PDFToChat is an open-source Next.js web application that lets users upload PDFs and chat with them using AI. It uses Together AI's Mixtral LLM, Chroma Cloud for hybrid vector search, and LangChain.js for the RAG pipeline.

Use cases

• chat with pdf documents using ai
• ask questions about a pdf
• summarize and query research papers
• build a document question-answering app
• self-host a pdf chatbot
• deploy a rag app on vercel

When to choose

• you want a ready-to-deploy open-source PDF chat app
• you need a reference implementation of RAG with Next.js and LangChain
• you want hybrid dense+sparse vector search over documents

When to avoid

• you need fully local/offline processing since it depends on cloud services
• you need a production SaaS without setting up multiple third-party API keys
• you need to chat with non-PDF file formats
