Show HN: A holiday side project to make Anki flashcards without breaking flow (github.com)

MasterFlasher, a new Android app, simplifies the process of creating Anki flashcards by converting shared text, URLs, local PDFs, or voice input into flashcards seamlessly. Utilizing the Gemini API, the app allows users to store content in a silent inbox and later extract readable text to generate flashcards, which can be reviewed and sent directly to AnkiDroid. This streamlined process enhances the learning experience by minimizing disruption while studying. The significance of this tool lies in its combination of AI and user-friendly design, particularly for students and educators looking to optimize their learning through spaced repetition. MasterFlasher employs advanced features like in-app content extraction from various sources, configurable prompts for fact generation, and maintains user privacy by using a Bring Your Own Key (BYOK) model for API calls. By securely handling API keys and processing data locally, the app ensures robust privacy while promoting efficient study habits through automation and AI-driven insights.
