What is spaced repetition and why does it work?
Spaced repetition means reviewing information at increasing time intervals: cards you remember easily come back less often, and the ones you struggle with come back more often. Because it times reviews to when your memory is fading, it produces more durable learning than massed review or passive rereading. Combined with active recall, it is one of the most efficient ways to lock in a lot of material before an exam. The fading it is timed against is the curve Ebbinghaus first plotted in 1885.
How does WeSolve+ do spaced repetition?
WeSolve+ generates smart review cards from your notes and reshows them at increasing intervals inside the app. When you know a card well the interval grows; when you struggle it shrinks, so you spend time on the topics that need it most. Alongside the cards, the same material also becomes an explained quiz and an audio recap, so you reinforce spaced repetition with testing and listening. Cepeda and colleagues reviewed 254 spacing experiments in 2006 and found the widening gap, not the extra time, carried the gain. The interval is not guesswork, it comes from a named scheduler: SM-2 and FSRS, and you can pick either. SM-2 is the classic SuperMemo derived schedule that has been in use for decades; FSRS is a newer scheduler that learns from your own answer history and fits the interval to you. Knowing which one a tool runs matters, because most apps that say "smart review" never say.
Where do the cards come from, do I build them myself?
No, the AI builds the cards for you. Upload a PDF, photo or notes and WeSolve+ creates review cards faithful to that source in 10 to 20 seconds. Cards are derived only from the material you upload and stay faithful to it, with no invented facts. So instead of building cards by hand like in Anki, you start spaced repetition quickly from your existing notes.
Where spaced repetition runs
In the browser and on iPhone, on the cards built from your own uploads. Items you miss come back on later days without you scheduling anything, which is the entire mechanism and the part people abandon when they try to run it by hand. Start free; the plan figures live on pricing.
What changes compared with fixed revision?
In fixed revision every topic gets an equal share of time, including the ones you already know. With spacing, time moves toward what you actually forget. WeSolve+ applies it simply: a correct answer lengthens the interval, a miss shortens it. The result is more new material retained in the same hour. The usual blocker for this method is writing the cards, which is where most people stop; here the cards are generated from your PDF in 10 to 20 seconds. Enter your exam date and the daily card count is set from the days remaining. Dunlosky and colleagues ranked distributed practice among the two techniques with the strongest evidence across subjects and ages.

Does WeSolve+ really do spaced repetition?
Yes. WeSolve+ reshows the cards it generates at increasing intervals; cards you remember well come back less often, and ones you struggle with come back more often.
Do I build the cards myself?
No. You upload a PDF, photo or notes and the AI builds review cards faithful to that source in 10 to 20 seconds. Cards are derived only from the material you upload.
Is spaced repetition free?
You can start free in the browser and on iPhone, on cards built from your own uploads. The plan figures are on the pricing page.
Is there any study mode besides cards?
Yes. From the same material you also get an explained quiz, an audio recap and duels with friends, so you reinforce spaced repetition with testing and listening.
