Biology, the Mughal Empire, Spanish verbs, contract law, music theory, your driving theory test — whatever you are learning. Tell us the topic and what keeps catching you out, and you get a deck written for that. Reveal each answer, rate how well you knew it out of five, and every session is kept so you can see recall improve.
Not a generic pack. You name the subject, the specific topic, and what you keep getting wrong — the deck is written from that brief.
The answer stays hidden until you ask for it. Trying to remember first is the whole point — reading an answer you can already see teaches you nothing.
Rate each card from Blank to Instant. Nothing is overwritten, so you can see whether you are genuinely improving rather than guessing.
Your second run leads with the cards you knew least well. Your revision time goes where it is actually needed.
Facts, definitions, dates, formulas, vocabulary, comparisons — the material you need to have genuinely in your head rather than merely recognised on a page. You describe what you want to learn, in whatever subject, and Sanviora writes a deck of question-and-answer cards for exactly that. Students revising, people taking a certification, language learners, and anyone learning something for their own reasons all use the same flow.
One card at a time. You see the question. You try to answer it from memory. Then you reveal the answer and rate how well you actually knew it — Blank, Hard, Shaky, Good, or Instant. That rating is stored against that specific card and that specific session, so your history builds up rather than being replaced each time.
The next time you study the same deck, the cards you rated lowest come first. You spend your time on what you do not know yet, which is the single thing that makes revision efficient.
The deck is only as good as what you tell us. Be narrow: "photosynthesis" produces a far better deck than "biology", and "the Spanish subjunctive" beats "Spanish". Then say what you find hard, what the deck is for, and roughly what level you are at. "I have an exam in three weeks, I keep mixing up mitosis and meiosis, and I am fairly new to this" gives us far more to work with than a one-word topic.
Anyone with something to memorise. School and university students revising for exams; people working through a professional certification; language learners drilling vocabulary and grammar; and plenty of people learning purely out of interest — astronomy, art history, chess openings, the highway code.
If what you are preparing for happens to be a job interview, flashcards pair naturally with an AI mock interview — learn the material here, then practise saying it out loud there. That is one use among many, not what this is for.
Any of them. Science, medicine, history, geography, law, mathematics, languages, arts, business, a professional certification, or something you are learning purely for yourself. If it can be written as a question and an answer, it works.
No. Most decks have nothing to do with work. Flashcards are for anyone memorising anything — an exam, a certification, a language, or your own curiosity.
You choose, within the range your plan covers. Somewhere around ten to fifteen is one comfortable sitting; larger decks suit a subject you will come back to several times.
No. You can buy and study a deck without signing up. If you do create an account afterwards, your decks and your full study history move across with you.
Yes, as many times as you like, and that is the point. Every session is stored separately, and each new run leads with the cards you knew least well.
Yes. Open a deck you already own and choose "Add more cards on this topic". You pick a plan and pay for that deck as usual, and none of the new cards repeat anything already in the series.
It records how well you recalled that specific card. It sets the order of your next session and builds the recall average you see on your deck and your profile.
