AnkiForge

AI-powered flashcard generation for Anki — create high-quality cards in seconds using any LLM via OpenRouter.

<!-- Replace with actual screenshot after taking them -->

What is AnkiForge?

AnkiForge is a free, open-source Anki add-on that generates flashcards using AI. Instead of spending hours writing cards by hand, just type a few words or paste your study notes — AnkiForge creates complete, ready-to-study cards with definitions, examples, audio, and images.

It works with any model available on OpenRouter (GPT-4o, Claude, Gemini, Llama, and 200+ others), so you choose the price/quality balance that works for you.

Features

5 Generation Modes

Why AnkiForge?

• Any LLM model — pick from 200+ models on OpenRouter, from free to state-of-the-art
• Cost estimation — see the price before generating, track actual spending in real time
• Custom prompts — tweak AI instructions for any mode to fit your study style
• Code highlighting — cards render code blocks with syntax highlighting via highlight.js
• Batch generation — enter multiple words or questions at once
• Progress tracking — real-time progress bar with cancel support
• Beautiful card templates — styled HTML/CSS cards that look great in both light and dark mode
