Rember

Rember is an AI flashcard tool that turns whatever a learner is studying into spaced repetition cards. It is built around an AI canvas where the user states in natural language what they want to remember, and Rember generates cards that follow best practices from the spaced repetition community, such as testing deep understanding, keeping each card atomic and unambiguous, and avoiding yes or no questions. Input can be a concept such as linear algebra basics, a reference to a book, pasted text, a PDF, a URL or a YouTube video. A Rember MCP server lets users say add to Rember inside Claude or ChatGPT chats so that conversations become cards. Custom instructions control how the AI phrases, structures and formats cards. Reviews use the FSRS scheduling algorithm, with options to pause, snooze or undo, and cards are organized into decks. The app works offline and syncs between desktop and mobile. Users who prefer Anki can generate cards in Rember and review them there through an add on. It is built for serious learners such as students, researchers and self taught professionals. Content is private by default and can be shared through a link. The Free plan generates cards with AI for up to 30 notes per month. The Pro plan costs $8 per month, allows up to 1,000 notes per month and adds priority support.
