Flashcards Features
Everything you need to create useful cards, review at the right time, keep studying offline, and stay in control of your learning data.
Smarter Reviews with FSRS
Review the cards that are due today. FSRS brings difficult cards back sooner and waits longer before showing familiar ones again.
AI-Assisted Card Creation
Ask AI to help create cards, improve their wording, or clarify an answer. You stay in control of what gets saved.
Offline Study with Automatic Sync
Keep reviewing on your mobile device without an internet connection. Changes sync automatically so you can continue on the web, iOS, or Android.
Import, Export, and Own Your Data
Move your learning materials in or out whenever you like. Portable exports include your cards, tags, and related media.
Works with AI Agents
Connect through MCP or the Agent API so AI agents can help create, improve, and organize your cards.
Free and Self-Hostable
Use the hosted app for free, inspect the open-source code, or run it on your own infrastructure.
