Rember

Rember is an AI-powered flashcard application designed to generate study cards from a variety of inputs including PDFs, YouTube videos, reference books, pasted text, and AI chats. Built as an AI canvas, it aims to help users retain information efficiently by following spaced repetition practices and incorporating the FSRS algorithm. Users can study the generated flashcards directly within the application, use it offline as a progressive web app, or sync their cards with Anki.

• Generates flashcards from diverse inputs such as PDFs, YouTube videos, reference books, pasted text, and AI chats
• Integrates the FSRS algorithm for spaced repetition with options to pause, snooze, or undo reviews
• Supports an MCP integration allowing users to create cards directly from Claude, ChatGPT, or other compatible chat apps
• Offers an Anki add-on to generate cards in Rember and review them in Anki
• Provides custom instructions to control how the AI phrases, structures, and formats cards
• Organizes cards into decks to help users group and prioritize their reviews
• Syncs automatically across desktop and mobile devices with offline support

Pros

• Flexibility in input sources allows learners to turn books, videos, and chat transcripts directly into structured study material
• Integration with the FSRS algorithm provides structured, scientifically-backed spaced repetition scheduling for memory retention
• Cross-device synchronization and PWA support permit reviewing materials offline on both mobile and desktop
• Compatibility with Anki lets users leverage AI generation while maintaining traditional review workflows if desired

Cons

• The free plan is capped at AI card generation for up to 30 notes per month
• Dedicated native mobile applications are not yet available, as the service currently operates as a progressive web app
• The card editor is optimized specifically for desktop Chrome-based browsers such as Chrome, Arc, and Microsoft Edge
• Certain card types such as text occlusions, image occlusions, multiple choice, and chess move practice cards are planned for the future rather than available immediately

Rember is well-suited for serious learners, students, and professionals who consume heavy volumes of digital content and want to automate the creation of spaced repetition flashcards from books, videos, or AI discussions. It is also appropriate for users looking for a modern interface who want to sync cards into Anki. It is a poor fit for users seeking native mobile apps today or those who require advanced specialized card types like image occlusions immediately.

Rember operates on a freemium model. The Free plan allows users to generate cards with AI for up to 30 notes per month. The Pro plan costs $8 per month and increases the limit to generate cards with AI for up to 1,000 notes per month, alongside priority support.

Unlike traditional spaced repetition software where users must write flashcards manually, Rember automates the process by generating atomic, unambiguous flashcards directly from various source materials via an AI canvas and MCP integrations with chat applications. It also pairs this automated generation with modern interface defaults and the FSRS algorithm, separating itself from older, more complex tools.

Rember integrates with Anki, Claude Desktop, ChatGPT, PDFs, YouTube videos, and any chat apps that support the Model Context Protocol (MCP).
