Notion Anki Flashcard Sync

An ETL pipeline that turns vocabulary sitting in a Notion database into Anki flashcards automatically. A GitHub Actions job orchestrates a daily run that extracts new Notion entries and transforms each into a definition through a three-tier fallback chain (Free Dictionary API → Merriam-Webster → Gemini), then queues the result; a local delivery step loads that queue into Anki via AnkiConnect as reversible cards, so one vocabulary entry becomes both a word→definition and a definition→word review card. Anki's own duplicate detection acts as the pipeline's data-quality validation step, keeping re-runs safe.
