Anki®

This repo contains the source code for the computer version of Anki.

Anki is a powerful, intelligent flashcard program that makes remembering things easy.

📖 About Anki

Anki is a spaced repetition flashcard program. It helps you memorize information efficiently by presenting cards at optimal intervals based on your performance. Anki uses an algorithm to schedule reviews, ensuring you see cards right before you're about to forget them.

Key Features

• Spaced Repetition: Scientifically-proven algorithm for efficient learning
• Rich Media Support: Add images, audio, video, and LaTeX to your cards
• Cross-Platform: Available on Windows, macOS, Linux, iOS, and Android
• Synchronization: Keep your cards in sync across all your devices
• Extensible: Powerful add-on system for customization
• Open Source: Free and open-source software

🚀 Getting Started

For Developers

This is a complex project with multiple components:

• Backend: Rust (rslib/) - Core scheduling, database, and sync logic
• Python Library: (pylib/) - Python bindings and add-on API
• Frontend: TypeScript/Svelte (ts/) - Modern web-based UI
• Qt Interface: Python/Qt (qt/) - Desktop application wrapper

Quick Start

1. Prerequisites:

   • Rust (version specified in rust-toolchain.toml)
   • N2 or Ninja build system
   • Python 3.9+ (3.9 recommended)
   • Platform-specific tools (see platform docs below)

2. Clone the repository:

   git clone https://github.com/ankitects/anki.git
   cd anki
   

3. Install build tools:

   # Install N2 (recommended) or Ninja
   bash tools/install-n2
   

4. Platform-specific setup:

   • Windows
   • macOS
   • Linux

5. Build and run:

   # Build the project
   tools/build
   
   # Run Anki
   ./run
   

   (On Windows, use .\run instead)

For detailed development instructions, see the Development Guide.

Pre-built Python Wheels

If you're developing add-ons or need Python bindings without building from source, you can install pre-built wheels from PyPI:

pip install --pre aqt

See betas.ankiweb.net for more details.
