The workflow sends the audio to AssemblyAI for transcription, speaker labeling, and summarization into bullet points.\n3. The full transcript is then chunked, embedded using Google Gemini, and stored in a Pinecone vector database for future retrieval.\n4. A record of the uploaded file is added to a Google Sheet.\n5. Separately, an AI chatbot can answer questions by retrieving relevant information from the Pinecone vector database using Google Gemini.\n\n### Setup\n- [ ] Connect your AssemblyAI API key.\n- [ ] Connect your Pinecone API key and specify your Pinecone index for audio summaries.\n- [ ] Connect your Google Gemini (PaLM) API account.\n- [ ] Connect your Google Sheets account and specify the spreadsheet and sheet name for logging with column named file and status."
