Starts on a Google Drive event

When a PDF lands in Google Drive, indexes it into Pinecone with OpenAI embeddings, then answers WhatsApp questions via a Gemini RAG agent.

Drive Document Chat Agent

When files are added to Google Drive, embeds them into Pinecone with Gemini, letting a chat agent answer questions over the documents.

When files are added to Google Drive, indexes them into Milvus with Cohere embeddings so an OpenAI chat agent answers questions.

On manual run, indexes documents into Pinecone, then a Gemini agent retrieves context and writes outputs to Google Docs, Sheets, and Drive.
