langchain-ask-pdf and langchain-pdf-qa
Both implement the same LangChain-based RAG pattern for PDF question-answering using OpenAI LLMs, making them direct competitors offering functionally equivalent solutions with different code bases rather than complementary tools.
About langchain-ask-pdf
alejandro-ao/langchain-ask-pdf
An AI-app that allows you to upload a PDF and ask questions about it. It uses OpenAI's LLMs to generate a response.
Implements semantic search over PDF content by chunking text and using OpenAI embeddings to retrieve contextually relevant sections before feeding them to the LLM, preventing hallucinations on out-of-scope questions. Built with LangChain for orchestration and Streamlit for the web interface, it constrains model responses to document-grounded answers only.
