Starts on a Gmail event

On an incoming Gmail email, classifies it with OpenAI, answers from a Pinecone knowledge base built on Drive files, and replies via Gmail.

Drive Knowledge Base Chat Agent

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.

On a chat message or Google Drive upload, embeds files into Supabase and answers questions with an OpenAI RAG agent.
