Enjoy creating and reviewing flashcards

Spaced repetition is a learning technique that enhances memory retention by reviewing information at strategically increasing intervals. It leverages two key psychological principles: the forgetting curve, which shows how memories fade over time, and the spacing effect, which demonstrates that spreading reviews strengthens long-term retention. By estimating when memories fade, spaced repetition schedules reviews to help you remember efficiently.

Active recall is a study technique where you actively retrieve information from memory instead of passively reviewing it. For example, asking yourself, "What is spaced repetition?" and answering without looking strengthens your memory far more effectively than simply re-reading the answer.

A remb is the basic unit in Rember, made of the content you want to remember and some cards to help you practice and maintain that memory over time. Rembs are powerful because they allow you to group related cards together and add additional information like the sources of the information you are trying to remember.

Rember is currently free to use. Our goal is to make flashcard learning so enjoyable that more people can experience its proven benefits. As we add advanced features and AI capabilities, we'll introduce premium options, while keeping core functionality free. Join us early and help shape Rember.

Your content is private by default and will remain so. You can choose to share it via a link, but your review data will always stay private.

Rember works on all modern browsers, including mobile. The card editor is optimized for desktop Chrome-based browsers (Chrome, Arc, Microsoft Edge). We recommend creating and editing cards on desktop and reviewing them on either desktop or mobile.

Rember is currently a PWA (progressive web app) that works on both desktop and mobile, even when you are offline. You can also add an icon to your home screen on Android and iOS for faster access. Once we reach maturity with the PWA, we will likely introduce mobile apps.

Not yet, but we're planning to add support for creating rembs and cards from sources like PDFs and websites, and we're exploring a Chrome Extension. Share your ideal workflow with us — we'd love your input as we shape these features.

Rember supports question-answer cards, multiple choices cards, and text occlusions (fill-in-the-blank). We're also planning to add image occlusions and special card types, such as those for practicing chess moves.

Anki, and SuperMemo before it, demonstrated the power of digital flashcards but can feel overwhelming due to their complex interfaces. Rember combines spaced repetition and active recall with a simple, intuitive design, making it easier to focus on learning without being slowed down by the tool itself.

Rember currently supports exporting cards to Anki, but not review data. In the future, we plan to add support for importing Anki cards and review data, making the transition smoother.
