How it works
- 1.Load PDF from Google Drive and extract full text content
- 2.Split text into manageable chunks using recursive character splitting
- 3.Generate embeddings and store chunks in vector database for semantic search
- 4.Receive user question through chat interface trigger
- 5.Retrieve most relevant document sections matching the query
- 6.Generate and return accurate answer grounded in PDF content
Use cases
- Enable employees to query company policies and procedures stored in PDF documents
