The card appears in the list below; you can keep adding without losing the inputs.
- Click anywhere on the displayed card to flip between front and back. Use the Prev / Next buttons to step through your deck in order, or click Shuffle to randomize for a quiz session.
- Use the × on any list item to delete a single card. Click Clear All to wipe the deck and start over — there is no undo, so export first if the deck matters.
- Click Export JSON to download your deck as a file you can re-import later, share with a study group, or back up. Import lets you load a previously-saved deck back into the maker.
- Click Save Deck to keep the deck in your browser's local storage so it loads automatically next visit. Aim for 20-30 new cards per session, then review with shuffle until you can answer 90%+ correctly.
Frequently asked questions
What makes a flashcard actually effective?
One fact per card, with the answer concise enough that you can verify recall in two seconds. Cards that ask 'list five causes of WWI' fail because partial recall feels like success. Split compound questions into five separate cards. Use your own words on the back, not the textbook's — generation effort during card creation already encodes the material. Add an image when the concept is visual; image-paired cards retain ~30% better than text-only (dual coding theory).
What is spaced repetition and how does it work?
Spaced repetition shows cards just before you would forget them, exploiting the spacing effect first measured by Ebbinghaus in 1885. The Leitner system (1972) uses physical boxes: cards you get right move to a slower-review box; cards you miss go back to the daily box. Algorithms like SM-2 (Anki, SuperMemo) calculate exact next-review intervals based on your self-rated difficulty. Studies find spaced practice produces 2-3x better long-term retention than the same study time crammed.
How many cards should I review per session?
20-30 new cards per session is the sustainable maximum for most people; review sessions including older material can run 50-150 cards in 15-25 minutes. Beyond 25 minutes, accuracy drops sharply — diminishing returns are a real cognitive limit, not laziness. Daily 20-minute sessions outperform a single 3-hour Sunday cram by a wide margin. Learning happens between sessions, during sleep consolidation, not during the session itself.
Should I write the cards myself or use pre-made decks?
Make your own. The act of converting a chapter into question-and-answer cards is itself a deep encoding step — Bloom's taxonomy calls it the 'application' level of learning. Pre-made decks save time but skip this step, and cards written by someone else often miss the specific angle your exam or job will test. A reasonable hybrid: import a pre-made deck for vocabulary or formulas, then write your own cards for concepts and applications.
Why flip cards instead of just reading the answer?
Active recall (forcing yourself to retrieve the answer before flipping) is dramatically stronger than passive reading — this is the 'testing effect.' Even guessing wrong helps memory more than re-reading the right answer, because the wrong attempt creates a hook for the correction. The brief 'I don't know' before flipping is the most valuable second of the entire session; rushing past it to read the answer wastes the cognitive setup.
Can I import flashcards from Quizlet or Anki?
This tool's Import button accepts JSON files exported by ToolFluency Flashcard Maker. For Quizlet/Anki content, export your deck to CSV or text, then convert to JSON with a column for 'q' (front) and 'a' (back). Many simple decks paste in cleanly through the Front/Back input fields if you have under a hundred cards. For larger decks, Anki is better suited to long-term spaced repetition; this tool is best for quick session-based study.
Are my cards saved if I close the browser?
Click Save Deck before closing — that writes the deck to your browser's local storage, where it persists between sessions on the same browser and device. Local storage does not sync to other devices, and clearing browser data wipes it. For permanent backup, click Export JSON and save the file somewhere durable (cloud drive, email to yourself). Import the file when you want the deck back.
