Huxley Pdf

Huxley Pdf is a Streamlit application for asking questions about uploaded PDFs. It extracts and chunks PDF text, creates OpenAI embeddings, retrieves relevant text by similarity, and uses a LangChain question-answering chain with OpenAI.

Practical overview

When it fits

Use it as a reference for a PDF question-answering interface or when exploring document ingestion and retrieval patterns. The README’s index-creation step is commented out, so it does not document a complete working retrieval setup.

Who it is for

  • People who want to explore question answering over personal PDF documents.
  • Developers examining or adapting a Python and Streamlit document-chat application.

Documented uses

  • Upload a PDF and ask a question about its contents.
  • Extract and split PDF text into overlapping chunks for retrieval-based question answering.
  • Use retrieved document text as context for an OpenAI answer-generation call.
Before you choose

Requirements & limits

The repository is public and specifies the MIT license. The documented interface includes an OpenAI API-key input.

  • The README describes PyMuPDF text extraction, 400-character chunks with 80-character overlap, OpenAI embeddings and LangChain question answering.
  • The README describes FAISS similarity search, but comments out the FAISS index-creation step.
  • The repository description mentions Pinecone, while the detailed implementation overview describes FAISS; it does not document a completed Pinecone workflow.
  • The README includes an installation heading but no substantive installation steps.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Upload a PDF and ask it a question

Use Huxley PDF’s documented interface and question-answering flow to ask about an uploaded PDF.

Before you start

  • A PDF file to upload.
  • An OpenAI API key; the application sidebar provides an input field for it.

Steps

  1. Enter your OpenAI API key in the sidebar.

  2. Upload a PDF using the file uploader, which accepts PDF files.

  3. Enter a question about the PDF in the question field.

  4. Read the response displayed in the application.

Expected outcome

The application displays a response generated using retrieved document content and the question-answering chain.

Guide limitations

  • The README says the FAISS index-creation call is commented out, so the documented retrieval path may not be operational as described.
  • The README’s installation section contains no setup instructions.
