Description

Lecture Search — Semantic Card Finder & AI Gap Analysis Lecture Search bridges the gap between your lecture slides and your existing Anki collection. It uses local semantic embeddings (SentenceTransformers with Apple Silicon GPU / CUDA acceleration) to search hundreds of thousands of flashcards in seconds, finding cards matching your PDF or PPTX slides. If your deck is missing key lecture concepts, the built-in AI Gap Analysis powered by Google Gemini automatically identifies uncovered topics and generates high-yield Cloze flashcards with embedded slide images. ✨ Key Features Instant Semantic Search : Searches your entire Anki collection (150,000+ cards) in seconds using local AI embeddings ( all-MiniLM-L6-v2 ). Supports both PDF and PPTX lecture presentations. Granular matching: choose Per Slide or Whole Document granularity. One-Click Deck Movement : Select matched cards and move them directly into a new target lecture deck (e.g., Lecture::Immunology Ch4 ). AI Gap Analysis (Gemini Integration) : Compares your lecture slides against your existing cards. Finds high-yield gaps and generates cloze-deletion cards with embedded slide images in the Extra field. 100% Local & Fast : Semantic embeddings run entirely on your local machine with Apple Silicon (MPS) and NVIDIA (CUDA) GPU acceleration. Step 3 — Open Lecture Search After the install completes, restart Anki and go to Tools → Lecture Search... (or press Ctrl+Shift+L / Cmd+Shift+L). ⚙️ Configuration Open Tools → Add-ons → Lecture Search → Config : similarity_threshold (default: 0.4 ): Cosine similarity cutoff (0.0 to 1.0). default_deck_prefix (default: "Lecture" ): Default prefix for created decks. gemini_api_key : Optional Gemini API key for AI Gap Analysis (get a free key at aistudio.google.com ). gemini_model (default: "gemini-2.5-flash" ): Gemini model for card generation. cards_per_gap (default: 2 ): Number of cloze cards generated per identified gap. ⌨️ Shortcut Mac / Windows / Linux : Ctrl+Shift+L (or Cmd+Shift+L on macOS) opens Lecture Search from anywhere in Anki.
