Problem Solved

This workflow addresses the challenge of efficiently querying and retrieving information from large documents stored in Google Drive. By utilizing AI embeddings and a vector database, users can extract relevant information quickly, along with citations, thus saving time and enhancing productivity. It enables users to interact with their documents in a conversational manner, making the retrieval process intuitive and effective.

Workflow Steps

1. Manual Trigger: The workflow begins when the user clicks the "Execute Workflow" button.
2. Set File URL: The workflow sets the Google Drive file URL that will be processed.
3. Download File: The specified file is downloaded from Google Drive.
4. Add Metadata: Metadata such as file name and URL is added to the downloaded file for future reference.
5. Insert into Vector Store: The file is split into chunks and inserted into a Pinecone vector store for efficient querying.
6. Chat Trigger: Users can initiate a chat to ask questions based on the document content.
7. Get Top Chunks: The workflow retrieves the top relevant chunks from the vector store based on the user's query.
8. Prepare Chunks: The retrieved chunks are prepared for processing.
9. Generate Embeddings: AI embeddings are created for the prepared chunks to facilitate understanding.
10. Answer Query: The AI generates a response to the user's query using the context from the document chunks.
11. Compose Citations: Citations are compiled to provide references for the generated answer.
12. Generate Final Response: The final response, including the answer and citations, is prepared for the user.
