How to Use the Flashcard Maker

1Add cards to a deck — type a front and back one at a time, or paste a whole list in at once with Bulk Import.
2Switch to Study mode and click through your deck — click the card (or press Space) to flip it and reveal the answer.
3Grade each card Again, Hard, Good or Easy as you go — this schedules its next review automatically and drives the Due Cards Only filter.
4Back up your decks with Export All whenever it matters, so a full study set survives a browser change or a cleared cache.

Features

Seven study modes
Flip, Multiple Choice, True/False, Type the Answer, Fill in the Blank, Match the Pairs and a scored Test Mode.
Real card-flip animation
A genuine 3D flip, not a fade — click the card or press Space.
Real spaced repetition
SM-2 scheduling — Again/Hard/Good/Easy grading with an interval preview on every button.
Due Cards Only
Filter a session down to whatever is actually due for review today.
Images, math and cloze blanks
Attach a photo to any card, write LaTeX with $math$, and mark {{blanks}} for a real cloze-style test.
Tags + search across all decks
Tag any card, then filter or search every deck at once from the sidebar — not just the one you're in.
Streaks and activity stats
A day-streak counter, 14-day review chart, and a per-session breakdown of Again/Hard/Good/Easy.
Auto-graded quizzes
Multiple Choice, True/False and Type the Answer grade themselves and schedule the next review instantly.
Bulk import
Paste a whole list at once, split by pipe, comma, semicolon or tab.
CSV/TSV file import
Upload a spreadsheet or Anki/Quizlet export directly, with a preview before anything's added.
Swipe to grade
On the answer side, swipe or drag right for Good, left for Again — with a quick undo if you miss.
Drag-to-reorder + printable decks
Reorder cards by dragging them in Manage Cards, or print a deck as cuttable flashcards.
Text-to-speech
Read either side of a card aloud, on demand or automatically.
Full backup export/import
Every deck, every card and its status, saved as one restorable file.

Most "flashcard maker" tools online are really just a stack of index cards with a flip animation bolted on — type a front, type a back, click through them in whatever order they were entered. That's fine for a five-minute review, but it falls apart the moment you actually need to remember something a month from now. This one schedules cards the way a real spaced-repetition system does: grade a card, and its next appearance moves automatically, closer if you struggled, further out if it was easy.

Decks, Not One Long Pile

Cards live inside separate decks, so a biology exam and a half-finished language deck never bleed into each other. Each card carries its own ease factor, interval and due date under the hood, computed with the SM-2 algorithm — the same scheduling model behind Anki — and updated the instant you grade it, not on some batch job later.

What Actually Happens During a Study Session

Starting Study mode pulls every card in the active deck — or only the ones actually due, if Due Cards Only is switched on — optionally shuffles them, and steps through one at a time behind a real 3D CSS flip rather than a plain crossfade. Grading Again, Hard, Good or Easy runs the SM-2 formula on the spot, and in a Due Cards Only session, that card drops out of the remaining queue immediately since it's no longer due today no matter which grade it got.

Flip isn't the only way through a deck, either. Multiple Choice, True/False, Type the Answer, Fill in the Blank, Match the Pairs and a scored Test Mode all pull from the same cards and the same schedule — switch modes from the dropdown mid-study and nothing about your progress resets.

Three Study Sessions, Three Different Shapes

Cramming vocabulary the week before a language exam usually starts with Bulk Import — forty word/translation pairs pasted in at once — Shuffle switched on so the same five words don't lead every single session, and Due Cards Only keeping each day's pass to what's actually scheduled rather than the full list from scratch. Running a Pomodoro Timer alongside keeps each block to a fixed length instead of an open-ended scroll through the deck.

Reviewing lecture notes the night before a test looks different: terms get typed in one at a time straight out of a notepad, and the act of deciding what's worth turning into a card ends up doing half the studying by itself — a deck built this way is usually smaller and sharper than the notes it came from.

And for something spread across several days, a deck gets touched once daily with Due Cards Only on, letting weaker cards naturally surface more often than ones already graded Easy, with Reset Progress the day before the actual exam forcing one last full pass regardless of schedule. Watching the date itself on a Countdown Timer makes it obvious how many of those daily sessions are actually left.

Who This Is Actually Built For

  • Students prepping for exams — vocabulary, formulas, dates, definitions — anything better learned through active recall than passive re-reading.
  • Language learners — a word on the front, translation on the back, with the speaker icon for pronunciation on both sides.
  • Anyone studying for a certification — a dedicated deck per exam, separate from whatever else is on the same device.
  • Teachers building review material — Bulk Import turns an existing term/definition spreadsheet into a study deck in seconds.

A Few Things Worth Doing Differently

  • Write the front as a genuine question, not just a keyword — "What year did X happen" recalls better than a bare date fragment sitting alone on a card.
  • Turn Shuffle on once a deck is more than a handful of cards, so you're not just memorizing position order instead of the actual content.
  • Grade honestly, not optimistically — tapping Easy on a card you actually struggled with pushes its next review too far out, and Due Cards Only will hide it long before you've really got it.
  • Keep decks reasonably sized, 20–40 cards works better for one sitting than a single 300-card deck covering an entire semester.
  • Export a backup before any exam week browser change — a new laptop, a reinstalled browser, a cleared cache — not after.

Nothing Leaves Your Browser

No account, no install — every deck stays entirely in local storage on your own device, which is also why it opens as fast as any other tab instead of waiting on a server to hand your own cards back to you. The one trade-off is the obvious one: a deck built on one browser doesn't show up on another by itself, which is exactly what Export All and Import Backup are there to bridge.

When Something Looks Off

Graded a run of cards Easy by mistake? Reset Progress in Manage Cards clears the whole deck back to a fresh New schedule in one step — there's no per-card undo for a single grade once the toast disappears, so use this if a session got mismarked badly enough to matter.

Bulk Import added nothing, or fewer cards than expected? Almost always a delimiter mismatch — a comma-separated list won't parse correctly with Tab selected. Check one line against the chosen delimiter before importing anything long.

Deck missing on a different device? Expected — decks are stored per browser, per device, with nothing synced automatically. Export All on the original device, Import Backup on the other, and it moves across intact.

Due Cards Only showing nothing at all? Nothing in that deck is due right now — "Study All Cards Anyway" runs a full pass regardless of schedule, or Reset Progress restarts the deck from New if that's actually what you want.

Where This Tool Stops

A mature SRS ecosystem with custom algorithm parameters, shared community decks, image occlusion and a decade of add-ons is still a deeper tool than this one — Anki remains the right call for that level of configuration. This is deliberately a fast, private, single-device study tool instead: no automatic sync, no deck sharing with classmates, just Export/Import as the manual bridge whenever a deck needs to move somewhere else.
