A very simple example of how to ask questions to a PDF document using Langchain and OpenAI

This demo uses

• SvelteKit
• OpenProps
• Langchain JS/TS

Upload a PDF document and ask questions about it. The questions are sent to OpenAI and the answers are extracted from the PDF using Langchain.

The PDF and embeddings are stored locally in the static directory. There is no need to sign up for a vector database like Pinecone.
