Flashcard maker

How to make flashcards

1. Paste your list into Paste cards, one card per line, as term – definition. Check the preview: the term is on the left, the definition on the right. If a line split in the wrong place, pick the separator yourself.
2. Tap Add cards. To fix a card, edit it in the list; tap Picture to put a photo or drawing on either side.
3. Open Study, look at the term, tap the card (or press Space) to see the definition, and rate how well you knew it.
4. Use Learn to type the answers, or Match for a quick timed round of pairs.
5. Open Print, choose the card size, paper and double-sided or fold-in-half, and print at 100 %. Cut along the thin lines.

How the double-sided layout lines up

A duplex printer that flips on the long edge turns a portrait sheet about its vertical middle line, so whatever is printed at the left of the back lands behind the right of the front. The back page is therefore drawn mirrored: the back of the top-left card sits at the top right. On US Letter (215.9 × 279.4 mm) with 2.5 × 3.5 in cards, 9 cards fit in a 3 × 3 grid, starting 12.7 mm from the left edge; the backs start 12.7 mm from the right edge, so after the flip every back covers its front exactly. 3 × 5 in cards print upright (portrait), 4 to a sheet, because two upright cards fit side by side and two landscape ones do not; A7 cards print 4 to a sheet on both papers. Every card keeps at least 6 mm from the paper edge, which most printers cannot reach.

Printers do not all feed the second side perfectly: a shift of 1 to 2 mm is common, so keep the words away from the card edges (the layout leaves a padding) and test one sheet before a long run. Fold in half needs no duplex: fronts are printed on the left half against the dashed middle line and backs mirrored on the right, so folding along the line puts each back behind its front. The fold becomes one edge of each card, so you cut three sides.

Separators the paste box understands

In Auto mode each line is split at the first separator found in this order: a tab, a spaced dash (“ – ” or “ — ”), a spaced hyphen (“ - ”), a colon followed by a space, then a comma. So Paris: capital of France, on the Seine splits at the colon and keeps the comma in the definition, and well-known - famous keeps the hyphen in the term because it has no spaces around it. Lines with no separator are listed as skipped, not guessed.

What it cannot do

• No sync between devices: your decks live in this browser. Use Export CSV and Import CSV to move them.
• No AI-made cards: it does not write cards or definitions for you; you bring the list.
• No audio: cards cannot play pronunciations or recordings.
• Pictures are not in share links or CSV files; only the text travels.
• Up to 2,000 cards per deck and 1,000 characters per side. Share links longer than 2,000 characters (about 100 cards of a word and a short phrase; fewer with long definitions) may be cut by some chat apps; send the CSV instead.

Privacy and what is stored

Your cards never leave your device. Text and progress are saved in this browser's local storage, pictures in its IndexedDB, until you tap Clear everything. The page counts an anonymous page view and, when you study, print or open a share link, one of three fixed words (cards-study, cards-print, cards-share-open); never a card, a deck name or a score. Opening someone's share link saves nothing until you tap Save.

Questions

How do I make printable flashcards?

Paste your cards, one per line, as term – definition, then open the Print tab. Pick the card size (3 × 5 in, 2.5 × 3.5 in or A7) and your paper (Letter or A4), choose double-sided or fold-in-half, and tap Print. Each card has a thin cut line; print at 100 % (actual size), not fit to page.

Can I make flashcards with pictures?

Yes. In the card list, tap Picture on the front or back of any card and choose a photo or drawing from your device. Pictures show when you study, learn, match and print. They are shrunk to at most 800 pixels on the long side and kept in this browser only; share links and CSV files carry the text, not the pictures.

Is this flashcard maker free?

Yes. There is no account, no limit on the number of decks, no paid tier and no ads. Everything runs in your browser, and your cards are saved on this device until you clear them.

How do I print double-sided flashcards so the backs line up?

Choose Double-sided. The page prints the fronts on one page and the backs on the next, with the backs mirrored left to right, so when your printer flips the sheet on its long edge each back lands behind its own front. Set the printer to two-sided, flip on long edge, at 100 % scale. Without a duplex printer, choose Fold in half: fronts and backs print side by side on one page and you fold the sheet down the dashed middle line.

How does spaced repetition work here?

After you flip a card you rate it Again, Hard, Good or Easy. Again shows it again a minute later, Hard brings it back sooner than Good, Good waits 1 day for a new card, 6 days the second time and then the last gap times the card's ease (2.5 to start), and Easy always waits longer than Good. Each button shows its gap before you tap it, and the Study tab counts the cards due now. Worked example: a new card rated Good, Good, Good comes back after 1 day, then 6 days, then 15 days (6 × 2.5).
